the heat is turned Off, there
is a 2-minute cool down
period before the fan shuts off
completely.
Remote Operation
The replace is supplied with an
IR multi-function remote control.
!NOTE: To operate correctly, the

General Operation
WARNING: This electric
firebox must be properly
installed before it is used.
This rebox 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 signicantly, 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
continuously while the heater
is on.
