    ################### Location Requirements and Considerations

    |WARNING

    | |---| |To prevent possible equipment damage, personal injury or death, the following bullet points must be observed when installing the unit.|

    Follow the instructions listed below when selecting a furnace location. Refer also to the guidelines provided in the Combustion and Ventilation Air Requirements section in this manual or the installation instructions for details.

  • • Centrally locate the furnace with respect to the proposed or existing air distribution system.
  • • Ensure the temperature of the return air entering the furnace is between 55°F and 100°F when the furnace is heating.
  • • If the furnace is installed in an application where the typical operating sound level of a furnace is deemed objectionable, an optional sound reduction kit is available. Consult your local distributor for more details.
  • • Provide provisions for venting combustion products outdoors through a proper venting system. Special consideration should be given to vent/flue pipe routing and combustion air intake pipe when applicable.
  • • 90% Furnaces: Refer to the Vent/Flue Pipe and Combustion Air Pipe - Termination Locations section in this manual or the installation instructions for appropriate termination locations. Also for 90% furnaces, refer to the Vent/Flue Pipe and Combustion Air Pipe - Termination Locations section in this manual or the installation instructions to determine if the piping system from furnace to termination can be accomplished within the guidelines given. NOTE: The length of flue and/or combustion air piping can be a limiting factor in the location of the furnace.
  • • Locate the 90% furnaceso that the condensate can be piped at a downward slope away from the furnace to the drain. Do not locate the furnace or its condensate drainage system in any area subject to below freezing temperatures without proper freeze protection. Refer to the Condensate Drain Lines and Trap section in this manual or the installation instructions for further details.
  • • Set the 90% furnace on a level floor to enable proper condensate drainage. If the floor becomes wet or damp at times, place the furnace above the floor on a concrete base sized approximately 1-1/2” larger than the base of the furnace. Refer to the Horizontal Applications and Considerations section in this manual or the installation instructions for leveling of horizontal furnaces.
  • • Ensure upflow or horizontal furnaces are not installed directly on carpeting, or any other combustible material. The only combustible material allowed is wood.
  • • A special accessory subbase must be used for upright counterflow unit installations over any combustible material (including wood). Refer to subbase instructions for installation details. NOTE: A subbase will not be required if an air conditioning coil is located beneath the furnace between the supply air opening and the combustible floor.
  • • Exposure to contaminated combustion air will result in safety and performance-related problems. Do not install the furnace where the combustion air is exposed to the following substances:
  • chlorinated waxes or cleaners chlorine-based swimming pool chemicals water softening chemicals deicing salts or chemicals carbon tetrachloride halogen type refrigerants cleaning solutions (such as perchloroethylene) printing inks paint removers varnishes hydrochloric acid cements and glues antistatic fabric softeners for clothes dryers and masonry acid washing materials

  • • Isolate a nondirect furnace from an area contaminated by any of the above substances. This protects the nondirect vent furnace from airborne contaminants. To ensure that the enclosed non-direct vent furnace has an adequate supply of combustion air, vent from a nearby uncontaminated room or from outdoors. Refer to the Combustion and Ventilation Air Requirements section in this manual or the installation instructions for details.
  • • If the furnace is used in connection with a cooling unit, install the furnace upstream or in parallel with the cooling unit coil. Premature heat exchanger failure will result if the cooling unit coil is placed ahead of the furnace.
  • • If the furnace is installed in a residential garage, position the furnace so that the burners and ignition source are located not less than 18 inches (457 mm) above the floor. Protect the furnace from physical damage by vehicles.
  • • If the furnace is installed horizontally, the furnace access doors must be vertical so that the burners fire horizontally into the heat exchanger. Do not install the unit with the access doors on the “up/top” or “down/ bottom” side of the furnace.
  • ################### Clearances and Accessibility

    Installations must adhere to the clearances to combustible materials to which this furnace has been design certified. The minimum clearance information for this furnace is provided on the unit’s clearance label. These clearances must be permanently maintained. Refer to Specification Sheet for minimum clearances to combustible materials. Clearances must also accommodate an installation’s gas, electrical, and drain trap and drain line connections. If the alternate combustion air intake or vent/flue connections are used on a 90% furnace, additional clearances must be provided to accommodate these connections. Refer to Vent Flue Pipe and Combustion Air Pipe section in this manual or the installation instructions for details. NOTE: In addition to the required clearances to combustible materials, a minimum of 24 inches service clearance must be available in front of the unit.

    A furnace installed in a confined space (i.e., a closet or utility room) must have two ventilation openings with a total minimum free area of 0.25 square inches per 1,000 BTU/hr of furnace input rating. One of the ventilation openings must be within 12 inches of the top; the other opening must be within 12 inches of the bottom of the confined space. In a typical construction, the clearance between the door and door frame is usually adequate to satisfy this ventilation requirement.

    ################### Furnace Suspension

    If suspending the furnace from rafters or joist, use 3/8” threaded rod and 2”x2”x1/8” angle iron as shown in the following figure. If the furnace is installed in a crawl space it must also be suspended from the floor joist or supported by a concrete pad. Never install the furnace on the ground or allow it to be exposed to water. The length of rod will depend on the application and the clearances necessary.

    Existing Furnace Removal NOTE: When an existing furnace is removed from a venting system serving other appliances, the venting system may be too large to properly vent the remaining attached appliances.

    The following vent testing procedure is reproduced from the American National Standard/National Standard of Canada for Gas-Fired Central Furnaces ANSI Z21.47, latest edition, CSA-2.3b, latest edition Section 1.23.1.

    The following steps shall be followed with each appliance connected to the venting system placed in operation, while any other appliances connected to the venting system are not in operation:

  • a. Seal any unused openings in the venting system.
  • b. Inspect the venting system for proper size and horizontal pitch, as required by the National Fuel Gas Code, ANSI Z223.1 or the CSA B149 Installation Codes and these instructions. Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
  • c. In so far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they shall operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.
  • d. Follow the lighting instructions. Place the appliance being inspected in operation. Adjust thermostat so appliance shall operate continuously.
  • e. Test for draft hood equipped spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle.
  • f. After it has been determined that each appliance connected to the venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance to their previous conditions of use.
  • g. If improper venting is observed during any of the above tests, the common venting system must be corrected.
  • Corrections must be in accordance with the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 and/or CSA B149 Installation Codes.

    If resizing is required on any portion of the venting system, use the appropriate table in Appendix G in the latest edition of the National Fuel Gas Code ANSI Z223.1 and/or CSA B149 Installation Codes. Thermostat Requirements A high quality single stage thermostat with a “C” terminal is recommended to control the G*ES9* and A*ES9* furnace. Thermostat Location

    In an area having good air circulation, locate the thermostat about five feet high on a vibration-free inside wall. Do not install the thermostat where it may be influenced by any of the following:

  • • Drafts, or dead spots behind doors, in corners, or under cabinets.
  • • Hot or cold air from registers.
  • • Radiant heat from the sun.
  • • Light fixtures or other appliances.
  • • Radiant heat from a fireplace.
  • • Concealed hot or cold water pipes, or chimneys.
  • • Unconditioned areas behind the thermostat and dehumidistat, such as an outside wall.
  • ######## COMBUSTION AND VENTILATION AIR REQUIREMENTS

    |WARNING

    | |---| |Possible property damage, personal injury or death may occur if the furnace is not provided with enough fresh air for proper combustion and ventilation of flue gases. Most homes require outside air be supplied to the furnace area.|

    Improved construction and additional insulation in buildings have reduced heat loss by reducing air infiltration and escape around doors and windows. These changes have helped in reducing heating/cooling costs but have created a problem supplying combustion and ventilation air for gas fired and other fuel burning appliances. Appliances that pull air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increase the problem by starving appliances for air.

