Operation
Figure 1
General Operation
WARNING: This electric firebox must be properly in-
stalled before it is used.
This firebox operates with Comfort$averTM technology,
which automatically adjusts the fan speed and heater watt-
age to safely and precisely match the requirements of the
room based on the thermostat setting. The heater operates
such that once the room reaches the set point, the fan and
heater will continuously run at a low level, to maintain the
desired room temperature. If the temperature in the room
rises significantly, i.e. sun coming through a window or a
central furnace turns on, the heater will turn off and periodi-
cally turn back on to circulate the air around the unit, until
the room temperature drops and requires the heater to be
constantly on again.
!NOTE: The unit is designed so that the fan will run con-
tinuously while the heater is on.
!NOTE: The element retains heat after shutdown, there is
a built in cool down period of 2 minute before the fan shuts
off completely, when the heat function is turned Off.
Remote Operation
The replace is supplied with an IR multi-function remote
control.
!NOTE: To operate correctly, the remote control must be
pointed towards the front of the unit.
Controls
The unit can be controlled by either the manual controls
which are located on the upper right of the replace or the

set to when it was turned O󰀨 and the intake temperature
will be indicated on the Display.
!NOTE: When any button is pressed on the unit the
intake temperature will be displayed on the Display for 7
seconds.

Maintenance
 WARNING: Disconnect power and allow heater to
cool before attempting any maintenance or cleaning to
reduce the risk of re, electric shock or damage
to persons.
!NOTE: The replace should not be operated with an
accumulation of dust or dirt on or in the unit, as this can
cause a build up of heat and eventual damage. For this
reason the heater must be inspected regularly, depend-
ing upon conditions and at least at yearly intervals.
Partially Reective Glass 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 described in this manu-
al, an authorized service representative should perform any
other servicing.
