OPERATING FIREPLACE

Continued

GHRC Series Operation:

2a. Press the ON/OFF button to turn the burner on and off. When turning burner off, the pilot will remain lit.

GHRCTA Series Operation:

2b. Press the AUTO/ON/OFF button on the hand-held remote control (see Figure 42). The lights to the left of the button will show AUTO, ON, or OFF.

In the ON mode, the burner will ignite. The heater is in manual mode when ON is lit.

In the AUTO mode, the thermostat in the hand-held re- mote unit controls the room temperature. To increase the room temperature, press the top arrow of the TEMP but- ton. 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 en- gineered to take an air temperature sample every minute in the auto mode. It will not respond immediately to the temperature setting being turned up or down.

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

3.To turn the burner off, press the AUTO/ON/OFF button until OFF lights. The pilot will remain lit.

IMPORTANT: To turn the pilot off, manually turn the con- trol knob on the fireplace to the OFF position.

OPTIONAL BLOWER

OPERATION

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

The GA3700T Series thermostat-controlled blower has a vari- able 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 GA3700T Series Only: If you are using GA3700T 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 patterns often.

PILOT FLAME PATTERN

Figure 43 shows a correct pilot flame pattern. Figure 44 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 44