    When the furnace is installed as a direct vent (2-pipe) furnace, no special provisions for air for combustion are required. However, if this furnace is to be installed in the same space with other gas appliances, such as a water heater, ensure there is an adequate supply of combustion and ventilation air for the other appliances. Refer to the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 (Section 9.3), or CAN/CGA B149 Installation Codes (Sections 7.2, 7.3, or 7.4), or applicable provisions of the local building codes for determining the combustion air requirements for the appliances.

    Most homes will require outside air be supplied to the furnace area by means of ventilation grilles or ducts connecting directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces.

    The following information on air for combustion and ventilation is reproduced from the National Fuel Gas Code NFPA 54/ANSI Z223.1 Section 9.3.

    9.3* Air for Combustion and Ventilation.

    Page 6

  • 9.3.1 General.
  • 9.3.1.1 Air for combustion, ventilation, and dilution of flue gases for appliances installed in buildings shall be obtained by application of one of the methods covered in 9.3.2 through 9.3.6. Where the requirements of 9.3.2 are not met, outdoor air shall be introduced in accordance with methods covered in 9.3.3 through 9.3.6.
  • Exception No. 1: This provision shall not apply to direct vent appliances.

  • 9.3.1.2 Appliances of other than natural draft design and other than Category 1 vented appliances shall be provided with combustion, ventilation, and dilution air in accordance with the appliance manufacturer’s instructions.
  • 9.3.1.3 Appliances shall be located so as not to interfere with proper circulation of combustion, ventilation, and dilution air.
  • 9.3.1.4 Where used, a draft hood or a barometric draft regulator shall be installed in the same room or enclosure as the appliance served so as to prevent any difference in pressure between the hood or regulator and the combustion air supply.
  • 9.3.1.5 Makeup air requirements for the operation of exhaust fans, kitchen ventilation systems, clothes dryers, and fireplaces shall be considered in determining the adequacy of a space to provide combustion air requirements.
  • 9.3.2 Indoor Combustion Air. The required volume of indoor air shall be determined in accordance with the method in 9.3.2.1 or 9.3.2.2 except that where the air infiltration rate is known to be less than 0.40 ACH, the method in 9.3.2.2 shall be used. The total required volume shall be the sum of the required volume calculated for all appliances located within the space. Rooms communicating directly with the space in which the appliances are installed through openings not furnished with doors, and through combustion air openings sized and located in accordance with 9.3.2.3, are considered a part of the required volume.
  • 9.3.2.1* Standard Method. The minimum required volume shall be 50 ft 3 per 1,000/Btu/hour (4.8m3/kW).
  • 9.3.2.2* Known Air Infiltration Rate Method. Where the air infiltration rate of a structure is known, the minimum required volume shall be determined as follows:
  • (1) For appliances other than fan-assisted, calculate using the following equation:
  • Required Volume other > 21 ft3 I other ACH 1000 Btu/hr

  • (2) For fan-assisted appliances, calculate using the following equation:
  • Required Volume fan > 15 ft3 I fan ACH 1000 Btu/hr

    where: I other = all appliances other than fan-assisted input in Btu

    per hour

    I fan = fan-assisted appliances input in Btu per hour ACH = air change per hour (percent of volume of space

    exchanged per hour, expressed as a decimal)

  • (3) For purposes of this calculation, an infiltration rate greater than 0.60 ACH shall not be used in the equations in 9.3.2.2(1) and 9.3.2.2(2).
  • 9.3.2.3 Indoor Opening Size and Location. Openings used to connect indoor spaces shall be sized and located in accordance with the following:
  • (1)*Combining spaces on the same story. Each opening shall have a minimum free area of 1 in.2/1000Btu/hr (2200 mm2/kW) of the total input rating of all appliances in the space but not less than 100 in.2 (0.60m2). One opening shall commence within 12 in. (300 mm) of the top, and one opening shall commence within 12 in. (300 mm) of the bottom, of the enclosure [see Figure A.9.3.2.3(1)].

  • ################### Horizontal Applications and Considerations

    Horizontal applications, in particular, may dictate many of the installation’s specifics such as airflow direction, ductwork connections, flue and/or combustion air pipe connections, etc. The basic application of this furnace as a horizontal furnace differs only slightly from an upright installation. When installing a furnace horizontally, additional consideration must be given to the following:

    ################### Drain Trap and Lines

    In horizontal applications the condensate drain trap is secured to the furnace side panel, suspending it below the furnace. A minimum clearance of 5.5” below the furnace must be provided for the drain trap. Additionally, the appropriate downward piping slope must be maintained from the drain trap to the drain location. Refer to Condensate Drain Trap and Lines section in this manual or the installation instructions for further details. If the drain trap and drain line will be exposed to temperatures near or below freezing, adequate measures must be taken to prevent condensate from freezing. NOTE: The use of insulation and/or heat tape is recommended. Failure to provide proper condensate drainage can result in property damage.

    ################### Leveling

    Leveling ensures proper condensate drainage from the heat exchanger and induced draft blower. For proper flue pipe drainage, the furnace must be level lengthwise from end to end. The furnace should also be level from back to front or have a slight tilt with the access doors downhill (approximately 3/4”) from the back panel. The slight tilt allows the heat exchanger condensate, generated in the recuperator coil, to flow forward to the recuperator coil front cover.

    In horizontal installations with the furnace laying on the left hand side, the alternate vent connection may be used. In this configuration the internal elbow is removed. The standard piping connections may also be used in these positions. Refer to Vent/Flue Pipe and Combustion Air Pipe section in the installation instructions for details concerning the conversion to the alternate vent/flue and combustion air connections on the 90% furnace.

    NOTE: Alternate “vertical” piping connections can not be used when an upflow 90% furnace is installed with supply air discharging to the right or when a counterflow furnace is installed with supply discharging to the left. In this case, use the standard flue and combustion air piping connections.

    ################### Alternate Electrical and Gas Line Connections

    Furnaces have provisions allowing for electrical and gas line connections through either side panel. In horizontal applications the connections can be made either through the “top” or “bottom” of the furnace.

    ################### Drain Pan

    A drain pan must be provided if the furnace is installed above a conditioned area. The drain pan must cover the entire area under the furnace (and air conditioning coil if applicable).

    ################### Freeze Protection

    If the drain trap and drain line will be exposed to temperatures near or below freezing, adequate measures must be taken to prevent condensate from freezing. NOTE: The use of insulation and/or heat tape is recommended. Failure to provide proper condensate drainage can result in property damage.

    ################### Propane Gas and/or High Altitude Installations

    |WARNING

    | |---| |Possible property damage, personal injury or death may occur if the correct conversion kits are not installed. The appropriate kits must be applied to ensure safe and proper furnace operation. All conversions must be performed by a qualified installer or service agency.|

    This furnace is shipped from the factory configured for natural gas at standard altitude. Propane gas installations require an orifice change to compensate for the energy content difference between natural and propane gas.

