H = 8 feet (2.438 meters) Max.
H + H 1 + H 2 = 20 feet (6.096 meters) Max.
Example: If 20 feet total (H+H
run is needed, then 4 feet minimum of (V) vertical
vent will be required.
This table shows a 1(V) to 5(H) ratio. For every
1 foot of (V) vertical, you are allowed 5 feet of
horizontal run up to a maximum total (H+H
horizontal run of 20 feet.
