NOTE: The vent must not exceed a total length of 68 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 combina-
tion of other elbows equalling 90° can be used without reducing
horizontal run. For each additional 90° elbow, or an equal com-
bination of elbows, reduce horizontal vent run by 2 feet. Ensure
vent pipe is properly supported.
