Temperature-Pressure
Relief Valve
AWARNING
At die tíme of manufocture thb ¥rater heater was provided with
a combination temperature-pressures relief valve certified by a
nationally recognized ^ng laboratory that maintains période
inspection of production of listed equipment or materials, as
meeting the requirements for Relief Vidves 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 Viilves and
Automatic Gas Shutoff Devices for Hot >^ter Supply Systems,
ANSI Z2I.22 by a nationally recognized testing laboratory that
maintains periodic inspection of induction 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 tíie 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
a^ ASHE m^ require a valve model different from the one fur­
nished 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 pre­
scribed tempeiatore-pressure relief valve installed in the desig­
nated opening in the water heater in place of the fectory fur­
nished rálve.
For safe operation of the water heater, the relief valve must not
be removed from №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 dis­
charge 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 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 Dischaige 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 plu¿¡ed or blocked.
Must be of material listed for hot water distribution.
Must be installed so as to allow complete drains of both
the temperature-pressure relief valve, and the discharge
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,
3nd (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
^e cold water inlet to the water heater, follow the drain­
ing instructions, and replace the temperature-pressure
relief valve with a new one.
