The valvemust be marked with a maximum set pressurenot to exceed the marked hydrostaticworking pressureof the water heater (150 IbsJsq.in.) and a dischargecapEt'm/nut lessthan the water heater input rate as shownon the model rating plate. (Electric heaters - watts dividedby 1000x 3415 equal BTU/Hr. rate.)

YourlocaljurirKl_ anthorit_ whilemandatingthe useof a

temperature-pressurereliefvalvecomplyingwith ANSI Z21.22 andASME,may requirea valvemodeldifferentfromthe onefur- nishedwiththe waterhe,_er.

Compliancewith suchlocalrequirementsmust be satisfiedby the installeror end userof the water heaterwith a locallypre- scribedtemperature-pressurereliefvalveinstalledin the desig-

nated openingin the water heater in placeof the factory fur- nishedvalve.

For safeoperationof the water heater,the reliefvalvemustnot beremovedfrom it'sdesignatedopeningor plugged.

The temperature-pressurereliefvalvemustbe installeddirectly intothe fittingofthe water heaterdesignatedfur the reliefvabe. Positionthe valvedownwardand providetubingsothat anydis-

chargewill exit onlywithin 6 inches above,or at any distance belowthe structuralfloor.Be certainthat no contact ismade

with anyliveelectricalpart.The dischargeopeningmust not be blockedor reducedin size underany circumstancesExcessive. length,over30 feet, or useof more than fourelbowscan cause restrictionand reducethe dischargecapacityofthe valve.

No valveor other obstructionisto be placedbetweenthe relief valveand the tank. Do not connecttubingdirectlyto discharge drain unless a 6" air gap is provided.To preventbodilyinjury,

hazard to life, or property damage,the relief valve must be allowedto dischargewater in quantitiesshouldcircumstances demand.If the dischargepipe is not connectedto a drain or other suitable means, the water flow may causeproperty damage.

The DischargePipe:

•Must nnt be smallerin sizethan the outlet pipe sizeof the valve,or haveanyreducingcouplingsor other restrictions.

•Must not be pluggedor blocked.

•Must be of material listedfor hot water distribution.

•Must be installedso as to allow complete drainageof buth the temperature-pressurereliefvalve, and the discharge pipe.

Must terminate at an adequatedrain.

[_ Mustnot haveanyvalvebetween the relief valveandtank.

AWARNING

The temperature-pressure relief valve must be manually operated at least once a year. Caution shouldbe taken to I ensure that (I) no one is in from: of or around the outlet of the temperature-pressure relief valve discharge line,

md (2) the water manually dischargedwill not causeany )odily iniuP/ or property damage becausethe water may

)e extremely hot.

If after manually operating the valve, it failsto completely reset and continues to release water, immediately, close the cold water inlet to the water heater, follow the drain-

ing instructions, and replace the temperature-pressure relief valve with a new one.
