CONNECTING PVC, ABS OR CPVC PIPE VENT TO
BLOWER
1. If making an immediate horizontal run of vent off the blower,
a 3" PVC, ABS or CPVC Schedule 40 (supplied locally) elbow
is required. Place the elbow in the required direction on the
blower and using 3 sheet metal screws, attach the elbow.
2. If there is to be a vertical run of vent from the blower, the 3”
PVC, ABS or CPVC pipe must be attached to the blower using
3 sheet metal screws.
The 3" (or optional 2") PVC, ABS, or CPVC Schedule 40 vent
pipe can be run from the water heater through the wall or from
the wall to the water heater, whichever is most convenient. The
vent pipe must extend a minimum of 114" through the exterior
wall. Extending the vent cap as far as possible from the surface
of the exterior wall will help minimize discoloration of the wall
in this area which may be caused by the flue gases. Note that the
inside collar must be slipped over the vent piping before locat­
ing the pipe through the wall. Before securing the inside and
outside collars to the wall, use a silicone sealer between pipe and
opening to insure a water and air tight seal.
3. If the optional 2" vent piping is to used, the 2" street elbow, 3"
to 2" reducer and 3" (minimum) section of 3" PVC, ABS or
CPVC pipe must be supplied locally. The 3" (minimum) section
of 3" PVC, ABS or CPVC pipe must be attached to the blower
using 3 sheet metal screws.
