OPTIONAL BLOWER INSTALLATION INSTRUCTIONS (continued)
Wiring
The appliance, when installed, must be electrically grounded in ac-
cordance with local codes or, in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70, if an external electrical source
is utilized. This appliance is equipped with a three-prong [ground-
ing] plug for your protection 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.
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
assembly.
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.
