OPERATION
This section will explain the function of each convenient control.
To access the controls, open the upper grill by pulling, near the top right hand side,
forward and down.
A. MAIN ON/OFF SWITCH
The ON/OFF SWITCH supplies power to all fireplace functions (Heater/Flame).
B. FLAME ACTION CONTROL
Turn the flame action control knob to adjust the flame speed to the desired level.
C. FLAME BRIGHTNESS CONTROL
Turn the flame brightness control knob to increase or decrease the brightness of the
flame and embers.
D. LED INDICATORS
Indicates the current function of the fireplace.
E. MANUAL SELECTION SWITCH
To choose between flame effect setting, flame effect with low heat setting, and flame
effect with high heat setting.
F. HEATER THERMOSTAT CONTROL
To adjust the temperature to your individual requirements, turn the thermostat control
clockwise all the way to turn on the heater. When the room reached the desired
temperature, turn the thermostat knob counter clockwise until you hear a click. Leave in
this position to maintain the room temperature at this setting. For additional heat, turn
clockwise until you hear the click again and the heater will turn on.
NOTE:
The heater may emit a slight, harmless odor when first used. This odor is a normal
condition caused by initial heating of internal heater parts and will not occur again.
RESETTING THE TEMPERATURE CUTOFF SWITCH
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 main 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.

REMOTE CONTROL USAGE
The fireplace is supplied with a radio frequency remote control. This remote control has
a range of approximately 50 feet. (15.25m), it does not have to be pointed at the
fireplace and can pass through most obstacles (including walls).
Remote Control Initialization
This procedure is required every time there is a loss of
power to the remote control in the fireplace. (i.e. power
failure, breaker tripped, main power switch is turned off)
1. Ensure that power is supplied through main
service panel.
2. Locate manual controls (refer to OPERATION
section).
3. Activate main power switch, red indicator lights will
flash momentarily.
4. Press ON button located on the remote control
transmitter (FIGURE 1). This will synchronize the
remote control transmitter and receiver.
Remote Control Usage
The remote control operates the fireplace levels
sequentially. The level is increased every time the ON
button on the transmitter is pressed. The fireplace can
be turned off at any point by pressing the OFF button
on the remote control transmitter.
Level 1: The flame effect is turned on and the first red
indicator light flashes momentarily.
Level 2: The flame effect remains on, the heater is
activated to the low heat setting, and the first and
second red indicator lights flash momentarily.
Level 3: The flame effect remains on, the heater is set
to the high heat setting, and all three red indicators
flash momentarily.
MANUAL SELECTION SWITCH

control transmitter. Pressing the right side of this switch
has the same effect as the button on the
remote control and the right side has the same effect as
the button of the remote control. Pressing once to
the left activates Level 1, twice activates Level 2, three
times activates Level 3. Pressing to the left side turns
the fireplace off.

If unit was operating prior to servicing allow at least 10 minutes for light bulbs and
heating element to cool off to avoid accidental burning of skin.
Disconnect power before attempting any maintenance or cleaning to reduce the risk of
electric shock or damage to persons.
Light bulbs need to be replaced when you notice a dark section of 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
generate the flames and embers.
It is a good idea to replace all of the 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 the light bulbs.
TO REPLACE UPPER LIGHT BULBS
1. Remove the firebox trim by placing your hand on the grill section, grasping the
trim and pulling outwards releasing the retainer clips.
2. Remove the mounting screw in the center of the glass and remove the retainer
bracket.
3. Remove the glass by lifting up from the bottom.
CAUTION
Even though the glass is safety glass it may break if bumped, struck of dropped.
Care must be taken when handling the glass.
4. Locate upper bulbs inside the center of the firebox at the top.
5. Replace bulb(s) that require replacement, holding onto the light socket when
while unscrewing.
6. Reassemble in the reverse order as above.
UPPER BULB-Quantity 2 chandelier or candelabra bulbs with an E-12 (small)
