OPERATION
To access the controls, go to the back of the stove.
A. MAIN POWER ON/OFF SWITCH
The main on/off switch supplies power to all unit
functions (flame, purifire, heater).
B. MANUAL SELECTION SWITCH
To choose between flame effect setting, flame
effect with Purifire™ setting, and flame effect with
Purifire™ and heat setting.
C. INTERIOR LIGHT ON/OFF SWITCH
The interior light on/off 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 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 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.

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 transmitter.

fireplace can be turned off at any point by pressing
the OFF button on the remote control transmitter.
