Water Piping Diagrams

Before installation of water piping review the following:

1.See Mixing Valves on page 14.

2.See Dishwashing Machines on page 14.

3.See Temperature-Pressure Relief Valve on page 15.

TWO WATER HEATERS, SINGLE TEMPERATURE WITH BUILDING RECIRCULATION

4.See Closed Systems and Thermal Expansion on page 14

5.See Water Line Connections on page 40.

6.If a pump is being installed between a water heater and storage tank or on a building recirculation loop wire according to Figure 63 on page 66.

7.If a pump is being installed in a recirculation loop between the water heater and a commercial dishwasher wire according to Figure 63 or Figure 64 on page 66.
