    Steam or hot water? If hot water, make up valve is left open all the time. If steam, there should be a water level mark on boiler jacket behind sight glass. If there isn't, usually half to two-thirds up the sight glass is fine. But maybe not. Best I can tell you.

    its a water system.Make up valve? Is that the valve releasing the house line to the boiler. That valve is before the pressure reducing valve, then there is a valve with a pipe going to the floor.And then into a tee which goes up to the expansion tank and then the air vent valve, the other way of the tee goes into the boiler.
