Always use a qualied technician or service agency to repair this replace.
!NOTE: Procedures and techniques that are considered important enough to emphasize.
CAUTION: Procedures and techniques which, if not carefully followed, will result in damage to the
equipment.
WARNING: Procedures and techniques which, if not carefully followed, will expose the user to the
risk of re, serious injury, or death.

OPERATION
Figure 1
To access the controls, ip open the control panel cover
towards the bottom of the replace. (Figure 1)
A. On/Off Switch
The On/Off Switch supplies power to all replace functions
(Heater/Flame).
B. Flame Action Control
Turn the Flame Action Control knob to adjust the ame
speed to the desired level.
C. Interior Light Control
Turn the Interior Light Control knob to increase or decrease
the brightness of the upper lights.
D. 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 thermostat 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.
E. LED Indicators
Indicates the current function of the replace: Level 1 -
Flame only; Level 2 - Flame and Low Heat; and Level 3 -
Flame with High Heat.
!NOTE: When the rebox is changing from Low heat
to High heat the speed of the fan does not change just the
amount of heat being emitted.
F. 3-Position Switch (Figure 3)
The 3-Position Switch operates the replace levels
sequentially, ame only to ame and low heat, to ame and
high heat. The level is increased every time the “ I“ side of
the switch is pressed. The replace can be turned off at any

point by pressing the “ II ” side of the switch.
Level 1: The ame effect is turned on and the rst red
indicator light ashes momentarily.
Level 2: The ame effect remains on, the heater is
activated to the low heat setting, and the rst and second
red indicator lights ash momentarily.
Level 3: The ame effect remains on, the heater is set
to the high heat setting, and all three red indicators ash
momentarily.
!NOTE: The heater may emit a slight, harmless odor
when rst used. This odor is a normal condition caused
by initial heating of internal heater parts and will not occur
again.
Figure 2
Resetting the Temperature Cutoff Switch
Should the heater overheat, an automatic cut out will turn
the replace 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 ve (5) minutes before switching the unit back
on.
If operating the unit with a remote control, the remote may
require re-initializing after turning the power off.
CAUTION: If you need to continuously reset the heater,
disconnect power and call Dimplex customer service at
1-888-DIMPLEX (1-888-346-7539).
Remote Control
The replace is supplied with a radio frequency remote
control. This remote control has a range of approximately
50 feet (15.25 m), it does not have to be pointed at the
replace and can pass through most obstacles (including
walls). It is supplied with one of hundreds of independent
frequencies to prevent interference with other units.
!NOTE: Before attempting any operation with the
remote control, pull the plastic insulator strip out from
between the remote casing and battery cover (Figure 2).
Remote Control Initialization/Reprogramming
This procedure may be required every time there is a loss
of power to the remote control in the replace. (i.e. power
failure, breaker tripped, On/Off switch is turned off)

at least 10 minutes for light bulbs and heating element
to cool off to avoid accidental burning of skin.
WARNING: Disconnect power before attempting any

Light bulbs need to be replaced when you notice a dark
section of the ame or when the clarity and detail of the log
exterior disappears. There are two bulbs at the top of the
opening that illuminate the log set exterior and three bulbs
under the log set which generate the ames and embers.
!NOTE: 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.
