OPERATION
Three switches provide a choice of heat settings (FIG. 1). A switch is in the ON position
when the side with the markings on (i.e. I, I, or II) is pushed in.
Switch 1 (I) Controls the electricity supply to the heater and flame effect.
Note: This switch must be in the ON (I) position for heater to operate with or without
heat.
Switch 2 (I) Provides 600 W heat output.
Switch 3 (II) Provides 1200 W heat output with switch 2.
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 North
America Limited at 1-800-668-6663.

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
two bulbs under the log set which generate the flames and embers located under the
emberbed.
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.
