    The fan should turn on when the burner turns on only. You don't want the fan running when the burner is off. That just pulls energy out of the boiler and sends it up the chimney.

    That fan in the can should connect directly to the burner circuit.

    The whole purpose of a fan in the can is to provide fresh air to the burner when it runs. I am confused. Why would you use it for one zone only?

    Why?

    What type of equipment, gas or oil? The manufacturer has an easy wiring diagram for either.
    Like John said, it's wired in as and intended to be a safety. No fan proving, no burner firing.
