Installing the Water Pump
Remove the cover on the pump. Then using an approved wire, connect the ground wire to the green ground screw
on the pump. Connect the black wire to the yellow wire on the pump. Finally, connect the remaining two white
wires together and replace the pump cover.
The pump must be able to deliver 10-12 GPM of flow in one inch line to ensure the heat from the boiler can be
properly delivered to the heating zones. The target temperature change between the supply and return line is 20°F
under max draw. Return water temperature must remain above 140° during operation to prevent condensation.
An expansion tank must be installed on the system along with an air bleeder. The expansion tank must be properly
sized for the complete water volume in the entire heating system. Pressure relief valves come installed from the
factory. An air bleeder or pressure relief valve must be installed on the water tank. A pressure gauge may be in-
stalled on the boiler.
It is recommened to install the pump inside the building that the boiler is serving.
WARNING: Do Not install close off valves on the boiler, closing of the loop while in operation can create danger
-
ous conditions. Follow all state and local codes for installing a pressurized system.
Note: The wires from the pump will have to connect with the main power wires in a junction box.
Note: The pump must run continuously whenever the WoodMaster Boiler is in use. DO NOT run the
pump dry.
Note: All wiring must follow state and local codes and should be done by a qualified electrician. Disconnect
power before servicing any electrical components.
All water lines on the boiler loop must be 1” in size and the boiler loop must be installed in a way that will not
allow excessive pressure to develop in the system.
