Operation
Filling With Water
Connect a garden hose between a domestic water supply and the furnace fill valve (0020-275), which was installed in the cold water
return line at a point just prior to its exiting the building. Make sure that valves not being used on the furnace are closed and the valves
that are being used are open. Begin filling and inspect for leaks on all fittings. Repair any leaks that are found.
Routinely pay attention to the water level light. If the light is not lit, this indicates that the water level is low and the furnace may need
to have water added. Add water until it flows out of the vent pipe.
Bleeding The System
While filling the boiler, close the cold water return valve on the furnace for two or three minutes, and then open the valve. This will
force trapped air out of the hot water supply line. Repeat this process with the hot water supply valve on the furnace to force air out of
the cold water return line. Once both lines have been “bled” continue filling the furnace until the system is full and water comes out of
the vent pipe.
CAUTION!!!
Feed and return valves that are not being used must be insulated
or removed to prevent freezing and breaking.
CAUTION!!!
Air in the water lines can cause damage to the pump.
