OPERATING

HEATER

Continued

CGHRCTA Series Operation:

2b. Press the AUTO/ON/OFF button on the hand-held remote control (see Figure 36). 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.

INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 37 shows a correct pilot flame pattern. Figure 38 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touch- ing the thermocouple. This will cause the thermocouple to cool. When the thermo- couple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 38

turn heater off (see To Turn Off Gas to Appliance, page 16)

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.
