Roof Termination Venting Charts
24” Pipe
Length Min.
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 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.
** All dimensions are approximate. Both rise and run may vary with different combinations of pipe.
