OPERATION
To access the controls, go to the back of the stove.
A. ON/OFF SWITCH
The On/Off switch supplies power to all unit
functions (flame, purifire, heater).
B. 3-POSITION SWITCH
To choose between flame effect setting, flame
effect with Purifire™ setting, and flame effect with
Purifire™ and heat setting.
C. INTERIOR LIGHT SWITCH
The interior light switch supplies power to
the interior light.
D. 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 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 this setting. For additional
heat, turn clockwise until you hear the click again
and the heater will turn on.

RESETTING THE TEMPERATURE CUTOFF SWITCH
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 Dimplex technical support
at 1-888-DIMPLEX (1-888-346-7539) Extension 4.
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.

REMOTE CONTROL USAGE
This stove 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). It is supplied with one of 243 independent
frequencies to prevent interference with other units. The frequency code is indicated on the
back of the remote control.
A. 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, On/Off switch is
turned off)
Frequency
Code
1. Ensure that power is supplied through main
service panel.
2. Locate manual controls. (refer to FIGURE 3)

3-POSITION SWITCH
The 3-position switch operates the electric fireplace in the same manner as the remote control.
Pressing the switch up (“ I ” position) has the same effect as the ON button on the remote
control and pressing the switch down (“ II ” position) has the same effect as the OFF button of
the remote control. Pressing the switch up once activates Level 1, twice activates Level 2, and
three times activates Level 3. Pressing the switch down turns the electric fireplace OFF.
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.

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. There are
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.
UPPER LIGHT BULB REPLACEMENT
