Recommended Operating Procedures When Variable
Speed Control and Temperature Switch Are Used
Ignite the re in the replace with the variable speed control
switch in an "ON" position. The fan will automatically turn
on when the temperature sensor switch closes at approximately 110O F. Heated air should be delivered at the outlet
grille. The fan will continue to operate after the replace is
turned OFF until the sensor switch opens.
Various conditions (such as replace model, type of replace installation, outside air temperature vs. inside air
temperature) can contribute to the length of the time the
fan remains on after the replace is turned OFF. The fan
can be turned off manually with the speed control switch.
WARNING! Risk of Injury! DO NOT contact fan blades
during operation.
Maintenance
Periodically check the fireplace louvers, if present,
and controls compartment. Remove any dust, dirt or
obstructions as directed in the appliance Owner's Manual.
