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 foryourprotection 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.
