PART 6. BOILER PIPING WITH VISION I SYSTEM (DHW PRIORITY WITH OUTDOOR RESET)

A. VISION I SYSTEM PIPING

It is important that the system piping is done correctly when using the Vision 1 System. Follow the piping diagrams 2A through 3G when piping your Munchkin Boiler with Vision I. All general piping practices should still be main- tained.

B.ZONING WITH ZONE VALVES USING VISION I

1.Connect the boiler to the system as shown in piping details 3A through 3C.

2.Connect the DHW circulator (P2) directly to the boiler as shown as shown in the piping details. The boiler circulator (P1) will shut down when there is a DHW demand.

C.ZONING WITH CIRCULATORS USING VISION I

1.Connect the boiler to the system as shown in piping details 4A through 4G.

2.Connect the DHW circulator (P2) directly to the boiler as shown in the piping details. The boiler circulator (P1) will shut down when there is a DHW demand.
