THERMOSTAT CONTROL
OPERATION
The thermostat used on this fireplace senses the room tempera-
ture. 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 air near the
fireplace cabinet. This may not always agree with room tem-
perature (depending on housing construction, installation loca-
tion, 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 operate constantly. In the OFF posi-
tion, the blower will not operate. In the AUTO position, the
blower will start when the thermostat senses a sufficient in-
crease 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.
Note: It is safe to operate fireplace with blower turned off.
However, the blower helps distribute heated air from the fireplace.