    High altitude installations may require both a pressure switch and an orifice change. These changes are necessary to compensate for the natural reduction in the density of both the gas fuel and the combustion air at higher altitude. Refer to the Accessories Charts in this manual or product Specification Sheet for a tabular listing of appropriate manufacturer’s kits for propane gas and/or high altitude installations. The indicated kits must be used to insure safe and proper furnace operation. All conversions must be performed by a qualified installer, or service agency.

    ######## VENT/FLUE PIPE AND COMBUSTION AIR PIPE

    |WARNING

    | |---| |Failure to follow these instructions can result in bodily injury or death. Carefully read and follow all instructions given in this section.|

    |WARNING

    | |---| |Upon completion of the furnace installation, carefully inspect the entire flue system both inside and outside the furnace to assure it is properly sealed. Leaks in the flue system can result in serious personal injury or death due to exposure to flue products including carbon monoxide.|

    This manual will refer to the pipe that discharges products of combustion to the outdoors as the “vent” pipe or “flue” pipe. The pipe that supplies air for combustion to the furnace will be referred to as the “intake” pipe or “combustion air” pipe.

    A condensing gas furnace achieves its high level of efficiency by extracting almost all of the heat from the products of combustion and cooling them to the point where condensation takes place. Because of the relatively low flue gas temperature and water condensation requirements, PVC pipe is used as venting material.

    This furnace must not be connected to Type B, BW, or L vent or vent connector, and must not be vented into any portion of a factory built or masonry chimney except when used as a pathway for PVC as described later in this section. Never common vent this appliance with another appliance or use a vent which is used by a solid fuel appliance.

    It is the responsibility of the installer to follow the manufacturers’ recommendations and to verify that all vent/flue piping and connectors are compatible with furnace flue products. Additionally, it is the responsibility of the installer to ensure that all piping and connections possess adequate structural integrity and support to prevent flue pipe separation, shifting, or sagging during furnace operation.

    Dual Certification: Non-Direct/Direct Vent (90% Furnaces Only)

    The 90% furnace is dual certified and may be installed as a non-direct vent (single pipe) or direct vent (dual pipe) appliance. A non-direct vent installation requires only a vent/ flue pipe. A direct vent installation requires both a vent/ flue pipe and a combustion air intake pipe. Refer to the appropriate section for details concerning piping size, length, number of elbows, furnace connections, and terminations.

    Page 12

    |WARNING

    | |---| |To avoid bodily injury, fire or explosion, solvent cements must be kept away from all ignition sources (i.e., sparks, open flames, and excessive heat) as they are combustible liquids. Avoid breathing cement vapors or contact with skin and/or eyes.|

    Precautions should be taken to prevent condensate from freezing inside the vent/flue pipe and/or at the vent/flue pipe termination. It is our recommendation that all vent/flue piping exposed to temperatures below 35°F for extended periods of time should be insulated with 1/2” thick closed cell foam. Also all vent/flue piping exposed outdoors in excess of the terminations shown in this manual (or in unheated areas) should be insulated with 1/2” thick closed cell foam. Inspect piping for leaks prior to installing insulation.

    The following bullets and diagram describe the restrictions concerning the appropriate location of vent/flue pipe and combustion air intake pipe (when applicable) terminations. Refer to the installation instructions for specific details on termination construction.

  • • All terminations must be located at least 12 inches above ground level or the anticipated snow level.
  • • Vent terminations must terminate at least 3 feet above any forced air inlet located within 10 feet.
  • • NOTE: This provision does not apply to the combustion air intake termination of a direct vent application.
  • • The vent termination of a non-direct vent application must terminate at least 4 feet below, 4 feet horizontally from, or 1 foot above any door, window, or gravity air inlet into any building.
  • • The vent termination of a direct vent application must terminate at least 12 inches from any opening through which flue gases may enter a building (door, window, or gravity air inlet).
  • • The vent termination of vent pipe run vertically through a roof must terminate at least 12 inches above the roof line (or the anticipated snow level) and be at least 12 inches from any vertical wall (including any anticipated snow build up).
  • • A vent termination shall not terminate over public walkways or over an area where condensate or vapor could create a nuisance or hazard or could be detrimental to the operation of regulators, relief valves, or other equipment.
  • • The combustion air intake termination of a direct vent application should not terminate in an area which is frequently dusty or dirty.
  • NOTE: In Canada, the B149 Fuel Gas Code takes precedence over the preceding termination restrictions.

    ################### Direct Vent Installations

    On upflow units secure the combustion air intake pipe directly to the air intake coupling. On counterflow units secure the combustion air intake pipe to the air intake coupling using the rubber coupling and worm gear hose clamps provided with the unit. The counterflow rubber coupling allows service removal of air intake piping internal to the furnace blower compartment. The combustion air intake pipe can also be secured directly to the counterflow unit air intake pipe coupling.

    ################### Non-Direct Vent Installations

    A minimum of one 90° elbow must be installed on the combustion air intake “coupling” to guard against inadvertent blockage.

    |CAUTION

    | |---| |Edges of sheet metal holes may be sharp. Use gloves a precaution when removing hole plugs.|

    |WARNING

    | |---| |The rubber elbow is not designed to support a load. When the rubber elbow is mounted externally to the furnace cabinet, extreme care must be taken to adequately support field-supplied vent/flue piping, as damage can result in leaks causing bodily injury or death due to exposure to flue gases, including carbon monoxide.|

    |CAUTION

    | |---| |Be sure not to damage internal wiring or other components when reinstalling coupling and screws.|

    ################### Vent/Flue Pipe Lengths and Diameters

    Refer to the following tables for applicable length, elbows, and pipe diameter for construction of the vent/flue pipe system of a non-direct vent installation. In addition to the vent/flue pipe, a single 90° elbow must be secured to the combustion air intake to prevent inadvertent blockage. The tee or elbows used in the vent/flue termination must be included when determining the number of elbows in the piping system.

  • Vent/Flue and Combustion Air Pipe Lengths and Diameters

    Refer to the preceding table for applicable length, elbows, and pipe diameter for construction of the vent/flue and combustion air intake pipe systems of a non-direct vent (single pipe) installation. The number of elbows tabulated represents the number of elbows and/or tees in each (Vent/Flue & Combustion Air Intake) pipe. Elbows and/or tees used in the terminations must be included when determining the

    number of elbows in the piping systems. If the combustion air intake pipe is to be installed above a finished ceiling or other area where dripping of condensate will be objectionable, insulation of the combustion air pipe may be required. Use 1/2” thick closed cell foam insulation such as Armaflex or Insultube where required.

    Vent/Flue Pipe Terminations The vent/flue pipe may terminate vertically, as through a roof, or horizontally, as through an outside wall.

    Vertical vent/flue pipe termination should be as shown in the following figures. Refer to Vent/Flue Pipe and Combustion Air Pipe - Termination Locations section in this manual or the installation instructions for details concerning location restrictions. The penetration of the vent through the roof must be sealed tight with proper flashing such as is used with a plastic plumbing vent.

