How do I inspect the combustion area and vent system?
Turn off gas and electricity, remove the main door to access the burner enclosure front where you can inspect the combustion air and vent PVC pipes for sags, holes, cracks, or disconnections. Reassemble and start the furnace as described on pages 8-9 if no issues are found.
