Installation Instructions (cont’d)

Temperature-Pressure

Relief Valve

AWARNING

At die time of manufacture this water heater was provid

ed with a combination temperature-pressures reiief vaive

ceKified by a nationaiiy recognized testing laboratory that

maintains periodic inspection of production of listed

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

Z2I.22 and the code requirements of ASME. If replaced,

the vaWe 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 Valves and Automatic Gas Shutoff Devices for Hot

Water Supply Systems, ANSI Z21.22 by a nationally recog

nized testing lalraratory that maintains periodic inspection

of production of listed equipment or materials.

The valve must be mari^ with a maximum set pressure

not to exceed the marked hydrostatic working pressure of

the water heater (ISO lbs./sq. in.) and a dischar^ capacity

not less th|ui 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-pressure relief valve complying with

ANSI Z2I.22 and ASME, may require a valve model differ

ent from the one furnished with the water heater.

Compliance with such local requirements must be satis

fied by the inst^ler 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 fiictory furnished valve.

For safe operation of the water heater, the relief valve

must not be removed from it'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 discharge 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 die discharge capacity of the valve.

No valve or other obstruction is to be placed between the

reiief 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 Discharge Pipe:

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

the valve, or have any reducing couplings or other

restriction.

• Must not he plugged or blocked.

* Must be of material listed for 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 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,

and (2) the vrater 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 complete

ly reset and continues to release water, immediately,

close the cold water inlet to the water heater, follow the

draining instructions, and replace the temperature-pres

sure relief valve with a new one.
