Kenmore 153.33439, 153.33459 Safety Precautions, Water Heaters Equipped for ONE Type GAS

Safety Precautions

&WARNINGI

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

Center for further nformation.

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 ON THE MODEL RATING PLATE. Failure to usethe correct gascan causeproblemswhich can result in

DEATH, SERIOUS BODILY INJURY, OR PROPERTY

DAMAGE. If you have any questions or doubts consult your gassupplier or 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 fiammablG vapors, may be improperly stored or used in such areas. The gaswater 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 areas of 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.

_,WARNINGI

Afire can start if combustible materials such as clothing,I cleaningmaterials, or flammable liquids are placed against

or next to the water heater.

AWARNING

At the time of manufacture this water heater was provid- ed with a combination temperature-pressures relief valve certified by a nationally 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 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 Devices for 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 pressur_ 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-pressure 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 Ioca_ 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 designatedopemng m the water heater in place of the fa-c_Fu-i_fsll-edvalve.

For safe operation of the water heater, the relief valve must not be removed fr_mmTtJs-_lesignatedopening or

plugged. _ ................ _ ........

The temperature-pressure relief valve must be installed directly into _he-flttlngof the water 4seaterdesignated for

the relief valv_ Positionthe valve downward and provide tubing so that any_lsc-_r-_'wrn_i_ only_vithin 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 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.
