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.

Determining the length of system you need:

To calculate the length of system you need, add the equivalent feet for each duct piece that will be needed. See example for 10"

(25.4 cm) round vent system.

Vent length is given as a general reference only. For a longer vent run, or smaller vent system, contact a qualified and trained vent installer. Check with local codes for makeup air requirements, if any.

For best performance, use no more

than three 90° elbows. If more than

Built-in cabinet location one elbow is used, make sure that there is a minimum of 24 inches

(61 cm) of straight vent between any two elbows. Do not install two elbows together.

Maximum length = 40 ft. (12.2 m)

2 - 90 elbows	= 10	ft. (3.05 m)
10 ft. (3 m) straight	= 10	ft. (3.05 m)

Length of 10"
(25.4 cm) system	= 20 ft. (6.1 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.
