THERMOSTAT CONTROL OPERATION

The thermostat used on this fireplace senses the room temperature. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature.

The control knob can be set to any heat level between HI and LO.

Note: The thermostat sensing bulb measures the temperature of air near the fireplace cabinet. This may not always agree with room temperature (depend- ing on housing construction, installation location, room size, open air tempera- tures, etc.). Frequent use of your fireplace will let you determine your own comfort levels.

2.With control knob pressed in, strike match. Hold match to pilot until pilot lights.

3.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 24 shows a correct pilot flame pattern. Figure 25 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.
