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.
Maximum Length of Vent System
Vent | Length |
|

A | B | C |
A. External blower motor
B. Straight vent
C. 90° elbows
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) |
