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.Adjust 3-way manually-set mixing valve to yield proper supply temperature to lower temperature load.
