Safety Precautions

• _W,.ARNING .

Impro.per installation, adjustment , alteration, service or maintenance can cause DEATH, SERIOUS BODILY

INJURY, OR PROPERTY DAMAGE. Refer to this manu- I al for assistance or consult your local Sears Service

[ Center for further information.

AWARNING

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 QN THE MODEL RATING PLATE. Failure to usethe correct gascan causeproblem'swhich canresult in

DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your gassupplieror localutility.

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 pilot light 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 accomplishedin a way that the pilot flame and main burner flame are elevated from the floor

at least 18 inches. While this may reduce the chancesof flammable vapors from a floor spill being ignited, gasoline and other flammable substancesshouldnever be stored or used in the same room or area containing a gas water heater or other open flame or spark producingappliance. NOTE: Flammable vapors may be drawn by air currents from other areasof the structure to the appliance.

AWARNING

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 com-

bustion and ventilation air be taken from outside these areas. Refer to the "Facts to Consider About the

Location" section of this manual and also the latest edi- tion of the National Fuel Gas Code, ANSI Z223.1, also

referred to as NFPA 54 for specificsprovided concerning air required.

_.WARNING	]
A fire can start if co_Hals	such as clothing,

cleaningmaterials, or flammable liquidsare placed against

or next to the water heater. /

_,WARNING

At the time of manufacture this water heater was provid- ed with a combination temperature-pressures relief valve

certified by a nation.ally, recognized testing laboratory that maintains penodlc inspection of production of listed

equipment or materials, as meeting the requirements for

Relief Valves and Automatic Gas Shutoff Devicesfor 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 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 rec- ognized 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 exceed the marked hydrostatic working pressure of the water heater (150 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 3415 equal BTU/Hr. rate.)

Your local jurisdictional authority, while mandating the use of a temperature-prossure relief valve complying

with ANSI Z21.22 and ASME, may require a valve model different 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 b_ _OV---e'a'Trom_-'T_-'ed_g_aT_d_openingor plugged...........................

The temperature-pressure relief valve must be installed directly into_he_fieein_f_the-weterheater designatedfor the relief valve. Positionthe valve downward and provide tubing so that any dischal_e-WHT_it only within 6 inches above, or at any_dis.tancebe!ow 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,-oruse 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 dischargedrain unlessa 6 air gap is provided.

To prevent bodily injury, hazard to life, or property dam- age, the relief valve must be allowed to dischargewater in quantities should circumstances demand• If the dis- charge pipe is not connected to a drain or other suitable means, the water flow may causeproperty 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 pluggedor 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.
