General Operation
WARNING: This electric
firebox must be properly installed
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 re-
quirements 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 tempera-
ture 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 continuously
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 func-

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 accumu-
lation 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 a mini-
mum yearly intervals.
Partially Reective Glass
Cleaning
The partially reective glass is
cleaned in the factory during the
assembly operation. During ship-
ment, 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 clean-
ing described in this manual,
an authorized service repre-
sentative should perform any
other servicing.
