Relief Valve

A WARNING

At the time ofmanufacture thiswater heaterwas providedwith a combinationtemperature-pressuresreliefvalvecertifiedby a nationallyrecognizedtestinglaboratorythat maintainsperiodic inspectionof productionof listedequipment or materials,as meetingthe requirementsfor ReliefValvesand AutomaticGas ShutoffDevicesfor Hot Water SupplySystems,and the latest edition of ANSI Z21.22 and the code requirements of ASHE. If

replaced,the valvemustmeet the requirementsof localcodes but not lessthan a combinationtemperature andpressurerelief valvecertifiedasmeetingthe requirementsfor ReliefValvesand

AutomaticGasShutoffDevicesfor Hot Water SupplySystems, ANSI Z21.22 by a nationally recognizedtestinglaboratorythat

maintainsperiodicinspectionof productionof listedequipment or materials.

The valvemust be markedwith a maximum set pressurenot to exceed the marked hydrostaticworking pressure of the

water heater (150 Ibsdsq.in.) and a dischargecapacity not lessthan the water heater input rate as shownon the model

rating plate.(Electric heaters - watts dividedby 1000x 3415 equalBTU/Hr. rate,)

Yourlocaljurisdictionalauthority,while mandatingthe useof a temperature-pressurereliefvalvecomplyingwith ANSI Z21.22 and ASME,mayrequire a vane model differentfrom the onefur- nishedwith the water heater.

Compliancewith suchlocalrequirements must be satisfiedby the installeror end user of the water heater with a locallypre- scribed temperature-pressurereliefvalveinstalledin the desig-

natedopeningin the water heater in placeof the factoryfur- nishedvalve.

Forsafeoperationofthe water heater,the reliefvalvemustnot

beremovedfrom it'sdesignatedopeningor plugged.

The temperature-pressurereliefvalvemustbe installeddirectly intothe fittingofthe water heaterdesignatedfor the relief valve. Positionthe valvedownwardand providetubing sothat anydis-

chargewill exit onlywithin 6 inchesabove,or at any distance belowthe structuralfloor.Be certainthat no contactis made

with anyliveelectricalpart. The dischargeopeningmustnot be blockedor reduced in sizeunder anycircumstances. Excessive length,over30 feet, or useof more than four elbowscan cause restriction andreducethedischargecapacityofthe valve.

No valveor other obstructionisto be placedbetween the relief valveand the tank. Do not connecttubingdirectlyto discharge drain unlessa 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

i other suitable means, the water flow may cause property damage.

:The DischargePipe:

:Must not be smallerin sizethan the outlet pipesizeofthe valve,or haveanyreducing couplingsor other restrictions. Must not be pluggedor blocked.

•Must be of material listedfor hot water distribution.

!Must be installedsoasto allow completedrainageof both

the temperature-pressurereliefvalve, and the discharge pipe.

tMustterminate at an adequatedrain.

Mustnot haveanyvalvebetween the rolief valveand tank.

&WARNING

The temperature-pressure relief valve must be manually operated at least once a year. Caution should be 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 cause any bodily injury or property damage becausethe 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 drain-

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