What is the maximum vent run length for this dryer?

The maximum vent run length depends on the type of vent and number of 90° elbows used. For example, with rigid metal vent and box or louvered hoods with 0 elbows, the maximum is 64 ft (20 m), but with 4 elbows, it reduces to 27 ft (8.2 m). Refer to the Vent system chart in the installation instructions for your specific configuration. (Page 16)
