OPERATION
This section will explain the function of each convent control.
To access the controls, open the upper grill by pulling near the top, forward and down.
A. MAIN ON/OFF SWITCH
The on/off switch supplies power to all fireplace functions (heater & flame).
B. FLAME SPEED CONTROL (not available on some models)
Turn the flame speed control knob to adjust the flame speed to the desired level.
C. FLAME LIGHT DIMMER CONTROL
Turn the flame brightness control to increase or decrease the brightness of the flame
and embers.
D. HEATER ON/OFF SWITCH
The heater on/off switch supplies power to the heating unit when the main on/off
switch (A) is in the on position.
E. HEATER THERMOSTAT CONTROL
To adjust the temperature to your individual requirements, turn the thermostat
control clockwise all the way to turn in the heater. When the room reaches the
desired temperature, turn the thermostat knob counter clockwise until you hear a
click. Leave in this position to maintain the room temperature at its setting. For
additional heat, turn clockwise until you hear the click again and the heater will turn
on. To turn the heater off, rotate the knob fully counter clockwise.
RESETTING THE TEMPERATURE CUTOFF
This unit is equipped with a thermostat which controls the temperature of the room.
It does this by turning the heater on and off. The heater is protected with a safety
device to prevent overheating. Should the heater overheat, an automatic cut out will
turn the heater off and it will not come back on without being reset. It can be reset
by switching the ON/OFF SWITCH to OFF and waiting 5 minutes before switching
the unit back on.
CAUTION
If you need to continuously reset the heater, unplug the unit and call your local
dealer.

UPPER BULB REPLACEMENT
Light bulbs need to be replaced when you notice a dark section in the flame or when the
clarity and detail of the log exterior disappears. There are two bulbs at the top of the
opening that illuminates the log set exterior and four bulbs under the log set which

WARNING
Allow at least 10 minutes for light bulbs to cool off before touching bulbs to avoid
accidental burning of skin.
HELPFUL HINTS
It is a good idea to replace all light bulbs at one time if they are close to the end of their
rated life. Group replacement will reduce the number of times you need to open the unit
to replace light bulbs.
