3.7 Install the Isolation Valves

Isolation valves (included with water heater) provide the ability to isolate the water heater from the structure's
plumbing and allow quick and easy access to flush the heat exchanger. The supplied isolation valves meet American
National Standard (ANSI Z21.10.3) / Canadian Standard (CSA 4.3) and are ANSI/NSF 61 approved for potable water.
To install isolation valves:
1. Position the Hot Isolation Valve (Red) below the Hot Outlet side of the water heater.
2. Hand tighten the Swivel Nut of the Hot Isolation Valve (Red) to the Hot Outlet side of the water heater.
3. Rotate the Drain Valve to an accessible position. With a wrench, tighten the Swivel Nut to the water heater.
4. Repeat steps 1 - 3 for the Cold Isolation Valve (Blue).
5. Connect the Cold Isolation Valve (Blue) to the Cold Water Supply Line.
6. Connect the Hot Isolation Valve (Red) to the Hot Water Supply Line.
7. Ensure that both Drain Valves are in the closed position before turning on water supply.