    NOTE: Terminate both pipes in the same pressure zone (same side of roof, no major obstacles between pipes, etc.).

    In a basement installation, the vent/flue pipe can be run between joist spaces. If the vent pipe must go below a joist and then up into the last joist space to penetrate the header, two 45° elbows should be used to reach the header rather than two 90° elbows.

    ################### Direct Vent (Dual Pipe) Piping

    Page 16

    Direct vent installations require both a combustion air intake and a vent/flue pipe. The pipes may be run horizontally and exit through the side of the building or run vertically and exit through the roof of the building. The pipes may be run through an existing unused chimney; however, they must extend a minimum of 12 inches above the top of the chimney. The space between the pipes and the chimney must be closed with a weather tight, corrosion resistant flashing. Both the combustion air intake and a vent/flue pipe terminations must be in the same atmospheric pressure zone. Refer to Vent/Flue and Combustion Air Pipe - Termination Locations or Concentric Vent Termination section in this manual or the installation instructions for specific details on termination construction.

    ################### Concentric Vent Kits Application

    The Concentric Vent Kits are designed to allow the terminations of a direct vent furnace to be “concentrically” vented through a wall or roof. This kit allows a single penetration to support terminations for both the vent/flue pipe and the combustion air intake pipe.

    |WARNING

    | |---| |Do not operate the furnace with the rain cap removed as recirculation of the flue gases may occur. Water may also collect inside the larger combustion air pipe and flow to the burner enclosure. Failure to follow this warning can result in property damage, equipment damage, personal injury or death.|

    ################### Concentric Sidewall Vent Kit (0170K00000S)

    This (sidewall only) vent kit is to be used with 2” - 3” vent systems. The vent kit must terminate outside the structure and may be installed with the intake and exhaust pipes located side-by side or with one pipe above the other. This kit is NOT intended for use with single pipe (non-direct vent) installations.

    ######## CONDENSATE DRAIN LINES AND DRAIN TRAP

    A condensing gas furnace achieves its high level of efficiency by extracting almost all of the heat from the products of combustion and cooling them to the point where condensation takes place. The condensate which is generated must be piped to an appropriate drain location.

    |WARNING

    | |---| |In upright upflow installations, the drain trap must be mounted on the opposite side of the unit from the junction box. This will reduce the risk of water reaching the junction box in the event of a blocked drain condition. Failure to follow the these instructions can result in possible property damage, personal injury, or death due to electrical shock.|

  • • If the drain line is routed through an area which may see temperatures near or below freezing, precautions must be taken to prevent condensate from freezing within the drain line.
  • • If an air conditioning coil is installed with the furnace, a common drain may be used. An open tee must be installed in the drain line, near the cooling coil, to relieve positive air pressure from the coil’s plenum. This is necessary to prohibit any interference with the function of the furnace’s drain trap.
  • Page 18

    Drain Information for Horizontal Installations NOTE: Horizontal installations require 5.5” under the furnace to accommodate the drain trap. The horizontal furnace must be installed with ¾” slope from back to front to permit condensate flow towards the front of the furnace.

    When installing a *M9S9* horizontally with the left side down, there are two options for connecting the vent pipe to the furnace.

    Option 1 Venting may be connected to the furnace vent pipe fitting on the original top (now the end) of the furnace.

    Option 2

    The internal vent pipe and elbow may be removed from the furnace to permit the vent to exit the top (original side) of the furnace. If this option is used, an RF000142 Vent-Drain coupling must be used to keep condensate from collecting in the inducer assembly.

    To install the drain, refer to the following instructions and illustration.

    COMBUSTION AIR INTAKE PIPE OPTIONS: The RF000142 coupling can be secured directly to the furnace intake coupling if condensation is occurring in the combustion air inlet pipe. If the RF000142 is used on the combustion air inlet, it must be installed with the arrow pointing up. It should be noted, the combustion air will actually be moving in a direction opposite of the arrow on the RF000142 coupling.

    Alternatively a tee may be used in the combustion air intake pipe for the same purpose. If either option is used, a field supplied trapped drain tube, free-draining to proper condensate disposal location must be present. A loop in the drain tube can serve as a trap. The unused RF000142 drain fitting should be capped.

  • 1. Remove screws from vent flange.
  • 2. Remove internal elbow and vent pipe.
  • 3. Cut pipe 2 1/2” from flange.
  • 4. Remove cabinet plug adjacent to inducer outlet and install an original cabinet vent hole.
  • 5. Install RF000142 coupling on inducer outlet.
  • 6. Install flanged vent section removed in step 2 and secure with clamps.
  • 7. Secure flange to cabinet using screws removed in step 1.
  • Insert flange. Cut 2 ½” long. R 000142F

    ######## GAS SUPPLY AND PIPING

    The furnace rating plate includes the approved furnace gas input rating and gas types. The furnace must be equipped to operate on the type of gas applied. This includes any conversion kits required for alternate fuels and/or high altitude.

    |CAUTION

    | |---| |To prevent unreliable operation or equipment damage, the inlet gas supply pressure must be as specified on the unit rating plate with all other household gas fired appliances operating.|

    Inlet gas supply pressures must be maintained within the ranges specified below. The supply pressure must be constant and available with all other household gas fired appliances operating. The minimum gas supply pressure must be maintained to prevent unreliable ignition. The maximum must not be exceeded to prevent unit overfiring.

    |INLET GAS SUPPLY PRESSURE|INLET GAS SUPPLY PRESSURE|INLET GAS SUPPLY PRESSURE| |---|---|---| |Natural Gas|Minimum: 4.5" w.c.|Maximum: 10.0" w.c.| |Propane Gas|Minimum: 11.0" w.c.|Maximum: 13.0" w.c.|

    ################### High Altitude Derate

    When this furnace is installed at high altitude, the appropriate High Altitude orifice kit must be applied. This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range.

    Page 19

    High altitude kits are purchased according to the installation altitude and usage of either natural or propane gas. Refer to the product Specification Sheet or the Accessory Matrix in this Manual for a tabular listing of appropriate altitude ranges and corresponding manufacturer’s high altitude (Natural, Propane gas, and/or Pressure Switch) kits.

    Do not derate the furnace by adjusting the manifold pressure to a lower pressure than specified on the furnace rating plate. The combination of the lower air density and a lower manifold pressure will prohibit the burner orifice from drawing the proper amount of air into the burner. This may cause incomplete combustion, flashback, and possible yellow tipping.

    In some areas the gas supplier may artificially derate the gas in an effort to compensate for the effects of altitude. If the gas is artificially derated, the appropriate orifice size must be determined based upon the BTU/ft3 content of the derated gas and the altitude. Refer to the National Fuel Gas Code, NFPA 54/ANSI Z223.1, and information provided by the gas supplier to determine the proper orifice size.

    A different pressure switch may be required at high altitude regardless of the BTU/ft3 content of the fuel used. Refer to the product Specification Sheet or Technical Manual for a tabular listing of appropriate altitude ranges and corresponding manufacturer’s pressure switch kits.

    ######## PROPANE GAS CONVERSION

    |WARNING

    | |---| |Possible property damage, personal injury or death may occur if the correct conversion kits are not installed. The appropriate kits must be applied tot ensure safe and proper furnace operation. All conversions must be performed by a qualified installer or service agency.|

    This unit is configured for natural gas. The appropriate manufacturer’s propane gas conversion kit, must be applied for propane gas installations.

