Relief Valve
AWARNING
At the time of manufacture this water heater was provided
with a combination temperature-pressures relief vai ve cer­
tified by a nationaiiy recognized testing iaboratory that
maintains periodic inspection of production of listed equip­
ment or materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, 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 pressure relief valve
certified as meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z2I.22 by a nationally recognized testing
lAoratory that maintains periodic inspection of production
of listed equipment or materials.
The valve must be marked with a maximum set pressure
not to exceed the marked hydrostatic working pressure of
the water heater (ISO lbs./sq. in.) and a discharge capacity
not less than the water heater input rate as shown on the
model rating plate. (Electric heaters - watts divided by
1000 X 3415 equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use
of a temperature-pressure relief valve complying with
ANSI Z2I.22 and ASME, may require a v^ve model differ­
ent from the one furnished with the water heater.
Compliance with such local 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 designated opening in the water heater in
place of the factory furnished valve.
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 designated for
the relief valve. Position the valve downward and provide
tubing so that any discharge wll exit only within 6 inches
above, or at any distance below the structural floor. Be cer­
tain that no contact is made with any live electrical part.
The discharge opening must not be blocked or reduced in
size under any circumstances. Excessive length, over 30
feet, or use of more than four elbows can cause restriction
and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the
relief valve and the tank. Do not connect tubing directly to
discharge drain unless a 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 circumstances demand. If the discharge pipe is not
connected to a drain or other suitable means, the water
flow may cause property damage.
The Discharge Pipe:
*
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 plugged or blocked.
* Must be of material listed for hot water distribution.
■ Must be installed so as to allow complete drainage of
both the temperature-pressure relief valve, and the dis­
charge pipe.
* Must terminate at an adequate drain.
* Must not have any valve between the relief valve and
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 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 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.

WARNING “RELIEF VALVE OPENING
This water heater is provided with a cwriJinalion Temperature-Pressyre Relief Valve listed as iXHrtíyiiw with
standard tor Relief Valves and Automatic Gas Shutoff Devices lor Hc4 Water Supply Systems, 2t .22
and the code re<]uiremfin($ o1 ASME.
Your localJunsAiAyial authority, wNIe mandating the use of a Temperature-Pressure Reiel Valve complyirtg
uttth AN5 ¿2122 and ASME, may lequite a vaive model differerit Irom the one furnished with the water heater.
CompKanoe with such local requirements must be satislied by the installer or end user of the water heater with
a looaly prescribed Temperature-Pressure Relief Valve installed in the designated opening in the water
heater.

NIPPLE
* If a shod shank (less than 2') temperature-pressure relief vaEve is to be installed
(as shown), a nipple and coupling must be used
* II a long shank (2' or longer} i$ to be installed, do not use the nipple and coupling.
Install Temperature-Pressure protective equipment required by local codes, but not less than a combina­
tion Temperature-Pressure Relief Valve certified as meeting the requiremsms lor Relief Valves and
Automatic Gas Shutctt Devices for Hol-Waler Supply Systems, A\S Z21.22 by a nationatty recognized test­
ing laboratory that maintains periodic irkspedion ol production of listed equipment or malerials. The valve
must be oriented, provided with tubing, or otherwise installed so tiut dischaige car^ exit only within 6 Inches
above, or at any dstance below the stmclurai floor, and cannot contact any live eiectrical part.'
For sate operation of the water heater, the Relief Valve must not be remov^ or plugged.
