The PVSA1 Air Pipe Kit is required for installation of the wall fur-
nace in a direct-vent configuration. See Page 15.
Max Vent Run - 50 ft. Equivalent
When installing a horizontal vent termination, the minimum vent
length protruding from the outside wall is 10 inches (304mm) for
exhaust and four inches for intake air.
See Figure 50.
For venting, cap exhaust with 45° elbow and intake air with 90º
elbow both pointed downward.
Notice:
All horizontal runs require a 1/4” per foot rise to run con-
densation back to the wall furnace.
Notice:
For each 45° elbow installed, reduce the length of the
run MUST be reduced by 1.5 feet (45 cm). Reduce the length
of the run three feet (91.4 cm) for every 90° elbow. The vent
terminal elbow does not contribute to the overall vent length
measurement.