    **9S9* models using a White-Rodgers 36J22 single stage valve use LPM-07 LP Conversion Kit.

    ######## GAS VALVE

    This unit is equipped with a 24 volt gas valve controlled during furnace operation by the integrated control module. As shipped, the valve is configured for natural gas. The valve is field convertible for use with propane gas by using the appropriate propane gas conversion kit. Taps for measuring the gas supply pressure and manifold pressure are provided on the valve.

    NOTE: The gas supply pressure on White-Rodgers “J” model gas valve, used on single stage furnaces, can be checked with a gas pressure test kit (Part #0151K00000S) available through our authorized distributors.

    The gas valve has a manual ON/OFF control located on the valve itself. This control may be set only to the “ON” or “OFF” position. Refer to the Lighting Instructions Label or the “Putting the Furnace Into Operation” section of this manual or the installation instructions for use of this control during start up and shut down periods.

    ################### Gas Piping Connections

    |WARNING

    | |---| |To avoid possible unsatisfactory operation of equipment damage due to underfiring or equipment, use the proper size of natural/propane gas piping needed when running pipe from the meter/tank furnace.|

    The gas piping supplying the furnace must be properly sized based on the gas flow required, specific gravity of the gas, and length of the run. The gas line installation must comply with local codes, or in their absence, with the latest edition of the National Fuel Gas Code, NFPA 54/ANSI Z223.1.

    To connect the furnace to the building’s gas piping, the installer must supply a ground joint union, drip leg, manual shutoff valve, and line and fittings to connect to gas valve. In some cases, the installer may also need to supply a transition piece from 1/2” pipe to a larger pipe size.

    The following stipulations apply when connecting gas piping. Refer to the following figures for typical gas line connections to the furnace.

  • 1. Use black iron or steel pipe and fittings for the building piping.
  • 2. Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used.
  • 3. Use ground joint unions.
  • 4. Install a drip leg to trap dirt and moisture before it can enter the gas valve. The drip leg must be a minimum of three inches long.
  • 5. Install a 1/8” NPT pipe plug fitting, accessible for test gage connection, immediately upstream of the gas supply connection to the furnace.
  • 6. Use two pipe wrenches when making connection to the gas valve to keep it from turning. The orientation of the gas valve on the manifold must be maintained as shipped from the factory.
  • 7. Install a manual shutoff valve between the gas meter and unit within six feet of the unit. If a union is installed, the union must be downstream of the manual shutoff valve, between the shutoff valve and the furnace.
  • 8. Tighten all joints securely.
  • GAS PIPING CHECKS Before placing unit in operation, leak test the unit and gas connections.

    |WARNING

    | |---| |To avoid possibility of explosion or fire, never use a match or open flame to test for leaks.|

    Check for leaks using an approved chloride-free soap and water solution, an electronic combustible gas detector, or other approved testing methods.

    NOTE: Never exceed specified pressures for testing. Higher pressure may damage the gas valve and cause subsequent overfiring, resulting in heat exchanger failure. Disconnect this unit and shutoff valve from the gas supply piping system before pressure testing the supply piping system with pressures in excess of 1/2 psig (3.48 kPa). Isolate this unit from the gas supply piping system by closing its external manual gas shutoff valve before pressure testing supply piping system with test pressures equal to or less than 1/2 psig (3.48 kPa).

    ######## PROPANE GAS TANKS AND PIPING

    |WARNING

    | |---| |Propane gas is heavier than air and any leaking gas can settle in any low areas or confined spaces. To prevent property damage, personal injury, or death to fire or explosion caused by a propane gas leak, install a gas detection warning device.|

    A gas detecting warning system is the only reliable way to detect a propane gas leak. Iron oxide (rust) can reduce the level of odorant in propane gas. Do not rely on your sense of smell. Contact a local propane gas supplier about installing a gas detecting warning system. If the presence of gas is suspected, follow the instructions on this page.

    All propane gas equipment must conform to the safety standards of the National Board of Fire Underwriters, NBFU Manual 58.

    For satisfactory operation, propane gas pressure must be 10 inch WC at the furnace manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors:

  • 1. Vaporization rate, depending on temperature of the liquid, and “wetted surface” area of the container or containers.
  • 2. Proper pressure regulation (Two-stage regulation is recommended for both cost and efficiency).
  • Pressure drop in lines between regulators, and between second stage regulator and the appliance. Pipe size will depend on length of pipe run and total load of all appliances.
  • Page 21

    Complete information regarding tank sizing for vaporization, recommended regulator settings, and pipe sizing is available from most regulator manufacturers and propane gas suppliers.

    Use pipe dope approved for use with L.P. gas. Refer to the following illustration for typical propane gas installations and piping.

    Typical Propane Gas Installation

    |WARNING

    | |---| |If the gas furnace is installed in a basement, an excavated area or confined space, it is strongly recommended to contact a propane supplier to install a gas detecting warning device in case of a gas leak.

    • Since propane gas is heavier than air, any leaking gas can settle in any low areas or confined spaces.
    • Propane gas odorant may fade, making the gas undetectable except with a warning device.
    |

    |WARNING

    | |---| |An undetected gas leak will create a danger of explosion or fire. If the presence of gas is suspected, follow the instructions on the cover of this manual. Failure to do so could result in SERIOUS PERSONAL INJURY OR DEATH.|

    |WARNING

    | |---| |If the information in these instructions is not followed exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

    - do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
    - WHAT TO DO IF YOU SMELL GAS:

    • Do not try to light any appliance.
    • Do not touch any electrical switch; do not use any phone in your building.
    • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. If you cannot reach your gas supplier, call the fire department.


    - Installation and service must be performed by a qualified installer, service agency or the gas supplier.

    ######################### Propane Gas Piping Charts

    When installing a propane storage tank, the contractor must consider proper tank sizing, safety, efficiency, ground characteristics and aesthetics. For a residential customer, the size may range from 100-1,000 gallons, depending on household use. Typically, a 500 gallon tank is ample for an average four-bedroom home. However, it is best to consult your local propane supplier to ensure the proper sizing for propane storage requirements. Determining the correct tank size for each household is a function of demand, economy, efficiency and convenience. It is a process that requires cooperation between the propane supplier and customer.

To make electrical connections through the opposite side of the furnace, the junction box must be relocated to the left side prior to making electrical connections. To relocate the junction box, perform the following steps.

  • Remove the burner compartment door.
  • 2. Remove and save the two screws securing the junction box to the side panel.
  • 3. Relocate junction box and associated plugs and grommets to opposite side panel. Secure with screws removed in step.
  • IMPORTANT NOTE: Wire routing must not interfere with circulator blower operation, filter removal or routine maintenance.

    To ensure proper unit grounding, the ground wire should run from the furnace ground screw located inside the furnace junction box all the way back to the electrical panel.

    NOTE: Do not use gas piping as an electrical ground. To confirm proper unit grounding, turn off the electrical power and perform the following check.

  • Measure resistance between the neutral (white) connection and one of the burners. Resistance should measure 10 ohms or less.
  • This furnace is equipped with a blower door interlock switch which interrupts unit voltage when the blower door is opened for servicing. Do not defeat this switch.

