Instructions for Installation (cont'd)

Temperature-Pressure Relief Valve

&WARNING	J
At the time of manufacture this water heater was provid-

ecl with a combination temperature-pressuresrelief va ve certified by a nationally recognizedtesting laboratory that maintains periodic inspection of production of listed I equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot

Water Supply Systems, and the latest edition of ANSI ZZ1.22 and the code requirements of ASME. If replaced, the valve must meet the requirementsof local codes,but not less than a combination temperature and pressure relief valve certified as meeting the requirements for

Relief Valves and Automatic Gas Shutoff Devicesfor Hot Water Supply Systems,ANSI Z21.22 by a nationally recog-

nized testing laboratory that maintains periodic inspection of production of listed equipment or materials.

The valve must be marked with a maximum set pressure

not to exceedthe marked hydrostaticworkJng pressureof the water heater (150 Ibs./sq.in.) and a dischargecapacity

not lessthan the 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-pressurerelief valve complyingwith ANSI Z21.22 and ASME, may require a valve model differ- ent from the one furnished with the water heater.

Compliancewith suchlocal requirementsmust be satisfied by the installer or end user of the water heater with a

locally prescribed temperature-pressure relief valve installed in the designated opening 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 pugged.

temperature-pressurerelief valve must be installed :ctly into the fitting of the water heater designated for relief valve. Positionthe valve downward and provide tubing so that any dischargewill 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 treduced in size under any circumstancesExc. essivelength,

No valve or other obstruction isto be placed between the relief valve and the tank. Do not connecttubing directlyto 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 circumstancesdemand, If the dischargepipe is not connected to a drain or other suitable means, the water

AWARNING

7he temperature-pressure relief valve must be manu- ally 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 discharge line, and (2) the water manually dis-

!charged will not cause any bodily injury or property damage because the water may be extremely hot.

I If after manually operating the valve, it fails to corn- pletely reset and continues to release water, immedi-

ately close the cold water inlet to the water heater, follow the draining instructions, and replace the

,temperature-pressure relief valve with a new one.
