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.
