ATTENTION: Install blower assembly before connecting gas
inlet supply line
NOTE: Junction box on right side of replace must be pre-
wired at time of replace installation for use with blower
assembly. It is recommended that an ON/OFF wall switch be
installed by a qualied electrician that will activate the power
supply to the replace.
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 blower
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. To turn off gas on direct ignition
model, turn gas line valve to “OFF.”
