Fan Control
The fan control is a non-adjustable automatic type. The fan control
will require between 5 and 10 minutes of main burner operation
before the fan control "closes" and activates the blower. The blower
will continue to run between 5 and 10 minutes after the main
burner shuts off, before the fan control "opens" and deactivates
the blower.
