The Y' PVC 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 1½" 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 locating the pipe through the
wall. Before securin_ the inside and outside collars to the wall,
use a silicone sealer between pipe and opening to insure a water
and air tight seal.

2. If there is to be a vertical run of vent from the blower, the 3"
PVC, ABS or galvanized pipe must be attached to the blower
using 3 sheet metal screws. If using galvanized piping attach-
ment is the same. Additionally, you must seal all joints using a
suitable silicone sealer such as GE RTV-103 or equivalent.
