Fan Control
The fan control is a non-adjustable automatic type. The fan control
will require between 5 and 10 minutes of main burner operation
before the fan control "closes" and activates the blower. The blower
will continue to run between 5 and 10 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 No. 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 screws.
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.
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.
