Fan Control
The automatic fan control is located in the switch box. The
switch box is attached to the front of the blower assembly.
The switch box is adjacent to the combustion chamber. 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 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.
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.
