1.This drawing is meant to show system piping concept only.
Installer is responsible for all equipment & detailing required by local codes.
2.Adjust differential pressure bypass valve to eliminate any flow velocity noise when zone with highest pressure drop operates by itself.
3.The minimum pipe size for connecting a Super Stor water heater is 1 inch.
4.The minimum pipe size for connecting a Munchkin boiler is 1.25 inches.
5.All pumps are shown with isolation flanges. The alternative is standard flanges with full port ball valves.
6.The
7.Install a minimum of 12 diameters of straight pipe upstream of all circulators.
8.A purging valve may be used in lieu of the ball valve / hose bib combination shown.
9.A minimum of 6 pipe diameters of straight pipe shall be installed upstream and downstream of all closely spaced tees.
