INSTRUCTIONS FOR

ELECTRICAL POWER OUTAGE

ELECTRICAL POWER OUTAGE WARNING: You must operate this heater with the fireplace screen in place. Make sure fireplace screen is in place before running heater.

NOTICE: During initial operation of new heater, burning logs will give off a paper-burning smell. Open damper or window to vent smell. This will only last a few hours.

Because this fireplace has an electronic ignition system, in the event there is a loss of power, it will be necessary to manually light the pilot with the piezo ignitor. After the pilot is lit, the main burner will light automatically.

1.Follow steps 1 through 3 under Normal Lighting Instructions, pages 24.

2.Set manual ignition bypass switch on control panel to ON position (manual ignition position). See Figure 54.

3.The pilot is attached to the rear of the front burner. You will be able to see the pilot and spark electrode without removing the screen or logs.

4.Place the magnetic manual override handle, provided with this unit, on the end of the gas valve stem (see Figure 54).

5.Turn the override handle fully counterclockwise OPTIONAL BLOWER to the PILOT position. The handle will not stop but will begin to slip when you have fully turned to the PILOT position.

6.While holding the valve handle in the PILOT position, press and release piezo ignitor button (see Figure 54). This will light the pilot. If needed, keep pressing ignitor button until pilot lights.

7.When pilot flame is lit, hold manual override handle until thermocouple heats (approximately 5 to 15 seconds). If pi- lot goes out, repeat process. If several attempts to light the pilot fail, contact a qualified service person or gas supplier for repairs.

8.When thermocouple is heated, release override handle. The main burner will immediately light on high flame. Adjust flame size by turning override handle.

Shutting Off Heater When Manually Lit

Set manual ignition bypass switch on control panel to OFF (automatic ignition position). This will cause the controls to shut down the fireplace.

OPTIONAL BLOWER

OPERATION

Locate the blower switch by opening lower louver on fireplace. Blower switch is located at lower right inside louver door.

The GA3650T/GA3700T Series thermostat-controlled blower has a variable speed control with an ON/OFF switch. The blower will start when the thermostat senses a sufficient in- crease in firebox temperature. The GA3700/GA3750 Series variable speed blower also has an ON/OFF switch built into the variable speed control.

Note for GA3650T/GA3700T Series Only: If you are using this series 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 blower turned off. However, the blower helps distribute heated air from the fireplace.

Follow installation instructions included with the blower accessory.
