Speed Control and Temperature Switch Are Used
Ignite the fire in the firebox or appliance with the variable
speed control switch in an “ON” position. The fan will auto

of firebox or appliance installation, outside air temperature
vs. inside air temperature) can contribute to the length of
the time the fan remains on after the firebox or appliance
is turned OFF. The fan can be turned off manually with the

compartment. Remove any dust, dirt or obstructions as di
