Temperature-Pressure
Relief Valve
AWARNING
At die time of manufacture this water heater was provid­
ed with a combination temperature-pressures reiief vaive
ceKified by a nationaiiy 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
Z2I.22 and the code requirements of ASME. If replaced,
the vaWe 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 Z21.22 by a nationally recog­
nized testing lalraratory that maintains periodic inspection
of production of listed equipment or materials.
The valve must be mari^ with a maximum set pressure
not to exceed the marked hydrostatic working pressure of
the water heater (ISO lbs./sq. in.) and a dischar^ capacity
not less th|ui 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 valve model differ­
ent from the one furnished with the water heater.
Compliance with such local requirements must be satis­
fied by the inst^ler 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 fiictory 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 will 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
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 die discharge capacity of the valve.
No valve or other obstruction is to be placed between the
reiief 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 he 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 vrater 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 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 valve with a new one.
