Temperature-Pressure Relief Valve

A WARNING

At the time of manufacturethis water heater was provided with a combinationtemperature-pressuresreliefvalvecertified

by a nationallyrecognizedtesting laboratorythat maintains periodic mspec_onof productionof listedequipmentor mate- rials, as meeting the requirements for Relief Valves and

AutomaticGasShutoffDevicesfor Hot Water SupplySystems, and the latest edition of ANSI Z21.22 and the code require- meritsof ASME.If replaced,the valvemustmeet the require- mentsoflocalcodes,but not lessthan a combinationtempera-

ture and pressurereliefvalvecertifiedas meetingthe require- ments for ReliefValvesandAutomatic GasShutoffDevicesfor

Hot Water SupplySystems,ANSI Z21.22bya nationally recog- nized testinglaboratorythat maintainsperiodicinspectionof productionof listedequipmentor material_

The valvemust be marked wit(1a maximum set pressurenot to exceed the marked hydrostaticworking pressureof the water heater (150 IbsJsqin. .) and a dischargecapacitynot less than the water heater input rate asshownon the modelrating plate. (Electric heaters - watts dividedby 1000 x 3415 equal BTU/Hr. rate.)

Yourlocaljurisdictionalauthority,whilemandating the useof a temperature-pressurereliefvalvecomplyingwith ANSI Z21.22 and ASME, may requirea valvemodeldifferentfrom the one furnishedwith the water heater.

Compliancewith suchlocal requirementsmustbe satisfiedby the installeror enduser of the water heaterwith a locallypre- scribedtemperature-pressurereliefvalveinstalledin the desig-

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

&WARNING

The temperature-pressure relief valve must be manually operated at least once a year. Caution shouldbe taken to

ensurethat (I) no one is in front of or aroundthe outlet of the temperature-pressurereliefvalvedischargeline, and (2) the water manually dischargedwill not cause any bodily injury or property damage because the water may be extremely hot.

ffafter manually operating the valve, it fails.to completely reset and continuesto release watar, immedmatelyclosethe cold water inlet to the water heater, follow the draining

instructions,and replace the temperature-pressure relief valvewith a new one.