    24 Volt Thermostat Wiring IMPORTANT NOTE: Wiring routing must not interfere with circulator blower operation, filter removal or routine maintenance.

    Low voltage connections can be made through either the right or left side panel. Thermostat wiring entrance holes are located in the blower compartment. The following figure shows connections for a “heat/cool system”.

    This furnace is equipped with a 40 VA transformer to facilitate use with most cooling equipment. Consult the wiring diagram, located on the blower compartment door, for further details of 115 Volt and 24 Volt wiring.

    ################### Fossil Fuel Applications

    This furnace can be used in conjunction with a heat pump in a fossil fuel application. A fossil fuel application refers to a combined gas furnace and heat pump installation which uses an outdoor temperature sensor to determine the most cost efficient means of heating (heat pump or gas furnace).

    A heat pump thermostat is required to properly use a single-stage furnace in conjunction with a heat pump. Refer to the fossil fuel kit installation instructions for additional thermostat requirements.

    Strictly follow the wiring guidelines in the fossil fuel kit installation instructions. All furnace connections must be made to the furnace two-stage integrated control module and the “FURNACE” terminal strip on the fossil fuel control board.

    ################### Twinning

    Two furnaces of the same model may be twinned. The integrated control board has a 3/16” terminal labeled “TWIN” located beside the low voltage thermostat connection strip. Twinning allows simultaneous operation of two furnaces and forces the indoor blower motors of each furnace to operate synchronously into a common duct system. Using the twinning function will require only field installed wiring with no external kits or parts. The staging and speed tap options must be set the same on both furnaces.

    NOTE: Each furnace must be connected to it’s own 115 VAC power supply. The L1 connection to each furnace must be in phase (connected to circuit breakers on the same 115 VAC service panel phase leg). To verify that the furnaces are in phase, check from L1 to L1 on each furnace with a voltmeter. If the furnaces are in phase, the voltage between both furnaces will be ZERO.

    | |---| |HIGH VOLTAGE Disconnect ALL power before servicing or changing any electrical wiring. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.|

    ######## MAINTENANCE

    Improper filter maintenance is the most common cause of inadequate heating or cooling performance. Filters should be cleaned (permanent) or replaced (disposable) every two months or as required. It is the owner’s responsibility to keep air filters clean. When replacing a filter, it must be replaced with a filter of the same type and size.

    ######## FILTER REMOVAL

    Depending on the installation, differing filter arrangements can be applied. Filters can be installed in the central return register, the bottom of the blower compartment (upflow only), a side panel external filter rack kit (upflow only), or the ductwork above a counterflow furnace. A media air filter or electronic air cleaner can be used as an alternate filter. The filter sizes given in the Product Design section of this manual or the product Specification Sheet must be followed to ensure proper unit performance. Refer to the following information for removal and installation of filters.

    ######## FILTER REMOVAL PROCEDURE

    ######## FLAME SENSOR (QUALIFIED SERVICER ONLY)

    Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator, causing a drop in the flame sensing signal. If this occurs, a qualified servicer must carefully clean the flame sensor with steel wool. After cleaning, the flame sensor output should be as listed on the specification sheet.

    ######## BURNERS

    |WARNING

    | |---| |HIGH VOLTAGE Electrical components are contained in both compartments. To avoid electrical shock, injury or death, do not remove any internal compartment covers or attempt any adjustment. Contact a qualified service agent at once if an abnormal flame appearance should develop.|

    Page 30

    Periodically during the heating season make a visual check of the burner flames. Turn the furnace on at the thermostat. Wait a few minutes since any dislodged dust will alter the normal flame appearance. Flames should be stable, quiet, soft and blue with slightly orange tips. They should not be yellow. They should extend directly outward from the burner ports without curling downward, floating or lifting off the ports.

    ################### Media Air Filter or Electronic Air Cleaner Removal Follow the manufacturer’s directions for service.

    Horizontal Unit Filter Removal Filters in horizontal installations are located in the central return register.

    Check the burner flames for:

  • 1. Stable, soft and blue
  • 2. Not curling, floating, or lifting off.
  • ######## INDUCED DRAFT AND CIRCULATION BLOWERS

    The bearings in the induced draft blower and circulator blower motors are permanently lubricated by the manufacturer. No further lubrication is required. Check motor windings for accumulation of dust which may cause overheating. Clean as necessary.

    ######## CONDENSATE DRAINAGE SYSTEM (QUALIFIED SERVICER ONLY)

    The drain tubes, standpipe, and field supplied drain line must be checked annually and cleaned as often as necessary to ensure proper condensate drainage.

    TEST EQUIPMENT Proper test equipment for accurate diagnosis is as essential as regular hand tools.

    The following is a must for every service technician and service shop.

  • 1. Thermometers or thermocouple meter (optional) - To measure temperatures.
  • 2. Multi-Meter - To measure amperage and voltage, and to test continuity, capacitors and motor windings.
  • 3. Manometer - To measure static pressure, pressure drop across coils, filters and draft, and to measure inlet and manifold gas pressures.
  • Other recording type instruments can be essential in solving abnormal problems, however, in many instances they may be rented from local sources.

    Proper equipment promotes faster, more efficient service and accurate repairs resulting in fewer call backs.

    ################### HEATING PERFORMANCE TEST

    Before attempting to diagnose an operating fault code, run a Heating Performance Test to determine if the heating system is performing within 5% of the BTU input found on the rating plate of the unit being tested. To conduct a heating performance test, the BTU input to the unit must be calculated (see Clocking a Gas Meter). Before clocking a gas meter, contact your local utility to provide the caloric value (BTU content) of the natural gas in the area.

    It is also important to confirm the airflow (CFM) is within the temperature rise range (see Airflow Data in spec sheet) and external static pressure range (approximately 0.5” water column). How-to instructions can be found in the service manual under Checking External Static Pressure and Checking Temperature Rise.

    ################### CLOCKING A GAS METER

  • 1. Turn off all gas appliances in the home.
  • 2. Turn on the furnace. Ensure the furnace is operating at a 100% firing rate on 2 stage and modulating furnace product.
  • 3. Once heating cycle is at a steady state (typically 15 minutes of operation), use a stopwatch to time how long it takes the smallest unit of measure dial on the gas meter to make a full revolution. In Table 1, one cubic foot is selected. The smallest unit of measure will vary depending on the gas meter.

    TABLE 2

  • 5. Use this formula to verify the Cubic Feet per Hour (CFH) input determined in step 4 is correct: (3600 x Gas Meter Dial Size) / Time (seconds) = Cubic Feet per Hour (CFH)
  • 3600 is used as there are 60 seconds in a minute and 60 minutes in an hour. 60x60=3600

    Page 32

  • 6. Check with your local utility for actual BTU content (caloric value) of natural gas in the area (the average is 1025 BTU’s).
  • 7. Use this formula to calculate the BTU/HR input (See BTU/HR Calculation Example): Cubic Feet per Hour (CFH) x BTU content of your natural gas = BTU/HR input
  • 8. Should the figure you calculated not fall within five (5) percent of the nameplate rating of the unit, adjust the gas valve pressure regulator or resize orifices. To adjust the pressure regulator on the gas valve, turn downward (clockwise) to increase pressure and input, and upward (counterclockwise) to decrease pressure and input. A properly operating unit must have the BTU per hour input and CFM of air, within the limits shown to prevent short cycling of the equipment. As the external static pressure goes up, the temperature rise will also increase. Consult the proper tables for temperature rise limitation.
  • ################### BTU/HR Calculation Example:

    The unit being tested takes 40 seconds for the 1 cubic foot dial to make one complete revolution. Using the chart, this translates to 90 cubic feet per hour. Based upon the assumption that one cubic foot of natural gas has 1,025 BTU’s (Check with your local utility for actual BTU content), the calculated input is 92,250 BTU’s per hour.

