NOTE:
•Horizontal sections require a 1/4" rise every 12" of travel.
•The maximum vertical height is 40'.
•The maximum horizontal length is 25'.
•One horizontal elbow is allowed. The horizontal vent length is calculated by adding the length before and after the elbow (H1 + H2 = horizontal vent length).
H2 H2
This is considered a horizontal elbow (it does not matter whether it turns right or left).
It may be a 45° or 90° elbow.
H1
This is considered a vertical elbow
Horizontal length is calculated by adding both lengths of horizontal run (Horizontal Length = H1 + H2).
This is considered a vertical elbow
