of Pipe
NOTE: The vent must not exceed a total length of 65 feet.
Any combination of rise and run may be used but must be
constrained to the boundaries of this chart. A total of 4 90°
elbows or combination of other elbows equalling 90° can be
used without reducing horizontal run. For each additional 90°
elbow, or an equal combination of elbows, reduce horizontal
vent run by 2 feet. Ensure vent pipe is properly supported.
