Blower Operation
Model 2302
The automatic fan switch turns on the blower after the furnace
has been operating a few minutes and turns off the blower after
the furnace shuts off. The blower will not operate unless the
fan switch (pull chain) is pulled to the "ON" position, either
"HIGH" or "LOW". To check the fan switch (pull chain) position,
tum the automatic fan switch dial to 70, then pull the chain on
the fan switch to obtain the high, low or off position. Set the
automatic fan switch dial to 110 and readjust it higher or lower
as necessary to obtain blower operation within 4 to 5 minutes
after the furnace burner is in operation.
Model 2303
You must select "ON" for continuous blower operation or
"AUTO" for automatic blower operation. If blower is set on
"AUTO" when the furnace heats up, the heat sensor switch is
activated and the blower will turn off. The blower will not
operate if the fan switch is set in the "OFF' (center) position.
