Installation Instructions (cont'd)
Temperature-Pressure
Relief Valve
_,WARNING
At the time of manufacture this water heater was provid-
ed with a combination temperature-pressures relief valve
certified by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed
equipment 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 ASHE. 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 SupplySystems,ANSI Z21.22 bya nationallyrecog-
nized testing laboratory 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 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
1000 x 3415 equal BTU/Hr. rate.)
Your localjurisdictionalauthority, 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 such local requirements must be satis-
fied 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
daceof 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. Position the valve downward and provide
tubing so that any dischargewill exit only within 6 inches
above, or at any distance below the structural floor. Be
certain that no contact is made with any live electrical
)art. The discharge opening must not be blocked or
reduced in size under any circumstances.Excessivelength,
over 30 feet, or use of more than four elbows can cause
restriction and reduce the dischargecapacityof the valve.
No valve or other obstruction is to be placedbetween the
relief valve and the tank. Do not connecttubingdirectly 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
shouldcircumstancesdemand. 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-
charge pipe.
Must terminate at an adequate drain.
Must not haveanyvalvebetweenthe relief valveand tank.
• , WARNING
The temperature-pressure relief valve must be manually
operated at least once a year. Caution shouldbe 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 causeany
bodily injury or property damage becausethe water may
be extremely hot.
If after manually operating the valve, it fails to complete-
ly reset and continues to release water, immediately,
close the cold water inlet to the water heater, follow the
draining instructions, and replace the temperature-pres-
sure relief valvewith a new one.
