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.

OPERATING

BLOWER

This blower has three settings: ON, OFF, and AUTO. In the ON position, the blower will oper- ate 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 fireplace and thermostat blower will not turn on and off at the same time. The fireplace may run for several minutes before the blower turns on. After the heater modulates to the pilot position, the blower will continue to run. The blower will shut off after the firebox temperature decreases.
