Wall venting
For wall or roof venting methods:
If the wall exhaust method is chosen, be sure that
there is proper clearance within the wall for the
exhaust vent.
Wall and roof caps must have back-draft damper.
We recommend:
using rigid metal vent.

Use 3-1/4" x 10" or 6" vent. The total length of the vent system
including straight vent, elbow, transitions, wall or roof caps
must not exceed the equivalent of 140 feet of
3-1/4" x 10" rectangular or 6" diameter round vent. For best
performance, use no more than three 90° elbows. To calculate
the length of system you need, add the equivalent feet for
each vent piece used in the system. See examples below.
