NOTES:

1.This drawing is meant to show system piping concept only.

Installer is responsible for all equipment & detailing required by local codes.

2.All closely spaced tees shall be within 4 pipe diameter center to center spacing.

3.A minimum of 6 pipe diameters of straight pipe shall be installed upstream and downstream of all closely spaced tees.

4.The minimum pipe size for connecting a Super Stor water heater is 1 inch.

5.The minimum pipe size for connecting a Munchkin boiler shall be 1.25 inches and 2 inches for the 399M.

6.All pumps are shown with isolation flanges and integral flow check valves.

The alternative is standard flanges with full port ball valves and a separate flow check valve.

7.The anti-scald mixing valve is recommended if the DHW temperature is set above the factory setting of 119˚F.

8.Install a minimum of 12 diameters of straight pipe upstream of all circulators.

9.A purging valve may be used in lieu of the ball valve / hose bib combination shown.

10.High temperature loads cannot operate simultaneously with low temperature loads.

11.Supply water temperature to high temperature loads is not reset based on outdoor temperature.

12.Domestic water heating is highest priority load, and controlled through priority zone of multi-zone relay center
