Temperature-Pressure Relief Vave

AWARNING

At the time of manufacturethis water heater was provided with a combinationtemperetum-pressuresreliefvalvecertified _" a nationally.recognizedtesting I.aboratorythat maintains

._riodlcinspectionof productionof hstedequipmentor mate- rials, as meeting the requirements for Relief Valves and

AutomaticGas ShutoffDevicesfor Hot Water SupplySystems, and the latest edition of ANSI Z21.22 and the code require- mentsof ASME. If replaced,the valvemustmeet the require- mentsof localcodes,but not lessthan a combinationtempera- ture and pressurerelief valvecertifiedas meodngthe require- mentsfor ReliefValvesand AutomaticGas ShutoffDevicesfor Hot Water SupplySystems,ANSI 7-21.22bya nationally recog- nized tesdnglaboratorythat maintains periodicinspectionof

The valve mustbe m_(ed with a maxmmumset pressurenot to exceed the marked hydrostaticworking pressure of the water heater (150 IbsJsqin. .) and a dischargecapacitynot less than the water heater input r_e asshownon the modelrating plate. (Electric heaters - watts dividedby 1000 x 3415 equal BTU/Hr. rate.)

Yourlocaljurisdictionalauthority, whitemand_ingthe useof a temperature-pressurereliefwdve complyingwith ANSI Z21.22

and ASME, may require a valvemodel differentfrom the one fornished with the water heater.

Compliancewith suchlocalrequirementsmust be satisfiedby the installeror end useroftbe water heater with a locallypre- scribedtemperature-pressurereliefvalveinstalled in the deslg-

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

For safeoperationofthe water heater,the reliefvalvemust not be removed from it'sdesignatedopeningor plugged.

The temperature.pressurereliefvalvemustbe installeddirectly

A,WARNING

The temperature.pressure relief valve must be manually operated at least once a yea_ C_udon shouldbe taken to ensurethat (I) no one is in front of or aroundthe outlet of

the temperatum-preasure relief valvedischargeline, and (2) the water manually dischargedwill not causeany bodily

injury or property damage because the water may be extxemelyhot.

ffafter manually operating the valve, it failsto completely reset and continues to releasewater, immediatelyclosethe cold water inlet to the water heater, follow the draining

instructions, and replace the temperature-pressure relief

valve with a new one.

RELIEFVALVE OPENING

At the time of manufacture,this water heater was provided with a combinationtern-

perature-pressure relief valve listed as complying with the standard for relief valves and automatic gas shut-off devicesfor hot water supply systems,ANSI Z21.22. For safeoperation of the water heaten the relief valve must not be removed from its des-

ignatedpoint of installationor plugged.

Your local jurisdictional authority, while mandatingthe use of a temperature-pressure

relief valve complyingwith ANSI Z2h22 and ASME, may require a valve model differ- ent from the one furnished with the water heater.

Compliancewith such local requirements must be satisfied by the instaberor end user of the water beater with a locally prescribed temperature-pressure reFief valve installedin the designated opening in the water heate_

See manual heading.'%mperature-Pressure Relief Valves"for installationand maint_

nance of relief valve,discharge line, andother safetyprecautions.
