Setting Fan Operation (Fuel) Switch
The fan operation (fuel) switch is preset at the factory in the F
position. See Fig. 11. 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.
