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

The GA3650T 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.

IMPORTANT: Light your gas appliance with the blower off.

Note for GA3650T: If you are using GA3650T blower, your gas 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.

Note: Periodically check the louvers of the firebox and remove any dust, dirt, or other obstructions.

Follow installation instructions included with the blower accessory.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 32 shows a correct pilot flame pat- tern. Figure 33 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the fireplace will shut down.

If pilot flame pattern is incorrect, as shown in Figure 33

•turn fireplace off (seeTo Turn Off Gas to Appliance, page 15 [Thermostat-con- trolled models] or page 16 [Manually- controlled models])

•seeTroubleshooting, pages 19 through 21

FRONT BURNER FLAME PATTERN

Figure 34 shows correct front burner flame pattern. Figure 35 shows incorrect front burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of blue flame.

WARNING: If front burner flame pattern shows yellow tip- ping, your fireplace could pro- duce increased levels of carbon monoxide. Follow instructions at bottom of this page. Yellow flame on rear burner is normal.

NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles are burned by fireplace, causing brief patches of orange flame.

If front burner flame pattern is incorrect, as shown in Figure 35

•turn fireplace off (seeTo Turn Off Gas to Appliance, page 15 [Thermostat-con- trolled models] or page 16 [Manually- controlled models])
