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'sdesignatedopening 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.Excessivelength, 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

extremalyhot

ffafter 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.
