Wiring
The appliance, when installed, must be electrically grounded in accordance
with local codes or, in the absence of local codes, with the National Elec-
trical Code, ANSI/NFPA 70 or Canadian Electrical Code, CSA C22.1, 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 re-
ceptacle. 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. A 7/8" (22mm) hole is provided in
the junction box for use with a conduit connector if local codes require
this type of protection.
CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
Oiling the Motor
Oiling holes are provided on each end of the motor for oiling. The blower
should have five drops of #20 motor oil every 6 months. Do not use
machine oil.

Cleaning the Blower Wheel
In some areas, such as near bedrooms and on floors with a hard surface,
the blower wheel will be filled with lint very quickly. A visual check of
the blower wheel should be made after 30 days use. The blower will run
faster with a dirty wheel, but move less air. Remove the entire blower and
clean each blade of the wheel with a tooth brush as often as necessary.
Warning:
Unplugging of blower accessory will not stop the heater from cycling.
To shut heater off: 1. Turn the temperature dial to lowest setting, then
turn thermostat to off. 2. Turn knob on gas control to off, depressing
slightly. Do not force.
