THERMOSTAT CONTROL OPERATION
The thermostat used on this fireplace senses the room temperature. At times the

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.
The thermostat sensing bulb measures the temperature of air near the
Note:
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.
