OPERATING FIREPLACE
Continued
Note: You may be running this fireplace for the first time after hooking up to gas sup- ply. If so, the control knob may need to be pressed in for 30 seconds or more. This will allow air to bleed from the gas system.

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 tem- perature 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 air near the fireplace cabinet. This may not always agree with room temperature (de- pending on housing construction, installation location, room size, open air temperatures, etc.). Frequent use of your fireplace will let you determine your own comfort levels.
