CUTTING OPENING THROUGH AN OUTSIDE
WALL AND COLLAR INSTALLATION
After reading the manual and you have determined the location
of the opening in the wall, (using the drawing below), cut a y/z"
hole through an exterior wall,
NOTE: When determining location of the opening in the
outside allow for the
'/*' rise per foot that has taken
place in the horizontal run.
CONNECTING PVC, ABS OR CPVC PIPE VENT TO
BLOWER
1. The manufttaurer has supplied a 3" PVC or ABS Schedule 40
street elbow for connection to the water heater when turning
immediately horizontally off the blower. Place the elbow in
the required direction on the blower and using 3 sheet metal
screws, attach the elbow. If using a galvanized elbow attach­
ment is the same.
The 3" PVC Schedule 40 vent pipe can be run ftom 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, ^tending the vent
cap as (ar 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 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.
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.
