FURNACE CONNECTION
Connections to the furnace are clearly marked.
Return (from the house) are the top ports, Supply (to the house) are the bottom ports. The
installation of isolation valves at both ends of the pump is recommended as well as a valve at the
return line. This will allow you to shut off water supply if repairs or additional heating components are
added to the system. Your main power is connected to the junction box at the back of furnace and
should be connected by a qualified technician.
