Installation Instructions

Temperature-Pressure

Relief Valve

AWARNING

At the time of manufacture this water heater was provided with a combinationtemperature-pressures relief valve cer- tified by a nationally recognized testing laboratory that

maintains periodic inspectionof productionof listed equip- ment or materials, as meeting the requirements for Relief

Valvesand Automatic Gas Shutoff Devicesfor Hot Water SupplySystems,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 less than a combination temperature and pressure relief valve certified as meeting the requirements for ReliefValvesand

Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized testing laboratory that maintains periodic inspectionof production of listed equipment or materials.

The valve must be marked with a maximum set pressure not to exceed the marked hydrostaticworking pressureof the water heater (150 Ibs./sq.in.) and a dischargecapacity not lessthan the water heater input rate as shownon the

model rating plate. (Electric heaters - watts divided by 1000x 3415 equal BTU/Hr. rate.)

Your localjurisdictional authority, while mandatingthe use

of a temperature-pressure relief valve complying with ANSI Z21.22 and ASME, may require a valve model differ- ent from the one furnishedwith the water heater.

Compliance with such local requirements must be satisfied _)ythe installer or end user of the water heater with a locally prescribed temperature-pressure relief valve installedin the designatedopening in the water heater in place of the factory furnishedvalve.

For safe operation of the water heater, the relief valve must not be removed from it'sdesignated opening or plugged.

The temperature-pressure relief valve must be installed directly into the fitting of the water heater designatedfor

the relief valve. Positionthe valve downward and provide tubing so that any dischargewill exit only within 6 inches above,or at any distancebelow the structural floor. Be cer- tein that no contact is made with any llve electrical part. The dischargeopening must not be blocked or reduced in size under any circumstances. Excessivelength, over 30 feet, or use of more than four elbowscan causerestriction and reduce the dischargecapacityof the valve.

No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to dischargedrain unlessa 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

(cont'd)

_,WARNING

The temperature-pressure relief valve must be manually operated at least once a year. Caution shouldbe 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 dischargedwill not causeany bodily injury or property damage becausethe water may 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 valvewith a new one.

The DischargePipe:

Must not be smaller in size than the outlet pipe size of

the valve, or have any reducing couplings or other restriction.

Must not be pluggedor blocked.

Must be of material listedfor hot water distribution.

Must be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the dis- charge pipe.

Must terminate at an adequatedrain.

Must not have any valve between the relief valve and tank.
