THERMOSTAT
CONTROL OPERATION
The thermostatic control used on this fireplace
differs from standard thermostats. Standard
thermostats simply turn on and off the burner.
The thermostat used on this fireplace senses the
room temperature. The thermostat adjusts the
amount of gas flow to the burner. This increases
or decreases the burner flame height. 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 (depending 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, blower will operate
constantly. In the OFF position, blower will not
operate. In the AUTO position, blower will start
when 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
blower turns on. After heater modulates to
pilot position, blower will continue to run.
Blower will shut off after firebox temperature
decreases.
Note: It is safe to operate fireplace with blower
turned off. However, blower helps distribute
heated air from fireplace.
