for ve (5) seconds. After ve (5) seconds, there is a
10 second window to press any button on the remote
control.
Press any button on the remote control within that 105.
seconds.
This will synchronize the remote control and receiver.
Remote Control Usage
The remote control operates the replace levels
sequentially (beginning with): ames only; to ames and
low heat; to ames and high heat. The level is increased
every time the ON button is pressed on the remote control
and the replace can be turned off at any point by pressing
the OFF button.
Battery Replacement
To replace the battery:
Slide battery cover open on the remote control (Figure 1.
2).
Install one (1) 12-Volt (A23) battery in the battery2.
holder.
Close the battery cover.3.
Battery must be recycled or disposed of properly.
Check with your Local Authority or Retailer for
recycling advice in your area.
OPERATION
Figure 1
The manual controls for the electric replace are located on
the right end of the unit.
A. On/Off Switch
The On/Off Switch supplies power to all replace
functions. When the switch is in the “ I” position, the
unit is on. When in the “ O ” position, the replace is
off.
B. 3-Position Switch
The 3-Position Switch changes the mode the replace
operates in and has three (3) positions: “ MANUAL ”; “
OFF ”; and “ REMOTE ”.
When in “ REMOTE ” mode, the replace’s three levels
of operation are controlled by the ON and OFF buttons
of the remote control.
In “ OFF ” mode, power to all functions is cut off.
In “ MANUAL ” mode, the replace’s three levels of
operation are controlled by the Manual Control Buttons.
C. Manual Control Buttons
The Manual Control Buttons operate the replace levels
sequentially (beginning with): ames only; to ames
and low heat; to ames and high heat.
The level is increased every time the “ I” button is
pressed. The replace can be turned off at any point by
pressing the “ O” button.
Resetting The Temperature Cutoff Switch
Should the heater overheat, an automatic switch will turn
the heater off and it will not come back on without being
reset. The temperature cutoff switch can be reset by
unplugging the unit, waiting ve (5) minutes and plugging
the unit back in.
CAUTION: If you need to continuously reset the heater,
unplug the unit 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

MAINTENANCE
WARNING: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of re, electric
shock or damage to persons.
Mirror Cleaning
The Partially Reective Glass is cleaned in the factory dur-
ing the assembly operation. During shipment, installation,
handling, etc., the Partially Reective Glass may collect
dust particles. These can be removed by dusting lightly
with a clean dry cloth.
To remove ngerprints or other marks, the Partially Reec-
tive Glass can be cleaned with a damp cloth. The Partially
Reective Glass should be completely dried with a lint free
cloth to prevent water spots. To prevent scratching, do not
use abrasive cleaners.
Fireplace Surface Cleaning
Use only a damp cloth to clean painted surfaces of the
replace. Do not use abrasive cleaners.
Servicing
Except for installation and cleaning as described in this
manual, an authorized service representative should per-
form any other servicing.

!NOTE: Be sure that the anges on the bottom panel
are positioned on the interior of the side and back panels of
the replace.
The air deector panel located on the interior of the bottom
panel will need to be carefully t over the heater assembly
elements. This may take some careful maneuvering, slid-

second side.
The t is tight and a at instrument such as a at head
screwdriver may be helpful to guide the second side when
pushing the bottom panel in place. Use care to not scratch
the visible surface of the bottom.

WARNING: If the replace was operating prior to ser-
vicing, allow at least 10 minutes for light bulbs and heating
elements to cool off to avoid accidental burning of skin.
WARNING: Disconnect power before attempting any
maintenance to reduce the risk of electric shock or damage
to persons.
Remove the replace from the wall by carefully lifting it 1.
upward, releasing it from the anges of the wall-mount-
ing bracket. (Figure 3).
Carefully lay the replace down on its front.2.
!NOTE: If necessary, lay a protective barrier between
the front glass and your work surface, (i.e. cloth, cardboard,
thick plastic) to avoid scratching the glass or your work
surface.
Remove the left and right side exterior cover panels3.
from the body of the rebox by removing the screw on

Remote Control Receiver is the large board located
closest to the switches on the right.
Transfer the wire connectors from the terminals on the9.
original board to the same location on the replacement

back panel. They can be cut either from: above – ush
to the board; or below the board - ush to the back
panel. Once the mounting tabs are cut, pull the board
off of the tabs, and remove the board from its location,
noting its original orientation.
Raise the bottom of the replace off your work surface 11.
and using needle nose pliers push the remainder of the
original mounting tabs out of the back panel and push
the new mounting tabs (supplied with the new board),
