For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked “T & P RELIEF VALVE” (see Figure 14). This valve must be design certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of listed equipment or materials as meeting the requirements for Relief Valves and Automatic Shut-off Devices for Hot Water Supply Systems, ANSI Z21.22. The function of the temperature and pressure relief valve is to discharge water in large quantities in the event of excessive temperature or pressure developing in the water heater. The valve's relief pressure must not exceed the working pressure of the water heater as stated on the data plate.

Important: Only a new temperature and pressure relief valve should be used with your water heater. Do not use an old or existing valve as it may be damaged or not adequate for the working pressure of the new water heater. Do not place any valve between the relief valve and the tank.

The Temperature & 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 6 inches above a floor 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.
