SEQUENCE OF INSTALLATION
This unit can vent through two (2) or three (3) inch PVC pipe and
fittings. The vent terminal supplied with the unit must be used for
both two or three inch pipe.
The vent pipe installation can be started from either the blower
discharge or the termination wall. Keep in mind the total vent system
(pipe and elbows) when installing the vent system. (SEE VENT
CHART ON PAGES 9-10.)
FIGURE 4
The vent terminal should be kept as close as possible to the outside
wall, but you need to allow at least 1.5 inches of pipe past the wall,
for the wall flange and vent terminal to mount on the pipe.
Before the vent terminal is installed, caulk (not supplied) around the
pipe on the exterior wall and install the wall flange (can be held to the
outside wall by placing some of the caulking on the back of the flange).
Consider all of the 90 degree and 45 degree elbows, plus the number
of feet of pipe that would be needed for the installation of total vent
system.
Review the charts on Page9, to make sure that the vent system is
within the allowed vent configuration.
1. The FPSH/FPCR/FPST Power Vent Models come with the
blower assembly installed.
2. After the unit is set in place, make sure the blower assembly
is still mounted securely. Also make sure there is no
damage to the blower.
3. Make sure there is no packing material in the discharge of
the blower or the intake of the dilution air restrictor. See
Fig. 5 for description of blower parts.
4. Make sure that the plastic tubing is still attached from the
air pressure switch to the port on the blower housing.
5. Make sure the ON/OFF switch is in the OFF position and
then connect the outer harness from the blower control box
to the connector on the right side of the gas valve.
The two clips should be installed on the side of the water
heater and the wire placed through the opening in the side
of the clip. The clips should be placed so as to hold the
harness as close as possible to the side of the unit and
away from any hot surfaces.
