Relief Valve
AWARNING
I
At the time of manufacture this water heater was provided
with a combinationtemperature-pressures relief valve cer-
tified by a nationally recognized testing laboratory that
maintains periodic inspectionof production of listedequip-
ment or materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devicesfor Hot Water
SupplySystems,and the latest edition of ANSI Z21.22 and
the code requirements
of ASME. If replaced, the valve
must meet the requirements of local codes, but not less
than a combination temperature and pressurerelief valve
certified as meeting the requirements for Relief Valvesand
Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22 by a nationally recognized testing
laboratory that maintains periodic inspectionof production
of listedequipment or materials.
The valve must be marked with a maximum set pressure
not to exceed the marked hydrostaticworking pressureof
the water heater (150 Ibs./sq.in.) and a dischargecapacity
not lessthan the water heater input rate as shownon the
model rating plate. (Electric heaters - watts divided by
1000x 3415 equal BTU/Hr. rate.)
Your localjurisdictional authority, while mandatingthe use
of a temperature-pressure relief valve complying with
ANSI Z21.22 and ASME, may require a valve model differ-
ent from the one furnishedwith the water heater.
Compliance with suchlocal requirements must be satisfied
by the installer or end user of the water heater with a
locally prescribed temperature-pressure
relief valve
installed in the designatedopening in the water heater in
place of the factory furnishedvalve.
For safe operation of the water heater, the relief valve
must not be removed from it's designated opening or
plugged.
The temperature-pressure relief valve must be installed
directly into the fitting of the water heater designatedfor
the relief valve. Positionthe valve downward and provide
tubing so that any dischargewill exit only within 6 inches
above,or at any distancebelow the structural floor. Be cer-
tain that no contact is made with any live electrical part.
The dischargeopening must not be blocked or reduced in
size under any circumstances. Excessivelength, over 30
feet, or useof more than four elbowscan causerestriction
and reducethe dischargecapacityof the valve.
No valve or other obstruction is to be placed between the
relief valve and the tank. Do not connecttubing directly to
dischargedrain unlessa 6" air gap is provided.To prevent
bodily injury, hazard to life, or property damage,the relief
valve must be allowed to discharge water in quantities
should circumstancesdemand. If the dischargepipe is not
connected to a drain or other suitable means, the water
flow may causeproperty damage.
The DischargePipe:
Must not be smaller in size than the outlet pipe size of
the valve, or have any reducing couplings or other
restriction.
Must not be pluggedor blocked.
Must be of material listedfor hot water distribution.
Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the dis-
chargepipe.
Must terminate at an adequatedrain.
Must not haveany valvebetween the raliefvalveand tank.
AWARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that (I) no one is in front of or around the outlet
of the temperature-pressure relief valve 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 manually operating the valve, it fails to completely
reset and continues to release water, immediately, close
the cold water inlet to the water heater, follow the drain-
ing instructions, and replace the temperature-pressure
relief valve with a new one.
