Temperature-Pressure Relief Valve

A, WARNING

At the time of manufacture this water heater was provided

with a comb_nat;_nm_ratu_--,_ures relief valvecerti_d by a nationally recognized testing laboratory that maintains periodicinspectionof productionof listedequipmentor mate- rials, as meeting the requirements for Relief Valves and Automatic Gas ShutoffDevicesfor Hot Water SupplySystems, and the latest edition of ANSI Z21.22 and the code require- ments of ASME. If replaced,the valve must meat the require- ments of localcedes,but not lessthan a combinationtempera.

ture andpressurerelief valvecertified as meeting the _luire- merits for ReliefValvesandAutomatic Gas ShutoffDevicesfor

Hot Water SupplySystems, AHSLZ2.Z2 by a nationallyrecog. nized testing laboratory that maintainsperiodic inspectionof productionof llstedequipment or materials.

The valve must be made:d with a maximum set presserenot to exceed the marked hydrostatic working pressureof the water heater (I 50 IbsJsq.in.) and a dischargecapacitynot less than the water heater input rate as,shownon the model rating plate. (Electric heaters • watts divided by 1000 x 3415 equal BTU/I-Ir. rate.)

Yourlocaljurisdictionalauthority,while mandatingtbe useof a temperature-pressurerelief valvecomp,Wyingwith ANSI 7.21.22 and ASME, may require a valve model differentfrom the one fomished with the water heater.

Compliancewith suchlocal requirements must be satisfiedby the installeror end userof the water heater with a locallypre-

scribed temperature-pressure relief valveinstalledin the desig- natecl openingin the water heater in placeof the factory fur- nishedvalve.

For safeoperationof the water heate_,the relief valvemust not be mrnovedfrom it'sdesignatedopeningor plugged.

The temperature-pressurereliefvalvemust be installeddirectly intothe fittingof the water heaterdesignatedfor the relief valve.

No valveor other obstructionisto be placedbetweenthe relief valveand the tank. Do nut connecttubingdirectlyto discharge drainunlessa 6" air gapisprovided.Topreventbodilyinjury,haz- ard to life, or propertydamage,the relief valve mustbe allowed to dischargewater in quantitiesshouldcircumstancesdemand.If the dischargepipeis not connectedto a drain or other suitable means,the water flowmaycausepropertydamage.

The DischargePipe:

Must not be sm_ller in size than the outiot pipe size of the

valve,or haveany reducingcouplingsor other restrictions. Mustnot be pluggedor blocked.

Mustbe of material listedfor hot water distribution.

Must be installedso as to allow complete drainageof both

the temperature-pressure relief valve, and the discharge

pipe.

Must terminate at an adequatedrain.

Mustnot haveany valvebetweenthe relief valveand tank.

AWARNING

The temperature-pressure relief valve must be manually operated ot least on©e a year, Cantion shoukl be taken to onsore that (I) no one is in front of or around the oudet of the temperoture-peessurerefiofvalve dischargeline, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.

If after manually operating the valve, it fails to completely reset and continuesto releasewater_immediately dose the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valvewlth a new ane.
