Setting Fan Operation (Fuel) Switch
The fan operation (fuel) switch is preset at the factory in
the F position. See Fig. 9. This is the correct setting for
most systems. If this system is an electric heat system, set
the switch to the E position. The E setting allows the fan to
turn on immediately with the heating or cooling equipment
in a system where the G terminal is connected.
