Blower Exhaust
Direction
The blower assembly may be rotated 90 degree
clockwise or counterclockwise
to allow horizontal
venting in areas having restricted space above the
water heater. To rotate the blower outlet, remove
the four nuts (with 11132" nut driver) (see Figure
37), securing the flue collector to the blower
housing. Pull the blower assembly forward to free it
from the mounting studs. Rotate the blower housing
clockwise or counter-clockwise
and align the four
holes and screws together. Reattach the blower
housing to the flue collector.
Note: coupling to vent system not
shown for clarity.

1. This power vented water heater comes with
blower assembly installed (see Figure 21).
2. After water heater 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 housing. Make sure the plastic tubing
is not folded anywhere between the pressure
switch and the blower housing (see Figures 33-
36).
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 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 heater. 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 screw and open panel
on the front of the junction 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 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
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 44).
g.
Close the panel on the junction box. Make
sure that the access panel is secured shut.
7. The blower discharge boot is 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 on the discharge boot.
