3/8" drain hose can be connected to the built-in drain port of
the rubber boot on the blower assembly. For your convenience,
the rubber boot is supplied with a removable cap on the built-in
drain port. Prior to operating the water heater, make sure the
removable cap is installed on the drain port (if a drain hose is
not needed).
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 following 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 (13 mm) larger
than the marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch (6.4 mm) 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 (6.4 mm) 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 5
Cut a length of 3" PVC pipe about 3.5 inches (8.9 cm) longer
than the wall thickness at the opening. Glue the vent terminal
"45° Elbow" with screen to this section of pipe. Slide the wall
plate over the pipe to stop against "45° Elbow". 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 5).

PREPARATION OF BLOWER ASSEMBLY
1. Check to make sure that the wire harness is attached to the
gas valve and blower control box.
2. Make sure no material is still attached to the outside or inside
of blower assembly.
FIGURE 6
3. Make sure that plastic tubing is still attached to the pressure
switch and fan housing. Also make sure that wiring connector
from motor to control box is securely attached.
4. Do not plug in power cord until vent system is completely
installed. The Power Vent operates on 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 unit only where
local codes permit. If local codes do not permit use of flexible
power supply cord:
A. Remove screws that hold cover plate on control box and
remove plate.
B. Cut flexible power cord on inside of control box, as close
to inside wall as possible.
C. If flexible cord and strain relief are removed, then opening
in box must be covered by a plastic cap on the front side
of the control box.
D. Remove plastic cap on the right side of control box and
install suitable conduit fitting in enclosure.
E. Splice field wiring into existing wiring using code authorized
method (wire nuts, etc.).
F. Be certain that neutral and line connections are not reversed
when making these connections.
G. Ground heater properly. This water heater must be
grounded in accordance with the National Electrical Code
NFPA 70 or the Canadian Electrical Code CSA C22.1 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 7.
H. Replace cover plate and secure with two screws.
MUST INSTALL MINIMUM OF 2"
(5.1 cm) LONG PIECE OF 3" PIPE INTO
ELBOW TO MOUNT ON BLOWER
DISCHARGE ADAPTER. MAXIMUM
LENGTH FOUR (4) FEET (1.2 m).
