THERMOSTAT CONTROL

OPERATION

The thermostatic control used on this fire-
place differs from standard thermostats.
Standard thermostats simply turn on and
off the burner. The thermostat used on
this fireplace senses the room tempera-
ture. 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 mea-

sures the temperature of air near the
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 fire-
place will let you determine your own
comfort levels.

MANUAL LIGHTING

PROCEDURE

OPERATING BLOWER

Auto/Off/On Switch

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 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.

Note:

 It is safe to operate fireplace with

blower turned off. However, the blower
helps distribute heated air from the
fireplace.
