OPERATING FIREPLACE INSERT

Continued

GHRCTA Series Operation:

2b. Press theAUTO/ON/OFF button on the hand-held remote control (see Figure 35, page 15). The lights to the left of the button will show AUTO, ON, or OFF.

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

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 5.5 minutes 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.

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 control knob on the heater to the OFF position.

OPTIONAL BLOWER

OPERATION

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

Thisthermostat-controlledblowerhasthree settings: ON, OFF, and AUTO. In the ON position, the blower will operate constantly. In the OFF position, the blower will not operate. In the AUTO position, the blower will start when the thermostat senses a sufficient increase in firebox temperature.

Note: Your gas logs and thermostat blower will not turn on and off at the same time. The fireplace insert may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will con- tinue to run. The blower will shut off after the firebox temperature decreases.

Note: It is safe to operate fireplace insert with blower turned off. However, the blower helps distribute heated air from the fireplace insert.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 36 shows a correct pilot flame pat- tern. Figure 37 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 37

turn heater off (see To Turn Off Gas to Appliance, page 15)

see Troubleshooting, pages 17 through 19

BURNER PRIMARY AIR HOLES

Air is drawn into the burner through the holes in the fitting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot.

MAIN BURNER

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

BURNER FLAME PATTERN

Figure 38 shows a correct burner flame pat- tern. Figure 39 shows an incorrect burner flame pattern. If burner flame pattern is incorrect,

turn heater off (see To Turn Off Gas to Appliance, page 15)
