Remote Operation
The replace is supplied with an integrated On/Off remote
control.
!NOTE: Ensure that the replace 3 position switch is set
to the remote control setting, “II”. To operate, push the ON
button to turn replace on, push the OFF button to turn the
replace off.
!NOTE: Before attempting any operation with the remote
control, pull the plastic insulator strip out from between the
remote casing and battery cover (Figure 5).
Remote Control Initialization/Reprogram
In the event that your remote control ceases to operate
your replace, follow these steps to reinitialize the remote
control and the remote control receiver in the replace:
1. Place the 3-Position Switch (Figure 1A) in the OFF
(“O”) position.
2. Wait a minimum of 5 seconds and then place the 3-Po-
sition Switch in the Remote Control position.
3. Within 10 seconds of changing the switch position,
press the ON button located on the remote control
(Figure 2). This will synchronize the remote control and
the replace receiver.
!NOTE: You will have only 10 seconds to perform this
last step. Failure to do so will result in these steps needing
to be followed again.
Battery Replacement
To replace the battery:
1. Slide battery cover open on the remote control (Figure
2).
2. Correctly install one 12 Volt (A23) battery in the battery
holder.
3. Close the battery cover.
Battery must be recycled or disposed of properly.
Check with your Local Authority or Retailer for recyc-
ling advice in your area
OPERATION
The controls are located on the upper right of the replace.
(Figure 1)
A. 3-Position Switch
The switch has two ON positions marked with “ I“ and “ II “
. The “ I“ position is for manual operation. In this position
the built-in remote control is by-passed.
The “ II “ position is for operating the unit with the provided
remote control.
When in the “ II “ position the unit is operated with the ON
and OFF buttons of the remote control. When the switch is
in the center position the unit is off.
B. Heater ON/OFF Switch
The Heater ON/OFF Switch supplies power to the heater
fan and the heater element. When the switch is in the ON
position the heater operates if the thermostat calls for heat.
!NOTE: The fan will continue running even when the
heater is not, when the Heater Switch is in the ON position.
C. 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 temper-
ature, 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 clock-
wise 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 3-Position 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 technical support at 1-888-346-
7539.
!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.

MAINTENANCE
WARNING: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of re, electric
shock or damage to persons.
Glass Cleaning
The glass is cleaned in the factory during the assembly
operation. During shipment, installation, handling, etc., the
front glass panel may collect dust particles; these can be
removed by dusting lightly with a clean dry cloth.
To remove ngerprints or other marks, the front glass panel
can be cleaned with a damp cloth. The front glass panel
should be completely dried with a lint free cloth to prevent
water spots. To prevent scratching, do not use abrasive
cleaners or spray liquids on the clear door surface.
Compact Fireplace Surface Cleaning
Use warm water only to clean painted surfaces of the
Compact Fireplace. Do not use abrasive cleaners.
Servicing
Except for light bulb replacement and cleaning described
above, an authorized service representative should perform
any other servicing.
