PARTS LIST
Wiring
The appliance, when installed, must be electrically grounded in accordance
with local codes or, in the absence of local codes, with the National Electri-
cal Code, ANSI/NFPA 70, if an external electrical source is utilized. This
appliance is equipped with a three-prong [grounding] plug for your protec
-
tion against shock hazard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or remove the grounding
prong from this plug. For an ungrounded receptacle, an adapter, which has
two prongs and a wire for grounding, can be purchased, plugged into the
ungrounded receptacle and its wire connected to the receptacle mounting
screw. With this wire completing the ground, the appliance cord plug can
be plugged into the adapter and be electrically grounded.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
Blower Motor
The blower motor does not have oiling holes. Do not attempt to oil the
blower motor.
Blower Wheel
The blower wheel will collect lint and could require periodic cleaning.
If the air output decreases or the noise level increases, it indicates a dirty
blower wheel.
To clean blower wheel:
1. Turn OFF gas supply to the heater.
2. Turn OFF electrical supply to the heater.
3. Remove lower louver from casing assembly (2 screws).
4. Remove reflector from casing assembly (2 screws).
5. Remove upper louver from casing assembly (2 screws).
6. Clean blower wheel with a vacuum cleaner.
7. As parts are being replaced in reverse order, check for gas leaks at
all gas connections before lower louver is replaced onto casing as
-
sembly.
WARNING:
Unplugging of blower accessory will not stop the heater from cycling.
To turn off gas to the unvented heater: Push in gas control knob
slightly and turn clockwise to "OFF." Do not force.
If any of the original wire as supplied with the appliance must be replaced,
it must be replaced with type 125°C wire or its equivalent.
