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.
MANUAL LIGHTING
PROCEDURE
1. Follow steps 1 through 5 under Lighting Instructions, page 23.
2. With control knob pressed in, strike match. Hold match to
pilot until pilot lights.
3. Keep control knob pressed in for 30 seconds after lighting
pilot. After 30 seconds, release control knob. Now follow
step 8 under Lighting Instructions, page 23.
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.

FOR YOUR SAFETY
READ BEFORE LIGHTING
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing prop-
erty damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone in
your building.
• Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire de-
partment.
C. Use only your hand to push in or turn the gas control knob.
Never use tools. If the knob will not push in or turn by
hand, don't try to repair it, call a qualified service techni-
cian or gas supplier. Force or attempted repair may result
in a fire or explosion.
D. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect
the appliance and to replace any part of the control system
and any gas control which has been under water.
