Installation Instructions

Temperature-Pressure

Relief Valve

_,WARNING

At the time of manufacture this water heater was provid- ed with a combination temperature-pressures relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed

equipment or materials, as meeting the requirements for

Relief Valves and Automatic Gas Shutoff Devices for Hot

Water Supply Systems, and the latest edition of ANSI Z21.22 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 SupplySystems,ANSI Z21.22 bya nationallyrecog- nized testing laboratory that maintains periodic inspection of production of listed equipment or materials.

The valve must be marked with a maximum set pressure not to exceed the marked hydrostaticworking pressureof the water heater (150 Ibs./sq.in.) and a dischargecapacity not lessthan the water heater input rate as shownon the model rating plate. (Electric heaters - watts divided by 1000 x 3415 equal BTU/Hr. rate.)

Your localjurisdictionalauthority, while mandatingthe use of a temperature-pressure relief valve complying with

ANSI Z21.22 and ASME, may require a valve model differ- ent from the one furnishedwith the water heater.

Compliance with such local requirements must be satis- fied by the installer or end user of the water heater with a locally prescribed temperature-pressure relief valve installed in the designatedopening in the water heater in daceof the factory furnishedvalve.

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 designatedfor the relief valve. Position the valve downward and provide tubing so that any dischargewill exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical )art. The discharge opening must not be blocked or

reduced in size under any circumstances.Excessivelength, over 30 feet, or use of more than four elbows can cause restriction and reduce the dischargecapacityof the valve.

No valve or other obstruction is to be placedbetween the relief valve and the tank. Do not connecttubingdirectly to dischargedrain unlessa 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 shouldcircumstancesdemand. If the dischargepipe is not connected to a drain or other suitable means, the water flow may causeproperty damage.

The DischargePipe:

•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 pluggedor blocked.

Must be of material listedfor 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 haveanyvalvebetweenthe relief valveand tank.

•, 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 valvewith a new one.
