_I, WARNING
At the time of manufacture th;swater heater was prev;ded
with a combinationtemperaturo-pressurosrelief valve cer-
tified by a nationally recognized testing laboratory that
maintains periodic _nspectlon of production of listedequip-
ment or nnateHais,as meeting the requ_remantsfor Relief
Valvesand Automatic Gas Shutoff Devicesfor Hot Water
Supply Systems, and the current ed_tlonof ANSI Z21.22 •
CSA 4.4 and the code requirements of ASME, If replaced,
the valve must meet the requirements of local codes,but
not less than a €omb;nation temperature and pressure
relief valve ce_t;fiedas meet;ng the requ;romentsfor Relief
Valvesand Automatic Gas Shutoff Devicesfor Hot Water
Supply Systems,ANSI Z21.22 • CSA 4.4 by a natlonaily rec-
ogn;zedtest;ng laboratory that ma;nt_Jns peried;€ iespec-
t;on of productlon of listedequipment or materials.
The valve must be marked wlth a maximum set pressure
not to exceed the nna_kedhydrostati€worklng pressureof
the water heater (150 Ibsdsq,_n,)and a d_sch_mge Cal_€_ty
not lessthan the water heater _nput rate as shownon the
model rating plate. (Electric heaters, watts divided by
1000x 3412 equal BTUIHr, rote,)
Your local jurisdictionala_tberity, while mandatingthe use
of a temperature-pressure relief valvecomplyingwith ANSI
Z21,22 • CSA 4,4 and ASME, may reqmre a valvemodel dif-
ferent from the one furnished with the water heater.
Compl;ancewith such local requirements must be satlsfied
by the installer or end user of the water heater w;th a
locally prescribed temperature.pressure relief valve
;nstelled ;n the deslgnatedopening in the water heater ;n
)laceof the f_tory furnishedvalve,
For safe operation of the water heater,the relief valve must
not be removed from it'sdesignatedopeningor plugged,
The temperaturo.pressuro rel;ef valve must be installed
directly ;nte the fitt;ng of the water heater des;gnatedfor
the relief valve. Pos_tlon the valve downward and provMe
tubing so that any d;sch_urge w;ll exit only with;n 6 inches
above,or at anydistencebelow the struttu_d floor, Be cer-
teln that no contact is made with any I_veelectrical
The d_sch_mge opening must not be blocked or reduced _n
s_ze under any cireumstances, Excessivelength, over 30
feet, or useof more than four elbowscan causerestriction
and reducethe d_sch_urge cap_city of the valve.
No valve or other obsttuct]on_sto be placedbetween the
relief valveand the tanl_ D_o not connecttubing d_rocdy to
dischargedra_n unlessa 6 a_r gap _sprovided,To prevent
bed_ly_njury, h_urd to llfe, or property d_umage, the relief
valve must be allowed to discharge water _n quantities
should €_rcunnst_nces demand. If the dischargep_peis not
connected to a drain or other su_teble means, the water
flow may causeproperty damage.
The D_sch_urge Pipe:
• Must not be smaller in s_zethan the outlet pipe size of
the valve, or have any reducing couplings or other
restHttions,
• Must not be pluggedor blocked,
• Must be of nnateHaiI_sted for hot water distribution,
• Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the d_s-
chargepipe,
• Must terminate at an adequate dra_n,
• Must not have any valve between the relTefvalve and
tenl_
_t, WARNING
The temperature-pressure reNef valve must be manually
operated at least once a year, Caution should be taken to
ensure that (I) no one is _n front of or around the outlet
of the temperatero.pressuro relief valve d_schargeline,
and (2) the water manually dischargedwill not cause any
bed_ly _niury or property damage becausethe water may
be extremely hot.
If after manually operating the valve, it failsto completely
reset and continues to release water, immediately, close
the cold water inlet to the water heater, follow the dra_n-
_n.ginstructions, and replace the temperature.pressure
rehef valvew=th a new one,
