How do you figure out the fill pressure for a system. Does it have to do with the longest run in the system? Im running a liberty XL 30 105,000 BTU oil powered burner On a first floor ranch with no upstairs. The longest run is about 215 feet.

    Fill pressure

    You only need enough pressure to lift the water to the highest VERTICAL distance. Horizontal distance has no bearing whatsoever regarding fill pressure.

    12 psi is considered the "norm" and is suitable for up to three floors.
