Recommended Vent Length

A 3

¹⁄₄

"

 x 10

"

 (8.3 x 25.4 cm) rectangular or 6

"

 (15.2 cm) round vent 

should be used.
The total length of the vent system including straight vent, 
elbow(s), transitions and wall or roof caps must not exceed the 
equivalent of 140 ft (42.7 m) for either type of vent. See 
“Recommended Standard Fittings” section for equivalent lengths.
For best performance, use no more than three 90° elbows.
To calculate the length of the system you need, add the equivalent 
lengths of each vent piece used in the system. See the following 
examples:

" x 10" (8.3 x 25.4 cm) vent system = 73 ft (22.2 m) total

6" (15.2 cm) vent system = 73 ft (22.2 m) total

If the existing vent is round, a rectangular to round transition piece 
must be used. In addition, a rectangular 3" (7.6 cm) extension vent 
between the damper assembly and rectangular to round transition 
piece must be installed to keep the damper from sticking.
