FAN OPERATION
The accessory fan is wired in series with a speed con-
trol switch and a temperature sensor switch. Set the
speed control to an "ON" position and light the heater.
The temperature sensor switch will automatically start
the fan when the switch warms up—and stop the fan
when it cools down. You can manually stop the fan by
turning the speed control switch to "OFF". See Figure
11 for fan wiring diagram.
