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 3 - 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.
