F.
Joint assembly
Working quickly, insert the pipe into the fitting
socket bottom and give the pipe or fitting a 1/4 turn
to evenly distribute the cement. Do not continue
to rotate the pipe after it has hit the bottom of
the fitting socket. A good joint will have sufficient
cement to make a bead all the way around the
outside of the fitting hub. The fitting will have a
tendency to slide back while the cement is still wet
so hold the joint together for about 15 seconds.
Figure 45.
G.
Cleanup and joint movement
Remove all excess cement from around the pipe
and fitting with a dry cotton rag. This must be done
while the cement is still soft.
The joint should not be disturbed immediately
after the cementing procedure, and sufficient time
should be allowed for proper curing of the joint.
Exact drying time is difficult to predict because
it depends on variables such as temperature,
humidity and cement integrity. For more specific
information, you should contact your solvent
cement manufacturer.

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 47 through Figure 49).
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 the vent system is
completely installed. The heater operates on 110-120
VAC. A grounded outlet must be within reach of the 6
foot 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 the cover on
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.
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 current
edition of
“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 12; the wiring diagram).
g. Install the cover on the junction box and secure
it 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.
