Temperature-Pressure Relief Valve

This heater is provided with a properly certiﬁ ed combination

temperature - pressure relief valve by the manufacturer.

The valve is certiﬁ ed by a nationally recognized testing laboratory

that maintains periodic inspection of production of listed equipment

of materials as meeting the requirements for Relief Valves for Hot

Water Supply Systems, ANSI Z21.22 • CSA 4.4, and the code

requirements of ASME.

If replaced, the valve must meet the requirements of local codes,

but not less than a combination temperature and pressure relief

valve certiﬁ ed as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to

exceed the marked hydrostatic working pressure of the water

heater (150 psi = 1,035 kPa) and a discharge capacity not less

than the water heater input rate as shown on the model rating plate.

(For electric heaters, watts x 3.412 equals Btu/hr input rate)

For safe operation of the water heater, the relief valve must not be

removed from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly

into the ﬁ tting of the water heater designed for the relief valve.

Position the valve downward and provide tubing so that any

discharge will exit only within 6 inches (153 mm) above, or at any

distance below the structural ﬂ oor. Be certain that no contact is

made with any live electrical part. The discharge opening must

not be blocked or reduced in size under any circumstances.

Excessive length, over 30 feet (9.14 m), or use of more than four

elbows can cause restriction and reduce the discharge capacity

of the valve.

No valve or other obstruction is to be placed between the relief

valve and the tank. Do not connect tubing directly to discharge

drain unless a 6 inch air gap is provided. To prevent bodily

injury, hazard to life, or property damage, the relief valve must

be allowed to discharge water in quantities should circumstances

demand. If the discharge pipe is not connected to a drain or other

suitable means, the water ﬂ ow may cause property damage.

The Discharge Pipe:

• Shall not be smaller in size than the outlet pipe size of the

valve, or have any reducing couplings or other restrictions.

• Shall not be plugged or blocked.

• Shall be of material listed for hot water distribution.

• Shall be installed so as to allow complete drainage of both the

temperature-pressure relief valve, and the discharge pipe.

• Shall terminate a maximum of six inches above a ﬂ oor drain or

external to the building. In cold climates, it is recommended

that the discharge pipe be terminated at an adequate drain

inside the building.

• Shall not have any valve between the relief valve and tank.

The temperature-pressure relief valve must be manually operated

at least once a year. Caution should be taken to ensure that

(1) no one is in front of or around the outlet of the temperature-

pressure relief valve discharge line, and (2) the water manually

discharged will not cause any bodily injury or property damage

because the water may be extremely hot.

If after manually operating the valve, it fails to completely reset

and continues to release water, immediately close the cold water

inlet to the water heater, follow the draining instructions, and

replace the temperature-pressure relief valve with a new one.
