Relief Valve
AWARNING
At the tíme of manufacture this water heater was provided
with a combination temperature-pressures relief valve cer­
tified by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed equip­
ment or materiaJs, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, and the current edition of ANSI Z2I.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 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 * CSA 4.4 fcy a nationally rec­
ognized testing laboratory that maintains periodic inspec­
tion 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 IbsJsq, in,} and a dischai^e capacity
not less than the water heater input rate as shown on the
model rating plate. (Electric heaters - watts divided by
1000 X 3412 equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use
of a temperature-pressure relief valve complying with ANSI
Z21,22 * CSA 4,4 and ASME, may require a valve model dif­
ferent 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 itis designated opening or plumed.
The temperature-pressure relief valve must be installed
directly into the fitting of the water heater designated for
the relief valve. Position the valve downwat^ and provide
tubing so that an^ discharge will exit only within ¿ 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, not connect tubing directly to
dischai^e drain unless a « air gap is provided. To prevent
bodily injury, hazard to life, or property dama:^, 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 m^ 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
restrictions.
* Must not be plui^ed 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,
* M ust terminate at an adequate d rain,
*
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 m^
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.
