Installation Instructions (cont'd)
Temperature-Pressure Relief 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 inspectionof productionof listed equipment or
materials, as meeting the requirements for Relief Valvesand
Automatic Gas Shutoff Devices for Hot Water Supply
Systems, and the latest edition of ANSI Z21.22 and the code
requirements 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 Devicesfor Hot Water SupplySystems, ANSI Z21.22
by a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or
materials.
The valve must be marked with a maximum set pressurenot
to exceed the marked hydrostatic working pressure of _le
water heater (150 Ibs./sq. in.) and a discharge capacity 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 ASHE, may require a valve model different from
the one furnishedwith 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
designatedopening in the water heater in place oftbe facto-
ry furnishedvalve.
For safe operation of the water heater, the relief valve must
not be removed from it's designatedopening 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 inchesabove, 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 dis-
chargecapacity 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 unlessa 6" air gap is provided. To prevent
bodily injury, hazard to life, or property damage, the relief
valve must be allowed to dischargewater in quantities should
circumstancesdemand. If the discharge pipe is not connect-
ed 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 oftbe
valve, or haveany reducing couplingsor other restrictions.
Must not be pluggedor blocked.
Must be of material listed for hot water distribution.
Must be installed so as to allow complete drainage of beth
the temperature-pressure relief valve, and the discharge :
pipe.
Must terminate at an adequate drain.
Must not haveany valve between the relief valve and tank.
AWARNING
The temperature-preesure relief valve must be manually
operated at least once a year. Caution shoukl be taken to
emure that (I) no one ls in front of ov around the outlet of
the temperature-pressure rer_f valve dischargeline, and (2)
the water manually discharged will not cause any bodily
injury or property damage because the water may be
extremaly hot
ff after manually operating the valve, it fails to completely
reset and continnesto release water, immediately dose the
cold water inlet to the water heater, follow the draining
instructions, and replace the temperature-pressuro relief
valvewith a new one.
