Temperature-Pressurerelief Valve - Kenmore 153.33525 Owner's Manual

Temperature-PressureRelief Valve
WARNING
At the time of manufacture this water heater was provided
with a combination temperature-pressures relief valve certi-
fied by a nationally recognized testing laboratory that main-
tains 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 eoidon of ANSI Z21.22 and the code
requtrements of ASME. If replaced, the valve must meet the
requirements of local codes, but not lessthan 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 recognized testing laborato_ 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 (150 Ibs./sq. in.) and a discharge cai_city not
lessthan the water heater input rate as shown on the model
rating plate. (Electric heaters - watts divided by 1000 x 3415
equa| BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use
of a temperature-pressure relief valve complyingwith ANSI
Z21.22 and ASME, may require a valve moc'lel d_erent 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
€leslgnated opening in the water heater in place of the facto-
ry 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 fittin_of the water heater designated for the
relief valve. Position t_e valve downward and provide tubing
sothat 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. Excessivelength, over 15 feet_ or use of more
than two 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 oroperty damage, the relief
valve must be allowed to discharge water in quantities
should circumstances demand. If the discharge pnpe is not
connected to a drain or other suitable means, t-hewater flow
may cause property damage.
The Discharlze Pipe:
.
_
'--Must not Ee smaller in size than the outlet pipe size of the
valve, or have any reducing couplingsor other restriction.
---Must not be
plumed
or blocked.
_ust be of mate_]'al listed for hot water distribution.
_ust be installed so as to allow complete drainage of both
the temperature-pressure relief valve, and the discharge

WARNING
The temperature-pressure relief valve must be manual-
ly operated at least once a year. Caution should be
taken to ensure that (1) no one is in front of or around
the outlet of the temperature-pressure relief valve dis-
charge 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 com-
pletely reset and continues to release water, immedi-
ately closethe cold water inlet to the water heater, fol-
low the draining instructions, and replace the tempera-
ture-pressure relief valve with a new one.
