Vent Pipe Runs

1. The exhaust vent system must not, under any
circumstances, be run downhill then run uphill thus
forming a valley. It may leave a space to accumulate
condensation and block vent pipe.
2. Horizontal runs require a minimum 3mm (1/8") rise per
1.52m (5') and a support every 1.2m (4') or according
to venting manufacturer's instructions. Ensure there
is enough height between heater and termination to
raise vent pipe runs the required distance.
3. Vertical runs require a support every 1.52m (5') that
must provide proper support to prevent stress on
the pipes or according to venting manufacturer's
instructions.

Vent Terminal Installations

Important: The vent system must terminate so that proper
clearances are maintained as cited in local codes or the
latest edition of "Natural Gas and Propane Installation
Code" B149.1 .
In addition, the manufacturer recommends the vent
terminal not to be installed closer than 152mm (6") from
an inside or outside corner.
Plan the vent system layout so that proper clearances
are maintained from plumbing and wiring. Vent pipes
serving power vented appliances are classifi ed by building
codes as "vent connectors". Required clearances from
combustible materials must be provided in accordance
with information in this manual under ""Locating The New
Water Heater" and with the latest edition of "Natural Gas
and Propane Installation Code" B149.1 and local codes.

BLOWER ASSEMBLY INSTALLATION

1. This power vented water heater comes with blower
assembly installed.
2. After unit is set in place, make sure blower assembly is
still mounted securely. Make sure there is no damage
to blower.
3. Make sure there is no packing material in the inlet or
discharge of the blower.
4. Make sure that the plastic tubing is still attached from
the air pressure switch to the port on the blower motor
housing. Make sure the plastic tubing is not folded
anywhere between the pressure switch and the blower
motor housing (see Figure 30 thru Figure 34).
5. This water heater is a polarity sensitive appliance and
will not operate if the power supply polarity is reversed.
Power to this water heater must be wired properly
(correct polarity).
6. Do not plug in power cord until vent system is
completely installed. The Power Direct Vent operates
on 110 -120 VAC. therefore a grounded outlet must be
within reach of the 6 foot fl exible power cord supplied
with the heater. The power cord supplied may be used
on a unit only where local codes permit. If local codes
do not permit use of fl exible power supply cord:
a. Make sure the unit is unplugged from the wall
outlet. Remove the screw and open panel on the
front of the junction box on the blower.
b. Cut the fl exible power cord, leaving enough to be
able to make connections. Remove the strain relief
fi tting from the box.
c. Install a suitable conduit fi tting inside the enclosure.
d. Splice fi eld wiring into existing wiring using code
authorized method (wire nuts, etc).
e. Be certain that the 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 current edition of
"Canadian Electrical Code (CAN/CSA C22.1),
Part I" 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 11; the wiring diagram).
g. Close the panel on the junction box. Make sure
that the access panel is secured shut.
7. The blower discharge has a rubber coupling made to
accept only straight sections of 2" or 3" pipe. To start
off with an elbow, a short section of the straight pipe
must be cut and glued into the end of the elbow that
will mount in the rubber coupling.
