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. To turn off gas on direct ignition
model, turn gas line valve to "OFF."
