of the rubber boot vent adapter is capped off. Lastly, make sure
there is no damage to the blower.
3. Condensate drains from two locations on the blower assembly as
shown in figure 17. A condensate hose must be secured to form a
"trap" as shown in figure 17 for these condensate drain connections.
These two hoses may be connected together. The hose(s) should
be routed to a suitable drain. A fitting that may be used to join the
two hoses from the blower assembly is included in a supplied kit.

4. Make sure there is no packing material in the inlet or discharge
of the blower.
5. Make sure that the plastic tubing is still attached from the air
pressure switch to the port on the blower housing. Make sure
the plastic tubing is not folded anywhere between the pressure
switch and the blower housing.
6. Make sure the ON/OFF switch is in the OFF position and that
the outer harness is connected from the blower control box to
the connector on the bottom side of the gas valve.
7. If the outer harness is not factory installed, 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
bottom side of the gas valve.
8. Do not plug in power cord until vent system is completely installed.
The Power Vent operates on 110 -120 Vac. therefore a grounded
outlet must be within reach of the 6 foot (1.8 m) flexible power
cord supplied with the vent (See Figure 1). The power cord
supplied may be used on a unit only where local codes permit.
If local codes do not permit use of flexible power supply cord:
A. Make sure the unit is unplugged from the wall outlet. Remove
the plastic top cap. Remove screws and open panel on the
front of the control box on the blower.
B. Cut the flexible power cord, leaving enough to be able to make
connections. Remove the strain relief fitting from the box.
C. Install a suitable conduit fitting inside the enclosure.
D. Splice field wiring into existing wiring using code authorized
method (wire nuts, etc).
E. Be certain that neutral and line connections are not reversed
when making these connections.
F. Ground heater properly. This water heater must be grounded in
accordance with the National Electrical Code NFPA 70 and/or
local codes. These must be followed in all cases.
The water heater must be connected to a grounded metal,
permanent wiring system; or an equipment grounding
conductor must be run with the circuit conductors and
connected to the equipment grounding terminal or lead on
the water heater, see Figure 19.
G. Close the panel on the control box. Make sure that the access
panel is secured shut.
9. The blower discharge boot is made to accept only straight sections
of 2" pipe. To start off with an elbow, a short section of the furnished
pipe, a minimum of 2 inches, must be cut and glued into the end of
the elbow that will mount on the discharge boot.
INSTALLATION OF VENT SYSTEM
Before beginning installation of piping system thoroughly read the
section of this manual VENT PIPE PREPARATION.
If you are installing your system so that it vents through roof, please
refer to section titled INSTALLATION OF VERTICAL VENT SYSTEM.
VENT TERMINAL INSTALLATION, SIDEWALL
1. Install the vent terminal by using the cover plate as a template to
mark the hole for the vent pipe to pass through the wall. BEWARE
OF CONCEALED WIRING AND PIPING INSIDE THE WALL.
2. If the Vent Terminal is being installed on the outside of a finished wall, it
may be easier to mark both the inside and outside wall. Align the holes
by drilling a hole through the center of the template from the inside
through to the outside. The template can now be positioned on the
outside wall using the drilled hole as a centering point for the template.
3. A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch larger than the
marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch outside of the marked
circle. This pilot hole is used as a starting point for a saws-all or sabre
saw blade. Cut around the marked circle staying approximately one
quarter inch outside of the line. (This will allow the vent to easily slide
through the opening. The resulting gap will be covered up by the
Vent Terminal cover plate.) Repeat this step on inside wall if necessary.
SEQUENCE OF INSTALLATIONS, FIGURE 18
Cut a length of PVC pipe about 3.5 inches longer than the wall thickness at
the opening. Glue the vent terminal to this section of pipe. Slide the wall
plate over the pipe to stop against the vent terminal. Place a bead of caulking
(not supplied) around the gap between the pipe and cover plate. Apply
enough to fill some of the gap between the pipe and wall. Place some of
the caulking on the back of the plate to hold it against the wall after installation.
If the vent pipe is installed up to the wall, with a coupling on the end against
the wall opening, the pipe with the vent terminal can be prepared for gluing
before inserting through the wall. Slide the pipe through the wall and insert
into the coupling on the other side of the wall, making sure that the vent
terminal ends up pointed in the correct position, see Figure 18.
