Calculate Vent System Length
The recommended vent system length is 3¹⁄₄" x 10" (8.3 cm x
25 cm) vent with maximum length of 26 ft (8 m) for vent system.
For the best performance, use no more than three 90° elbows.
To calculate the length of the system, add the equivalent feet
(meters) for each of the vent pieces used in the system.

3 ft
(0.93 m)
Maximum Length = 26 ft (8 m)
1 - 90° elbow = 5 ft (1.5 m)
1 - wall cap = 0 ft (0 m)
9 ft (2.8 m) straight = 9 ft (2.8 m)
System length = 14 ft (4.3 m)
