Temperature-Pressure Relief Valve
a, WARNING
At the time of manufacturethis water heater was provided
with a combination temperature-pressures reliefvalvecertified
by a nationally recognizedtesting laboratory that maintains
periodicinspection of production of listedequipmentor mate-
rials, as meeting the requirements for Relief Valves and
_utomatic GasShutoffDevices for Hot Water Supply Systems,
md the latest edition of ANSI Z21.22 and the code require.
_ents of ASME. If replaced, the valvemust meet the require-
_ents of localcodes,but not lessthan a combination tempera-
pureand pressure relief valvecertifiedas meetingthe require-
mentsfor ReliefValvesand Automatic GasShutoffDevices for
Hot Water Supply Systems, ANSI Z21.22 bya nationally recog-
nizedtestinglaboratory that maintains periodic inspection of
pTreduction of listedequipmentor materials.
he valvemust be marked with a maximum set pressure not
to exceed the marked hydrostaticworking pressureof the
water heater (150 Ibsdsq, i n.) and a discharge capacitynot less
thanthe water heater input rate as shown on the modelrating
plate. (Electric heaters- watts dividedby 1000x 3415 equal
BTU/Hr. rate.) .
Yourlocaljurisdictional author_y,while mandating the useof a
temperature-pressure r elief valvecomplying with ANSI Z21.22
and ASME, may require a valvemodel differentfrom the one
furnished with the water heater.
Compliancewith suchlocalrequirementsmust be satisfied by
the installeror end userof the water heater with a locally p,re-
scribed temperature-pressure relief valveinstalledin the desig-
nated openingin the water heater in placeof the factory fur.

means, t he water flowmaycause propertydamage.
• e Discharge Pipe:
Must not be smallerin sizethan the outlet pipesize of the
valve,or haveany reducing couplings o r other restrictions.
Mustnot be plugged or Mocked.
Mustbe of materiallistedfor hot water distribution.
Must be installedso as to allow completedrainageof beth
the temperature-pressure relief valve, and the discharge
pipe.
Mustterminate at an adequatedrain,
Must not haveanyvalvebetween the relief valveand tank.
AWARNING
The temperature-pressure relief valve must be manuall:
operated at least once a year Caution shouldbe taken tt
! ensurethat (I) no one is in front of or aroundthe outlet o
the temperature-pressure relief vaJve discharge line, and (2)
the water manually dischargedwill not cause any bodily
injury or property damage because the water may be
extremely hot.
If after manual.lyoperating the valve, it fails, t o completely
reset and continuesto release water, immediately closethe
cold water inlet to the water heater, follow the draining
instructions, and replace the temperature-pressure relief
valvewith a new one.
