Safety Precautions

AWARNINGJ

Improper installation, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manu- J al for assistance or consult your local Sears Service Center for further information.

_;LWARNING

WATER HEATERS EQUIPPED FOR ONE TYPE GAS ONLY: This water heater is equipped for one type gas only. Check the model rating plate near the gas control

valve for the correct gas. DO NOT USE THIS WATER HEATER WITH ANY GAS OTHER THAN THE ONE

SHOWN ON THE MODEL RATING PLATE. Failure to use the correct gas can cause problems which can result in

DEATH, SERIOUS BODILY INJURY, OR PROPERTY

DAMAGE. If you have any questions or doubts consult your gas supplier or local utility.

AWARNING

INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ- UIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE, AND UTILITY AREAS, ETC): Flammable liquids (such as gasoline, solvents, propane (LP) or butane, etc.), all of which emit flammable vapors, may be improperly stored or used in such areas. The gas water heater ignitor or main burner can ignite such vapors. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage.

If installation in such areas is your only option, then the

installation must be accomplished in a way that the ignitor and main burner flame are elevated from the floor at least

18 inches. While this may reduce the chances of

flammable vapors from a floor spill being ignited, gasoline and other flammable substances should never be stored or

used in the same room or area containing a gas water heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.

_WARNING

If this water heater will be used in beauty shops, barber shops, cleaning establishments, or self-service laundries with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that combus- tion and ventilation air be taken from outside these areas. Refer to the "Facts to Consider About the Location" sec- tion of this manual and also the current edition of the National Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for specifics provided concerning air required.

AWARNING

Afire can start if combustible materials such as clothing, cleaningmaterials, or flammable liquidsare placedagainst or next to the water heater.

AWARNING

At the time of manufacture this water heater was provided

with a combination temperature-pressure relief valve certi- fied by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equip- ment or materials, as meeting the requirements for Relief

Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, and the current edition of ANSI Z21.22, CSA 4.4 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 Relief

Valves and Automatic Gas Shutoff Devices for Hot Water

Supply Systems ANSI Z21.22 • CSA 4.4 by a nationally rec- ognized testing laboratory that maintains periodic inspec- tion of production of listed equipment or materials.

The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (I 50 Ibs./sq. in.) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters, watts divided by 1000 x 3412 equal BTU/Hr. rate.)

Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI Z21.22, CSA 4.4 and ASME, may require a valve model dif- ferent from the one furnished with the water heater.

Compliance with such local requirements must be satis- fied 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 furnished valve.

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 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 cer- tain 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 discharge capacity 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 unless a 6" air gap is provided.

To prevent bodily injury, hazard to life, or property dam- age, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the dis- charge 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 restrictions.

_Must not be 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 discharge pipe.

--Mustterminate at an adequate drain.

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