    Furnace Nameplate Input in this example: 90,000 BTU/HR Calculated Gas Input in this example: 92,250 BTU/HR This example is within the 5% tolerance input and does not need adjustment.

    |CAUTION

    | |---| |Always connect a manometer to the outlet tap at the gas valve before adjusting the pressure regulator. In no case should the final manifold pressure vary more than plus or minus .2 inches water column from 3 inches water column for natural gas.|

    A properly operating unit must have the BTU per hour input and CFM of air, within the limits shown to prevent short cycling of the equipment. As the external static pressure goes up, the temperature rise will also increase. Consult the proper tables for temperature rise limitation.

    |CAUTION

    | |---| |Always connect a manometer to the outlet tap at the gas valve before adjusting the pressure regulator. In no case should the final manifold pressure vary more than plus or minus .3 inches water column from 3.5 inches water column for natural gas or 10 inches water column for propane gas.|

    Since normally propane gas is not installed with a gas meter, clocking will be virtually impossible. The gas orifices used with propane are calculated for 2500 BTU per cubic foot gas and with proper inlet pressures and correct piping size, full capacity will be obtained.

    With propane gas, no unit gas valve regulator is used; however, the second stage supply line pressure regulator should be adjusted to give 10” water column with all other gas consuming appliances running.

    The dissipation of the heat transferred to the heat exchanger is now controlled by the amount of air circulated over its surface.

    The amount (CFM) of air circulated is governed by the external static pressure in inches of water column of duct work, cooling coil, registers, etc., applied externally to the unit versus the motor speed tap (direct drive) or pulley adjustments of the motor and blower (belt drive).

    A properly operating unit must have the BTU per hour input and CFM of air, within the limits shown to prevent short cycling of the equipment. As the external static pressure goes up, the temperature rise will also increase. Consult the proper tables for temperature rise limitation.

    As more and more electronics are introduced to the Heating Trade, Polarization of incoming power and phasing of primary to secondary voltage on transformers becomes more important.

    Polarization has been apparent in the Appliance industry since the introduction of the three prong plug, however, the Heating Industry does not use a plug for incoming power, but is hard wired.

    Some of the electronic boards being used today, with flame rectification, will not function properly and/or at all without polarization of incoming power. Some also require phasing between the primary and secondary sides of step-down transformers.

    We recommend that these two items be checked during normal installation and/or service calls. See as follows:

    |WARNING

    | |---| |Disconnect ALL power before servicing.|

  • 1. Remove blower compartment door to gain access to the circulator blower motor and integrated ignition control.
  • 2. Check for any obstruction that would keep the fan wheel / fan motor from turning.
  • Check wiring, the motor has two wiring harnesses, a main harness and a control harness. The main pin harness has: White neutral wire connected to the Neutral terminal on the control board. Black wire connected to the CIRC H terminal on the control board. Red wire connected to the COM terminal, which is a female spade connection next to the T1 – T5.

    ################ CHECKING DUCT STATIC

    The maximum and minimum allowable external static pressures are found in the specification section. These tables also show the amount of air being delivered at a given static by a given motor speed or pulley adjustment.

    The furnace motor cannot deliver proper air quantities (CFM) against statics other than those listed.

    Too great of an external static pressure will result in insufficient air that can cause excessive temperature rise, resulting in limit tripping, etc. Whereas not enough static may result in motor overloading.

    To determine proper air movement, proceed as follows:

  • 1. With clean filters in the furnace, use a manometer to measure the static pressure of the return duct at the inlet of the furnace. (Negative Pressure)
  • Page 38

  • 2. Measure the static pressure of the supply duct. (Positive Pressure)
  • 3. Add the two (2) readings together for total external static pressure.
  • NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired. If an air conditioner coil or Electronic Air Cleaner is used in conjunction with the furnace, the readings must also include theses components, as shown in the following drawing.

  • Consult proper tables for the quantity of air.
  • If the total external static pressure exceeds the minimum or maximum allowable statics, check for closed dampers, registers, undersized and/or oversized poorly laid out duct work.

    ![image 10](90_20GM9S_20GC9S_20Service_20Manual_images/imageFile10.png)

    ########## .

    ################ Checking Static Pressure CHECKING TEMPERATURE RISE

    The more air (CFM) being delivered through a given furnace, the less the rise will be; so the less air (CFM) being delivered, the greater the rise. The temperature rise should be adjusted in accordance to a given furnace specifications and its external static pressure. An incorrect temperature rise may result in condensing in or overheating of the heat exchanger. An airflow and temperature rise table is provided in the blower performance specification section. Determine and adjust temperature rise as follows:

  • Operate furnace with burners firing for approximately ten minutes. Check BTU input to furnace - do not exceed input rating stamped on rating plate. Ensure all registers are open and all duct dampers are in their final (fully or partially open) position.
  • 2. Place thermometers in the return and supply ducts as close to the furnace as possible. Thermometers must not be influenced by radiant heat by being able to “see” the heat exchanger.
  • SUPPLY AIR

    RETURN AIR

    Checking Temperature Rise

  • 3. Subtract the return air temperature from the supply air temperature to determine the air temperature rise. Allow adequate time for thermometer readings to stabilize.
  • 4. Adjust temperature rise by adjusting the circulator blower speed. Increase blower speed to reduce temperature rise. Decrease blower speed to increase temperature rise. Refer to Circulator Blower Speed section in the Product Design section of this manual for speed changing details. Temperature rise is related to the BTUH output of the furnace and the amount of air (CFM) circulated over the heat exchanger. Measure motor current draw to determine that the motor is not overloaded during adjustments.

    ################ CHECKING HOT SURFACE IGNITOR

    Single stage furnaces use a 115 volt silicon carbide igniter (p/n 0130F00008) with 17-second warm up time.

    |WARNING

    | |---|

    Page 47

    |Disconnect ALL power before servicing.|

  • 1. Remove burner compartment door to gain access to the ignitor.
  • 2. Ignitor cool - approximately 70 - 77°F.
  • 3. Disconnect the ignitor from the Ignition Control.
  • 4. Using an ohmmeter measure the resistance of the ignitor: at room temperature a normal reading will be 37 - 68 ohms.
  • 5. Reconnect ignitor.
  • |WARNING

    | |---| |Line Voltage now present.|

  • 6. Place unit in heating cycle, measure current draw of ignitor during preheat cycle.
  • ################ CHECKING FOR FLASHBACK

    Flashback will also cause burning in the burner venturi, but is caused by the burning speed being greater than the gasair flow velocity coming from a burner port.

