Calculating Vent System Length

It is recommended that you use round vent instead of rectangular vent, especially if elbows are required. If rectangular vent is required, it should be transitioned to 10" (25.4 cm) round vent as soon as possible.

The following example falls within the maximum vent length of 40 ft (12.2 m).

2 - 90° elbows

= 10.0 ft (3 m)

10 ft (3 m) straight

= 10.0 ft (3 m)

 

 

Length of 10" (25.4 cm) system

= 20 ft (6 m)

 

 

NOTE: The exterior-mounted vent motor requires a separate wiring cable that should be installed at the same time the vent work is installed.
