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 watt­age 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 periodi­cally 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.

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, depending
upon conditions and at least at yearly intervals.

Partially Reective Glass Cleaning

The partially reective glass is cleaned in the factory dur­ing 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ec­tive 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 manu­al, an authorized service representative should perform any
