WIRING DIAGRAM
The Temperature and Pressure Relief Valve:
• Must not be in contact with any electrical part.
• Must be connected to an adequate discharge line.
• Must not be rated higher than the working pressure
shown on the data plate of the water heater.
The Discharge Line:
• Must not be smaller than the pipe size of the relief
valve or have any reducing coupling installed in the
discharge line.
• Must not be capped, blocked, plugged or contain any
valve between the relief valve and the end of the
discharge line.
• Must terminate a maximum of six inches above a
fl oor drain or external to the building.
• Must be capable of withstanding 250°F (121°C)
without distortion.
• Must be installed to allow complete drainage of both
the valve and discharge line.
IMPORTANT: Do not use an extension cord to connect the
water heater to an electrical outlet.

NOTE: Always reference the wiring diagram for the correct
electrical connections.
After making all electrical connections, completely fill the
tank with water and check all connections for leaks. Open
the nearest hot water faucet and let it run for 3 minutes to
purge the water lines of air and sediment and to ensure
complete filling of the tank. The electrical power may then
be turned on. Verify proper operation after servicing.
