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
periodicinspection of 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-

merits for ReliefValvesandAutomatic Gas ShutoffDevicesfor

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. i n.) and a discharge capacitynot 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.)
Yourlocaljurisdictional a uthority,while mandatingtbe useof a
temperature-pressure relief valvecomp,Wying with ANSI 7.21.22
and ASME, may require a valve model differentfrom the one
fomished with the water heater.
Compliancewith suchlocalrequirements 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_, t he relief valvemust not
be mrnovedfrom it'sdesignated openingor plugged.
The temperature-pressure reliefvalvemust be installeddirectly
intothe fittingof the water heaterdesignated for the relief valve.

chargewill exit only within 6 inchesabove,or at any distance
below the structuralfloor. Be certainthat no contactis made

Mocked or reduced in size underany circumstances. Excessive

No valveor other obstruction isto be placedbetweenthe relief
valveand the tank. Do nut connecttubingdirectlyto discharge

ard to life, or propertydamage, t he relief valve mustbe allowed
to discharge water in quantities should circumstances d emand.If
the discharge pipeis not connected to a drain or other suitable
means, t he water flowmaycause propertydamage.
The Discharge Pipe:
Must not be sm_ller in size than the outiot pipe size of
the
valve,or haveany reducing couplings o r other restrictions.
Mustnot be plugged or 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.
A WARNING
The temperature-pressure relief valve must be manually
operated ot least on©ea 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.
