How to Read
the Venting
Chart
The total length of the vent pipe cannot exceed 40’ (12.2m).
The minimum vertical height with roof termination is 8’ (2.45 m).
Any combination of rise and run can be used as long as they are within the allowable
limits shown on the chart below.
A maximum of 5 x 90° elbows—or equivalent (2 x 45° = 90°)—can be used.
Each 90° elbow installed on the horizontal plane is equivalent to a 3’ horizontal pipe;
therefore, 3’ must be subtracted from allowable horizontal run. (45° elbow is equivalent
to 18” horizontal pipe.)
All horizontal pipe runs must be graded 1/4” per foot upwards in the direction of the
exhaust flow.
Co-linear rear venting in existing chimney systems is limited to 40’ vertical rise.
Restrictors are not required for co-linear installations.
