to complete wiring of junction box.
Attention: If installed, do not damage gas inlet supply line

Wiring
The appliance, when installed, must be electrically grounded in
accordance 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 [grounding] 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.
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 Wheels
The blower wheels will collect lint and could require periodic
cleaning. If the air output decreases or the noise level increases,
it indicates a dirty blower wheel. Remove fan and clean blower
wheels.
WARNING: Unplugging of blower accessory will not stop the
heater from cycling. To turn off gas to the heater (millivolt
model): push in gas control knob slightly and turn clockwise
to "OFF." Do not force.
