Venting
How to Read the Venting Chart
The chart below applies to roof or wall termination
.
1. The total length of the vent pipe cannot exceed 40
feet (12.2 m).
2. The minimum vertical height with roof termination is
6 feet (1.83 m).
3. Any combination of rise and run can be used as
long as they are within the allowable limits shown
on the chart below.
4. A maximum of 4 x 90 degrees elbows—or
equivalent (2 x 45 degr. = 90 degr.)—can be used.
5. Each 90 degrees elbow installed on the horizontal
plane is equivalent to a 3 feet horizontal pipe;
therefore, 3 feet must be subtracted from allowable
horizontal run. (45 degrees elbow is equivalent to
18 inches horizontal pipe.)
6. All horizontal pipe runs must be graded 1/4 inch per
foot upwards in the direction of the exhaust fl ow.
The fi nal pipe length, when terminating through the
wall may be graded downwards slightly to prevent
water migration.
7. Co-linear venting is not allowed .
8. A restrictor is required for many installations—see
next section.
