Installation Instructions

Temperature-Pressure

Relief Valve

_,WARNING

At the time of manufacture this water heater was provided with a combination temperature-pressuras relief valve cer- tiffed by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equip-

ment or materials, as meeting the requirements for Relief

Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, and the current edition of ANSI Z21.22 , CSA 4.4 and the code requirements of ASHE. If replaced, the valve must meet the requirements of local codes, but

not less than a combination temperature and pressure

relief valve certified as meeting the requirements for Relief

Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, CSA 4.4 by a nationally rec- ognized testing laboratory that maintains periodic inspec- tion of production of listed equipment or materials.

The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 Ibs. p.s.i.) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr. rate.)

Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI

Z21.22, CSA 4.4 and ASME, may require a valve model dif- ferent from the one furnished with the water heater.

Compliance with such local requirements must be satisfied by the installer or end user oftbe water heater with a local- ly prescribed temperature-pressure relief valve installed in the designated opening in the water heater in place of the factory furnished valve.

For safe operation of the water heater, the relief valve must not be removed from it'sdesignated opening or plugged.

The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be cer- tain 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, 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" 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 flow may cause property damage.

The Discharge Pipe:

Must not be smaller in size than the outlet pipe size of

the valve, or have any reducing couplings or other restriction.

Must not be plugged or blocked.

Must be of material listed for hot water distribution.

Must be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the dis- charge pipe.

Must terminate at an adequate drain.

Must not haveany valve between the relief valve and tank.

(cont'd)

&WARNING

The temperature-pressure relief valve must be manually operated at least once a year. Caution shouldbe taken to ensure that (I) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) the water manually dischargedwill not causeany bodily injury or property damage becausethe water may be extremely hot.

If after manually operating the valve, it fails to complete- ly reset and continues to release water, immediately, close the cold water inlet to the water heater, follow the

draining instructions, and replace the temperature-pres- sure relief valve with a new one.