    Flashback may occur at the moment of ignition, after a burner heats up or when the burner turns off. The latter is known as extinction pop.

    Since the end results of flashback and delayed ignition can be the same (burning in the burner venturi) a definite attempt should be made to determine which has occurred.

    If flashback should occur, check for the following:

  • 1. Improper gas pressure - adjust to proper pressure (See CHECKING GAS PRESSURE).
  • 2. Check burner for proper alignment and/or replace burner.
  • 3. Improper orifice size - check orifice for obstruction.
  • ################ CHECKING PRESSURE SWITCH

    The pressure control is a safety device to prevent the combustion cycle from occurring with inadequate venting caused by a restricted or blocked vent pipe.

    |WARNING

    | |---| |HIGH VOLTAGE Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.|

  • 1. Remove burner compartment door to gain access to pressure switch(es).
  • 2. Remove wires from the pressure switch(es) electrical terminals.
  • 3. Remove the pressure control hose from the control and interconnect with a manometer as shown in the following figures.
  • With a call for heat and the inducer running, check across the pressure switch contacts with an ohm meter. If the contacts are not closed, compare the negative reading on the manometer with the rating on the pressure switch to determine whether the switch is defective or if the negative pressure is inadequate to close the switch.

    ################ HIGH ALTITUDE APPLICATION (USA)

    A high altitude kit is required for installations above 7,000 ft. Refer to the accessory matrix in this manual to determine the proper natural gas and LP gas high altitude kit for your furnace.

    ################ CHECKING FOR DELAYED IGNITION

    Delayed ignition is a delay in lighting a combustible mixture of gas and air which has accumulated in the combustion chamber.

    Furnace design makes this extremely unlikely unless safety controls have been by-passed or tampered with. Never bypass or alter furnace controls.

    If delayed ignition should occur, the following should be checked:

  • Improper gas pressure - adjust to proper pressure (See CHECKING GAS PRESSURE).
  • 2. Improper burner positioning - burners should be in locating slots, level front to rear and left to right.
  • 3. Carry over (lighter tube or cross lighter) obstructed clean.
  • 4. Main burner orifice(s) deformed, or out of alignment to burner - replace.
  • ################ CHECKING INTEGRATED IGNITION CONTROL BOARDS

    NOTE: Failure to earth ground the furnace, reversing the neutral and hot wire connection to the line (polarity), or a high resistance connection in the neutral line may cause the control to lockout due to failure to sense flame.

    |WARNING

    | |---| |To avoid the risk of electrical shock, wiring to the unit must be properly polarized and grounded. Disconnect power before performing service listed below.|

    The ground wire must run from the furnace all the way back to the electrical panel. Proper grounding can be confirmed by disconnecting the electrical power and measuring resistance between the neutral (white) connection and the burner closest to the flame sensor. Resistance should be less than 2 ohms.

    The ignition control is a combination electronic and electromechanical device and is not field repairable. Complete unit must be replaced.

    |WARNING

    |

    Page 49

    |---| |Line Voltage now present.|

    These tests must be completed within a given time frame due to the operation of the ignition control.

    The ignition control is capable of diagnosing many furnace failures to help in troubleshooting. The trial for ignition period is 4 seconds.

    The indicator light/display may be viewed by looking through the sight glass in the blower compartment door. If the blower compartment door is removed, failure to hold the door switch closed while removing the blower compartment door will result in the loss of the stored failure code. In most cases recycling the ignition control will result in the same failure code originally displayed.

    |WARNING

    | |---| |Line Voltage now present.|

    These tests must be completed within a given time frame due to the operation of the ignition control.

  • 1. Check for 120 volts from Line 1 (Hot) to Line 2 (Neutral) at the ignition control. No voltage, check the door switch connections and wire harness for continuity.
  • 2. Check for 24 volts from W to C terminal on the ignition control. No voltage. Check transformer, room thermostat, and wiring. If you have 24 volts coming off the transformer but receive approximately 13 volts on the terminal board between (C) and (R), check for blown fuse.
  • 3. Check for 120 volts to the induced draft blower by measuring voltage between Pin 1 (on the 2-pin connector) and Line (Neutral) on the control board. No voltage, replace ignition control.
  • 4. If voltage is present in Steps 1 through 3 and the induced draft blower is operating, check for 120 volts to the ignitor during the preheat cycle. Measure voltage between Pin 2 (on the 2-pin connector) and Line (Neutral) on the control board. No voltage, check pressure switch.
  • 5. After the ignitor warm-up time, begin checking for 24 volts to the gas valve. Voltage will be present for seven seconds only if proof of flame has been established.
  • ################ CHECKING FLAME SENSOR

    A flame sensing device is used in conjunction with the ignition control module to prove combustion. If proof of flame is not present the control will de-energize the gas valve and “retry” for ignition or lockout.

    |WARNING

    | |---| |HIGH VOLTAGE Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.|

  • 1. Connect a micro-amp meter in series with this wire and the sensor terminal.
  • 2. Be sure the positive side of the meter is to the sensor (depending on the model) and the negative side of the meter is to sensor terminal.
  • |WARNING

    | |---| |Line Voltage now present.|

  • 3. Place the unit into a heating cycle.
  • 4. As soon as flame is established a micro-amp reading should be evident once proof of flame (micro-amp reading) is established, the hot surface ignitor will be de-energized.
  • 5. The Integrated Ignition controls will have 1 to 4 micro-amps. If the micro-amp reading is less than the minimum specified, check for high resistance wiring connections, sensor to burner gap, dirty flame sensor, or poor grounding.
  • 6. If absolutely no reading, check for continuity on all components and if good - replace ignition control module.
  • NOTE: Contaminated fuel or combustion air can create a nearly invisible coating on the flame sensor. This coating works as an insulator causing a loss in the flame sense signal. If this situation occurs the flame sensor must be cleaned with steel wool.

    |WARNING

    |HIGH VOLTAGE Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.|

    |CAUTION

    | |---| |If you must handle the igniter, handle with care. Touching the igniter body with bare fingers, rough handling, or vibration could result in early ingitor failure. Only a qualified servicer should ever handle the igniter.|

    ################ ANNUAL INSPECTION

    The furnace should be inspected by a qualified installer, or service agency at least once per year. This check should be performed at the beginning of the heating season. This will ensure that all furnace components are in proper working order and that the heating system functions appropriately. Pay particular attention to the following items. Repair or service as necessary.

  • • Flue pipe system. Check for blockage and/or leakage. Check the outside termination and the connections at and internal to the furnace.
  • • Combustion air intake pipe system (where applicable). Check for blockage and/or leakage. Check the outside termination and the connection at the furnace.
  • • Heat exchanger. Check for corrosion and/or buildup within the heat exchanger passageways.
  • • Burners. Check for proper ignition, burner flame, and flame sense.
  • • Drainage system. Check for blockage and/or leakage. Check hose connections at and internal to furnace.
  • • Wiring. Check electrical connections for tightness and/ or corrosion. Check wires for damage.
  • • Filters. AIR FILTER
  • |WARNING

    | |---| |Never operate furnace without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage, and possible fire.|

    Filters must be used with this furnace. Filters do not ship with these furnaces but must be provided by the installer for proper furnace operation.

    Remember that dirty filters are the most common cause of inadequate heating or cooling performance.
