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.
