Fan Control
The automatic fan control is located on the bottom of the blower assembly.
The fan control is a nonadjustable, automatic type. The fan control will
require between 3 and 7 minutes of main burner operation before the fan
control "closes" and activates the blower. The blower will continue to run
between 3 and 7 minutes after the main burner shuts off, before the fan
control "opens" and deactivates the blower.
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 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
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 screws. With this wire
completing the ground, the appliance cord plug can be plugged into the
adapter and be electrically grounded.
WARNING:
Unplugging of blower accessory will not stop the heater from
cycling. To shut heater off: Turn temperature dial or thermostat
to lowest setting. Turn knob on gas control to "OFF", depressing
slightly. Do not force.
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 blower motor does not have oiling holes. Do not attempt to oil the
blower motor.
