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.
