Continued

•In the AUTO mode, the thermostat in the hand-held remote unit con- trols the room temperature. To in- crease the room temperature, press the top arrow of the TEMP button. To lower the room temperature, press the bottom arrow of the TEMP button. At higher settings the heater will run longer.

IMPORTANT: This remote control has been specially engineered to take an air temperature sample ev- ery minute in the auto mode. It will not respond immediately to the temperature setting being turned up or down.

IMPORTANT: The hand-held re- mote control unit must be near the heater. Do not keep the hand-held remote control unit too close to the heater. The thermostat on the hand-held remote control unit will heat up too quickly and turn the heater off.

OPERATION

WARNING: This fireplace has a three-prong, grounded electri- cal plug. This plug helps protect you against electrical shock. Only connect plug to a properly grounded, three-prong recep- tacle. Do not cut or remove the grounding prong from this plug.

Locate the blower switch by opening lower louver on fireplace. Blower switch is lo- cated at lower left inside louver door.

The GA3700TA thermostat-controlled blower has a variable speed control with an ON/OFF switch. The blower will start when the thermostat senses a sufficient increase in firebox temperature. The GA3700 variable speed blower also has an ON/OFF switch built into the variable speed control.

Note for GA3700TA Only: If you are using GA3700TA blower, your fireplace and blower will not turn on and off at the same time. The fireplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the firebox temperature decreases.

Note: It is safe to operate fireplace with blowerturnedoff.However,theblowerhelps distribute heated air from the fireplace.

Follow installation instructions included with the blower accessory.
