OPERATING FIREPLACE

Continued

TO TURN OFF GAS

TO APPLIANCE

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 increase 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.

INSPECTING BURNERS

Check pilot flame pattern and burner flame pat- terns often.

PILOT FLAME PATTERN

Figure 51 shows a correct pilot flame pattern. Figure 52 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 52

•turn heater off (see To Turn Off Gas to Appli- ance, page 27 or 28 depending on situation)

•see Troubleshooting, page 30

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.

MAIN BURNER

Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage, blocked burner flame holes may create soot.
