Safety Precautions
AW,.ARNING . .
Imp,roper installation, adustment, alteratlon, service or I maintenance can cause death, serious bodily injury, or I
property damage. Refer to this manual for assistanceor I 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 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 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 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 accomplished in a way that the pilot flame and main burner flame are elevated from the floor
at least 18 inches. While this may reduce the changesof
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.
_,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 com-
bustion and ventilation air be taken from outside these
areas. Refer to the "Locating The New Water Heater" section of this manual and also the latest edition of the
i National Fuel Gas Code, ANSI Z223.1, also referred to as I NFPA 54 for specificsprovided concerningair required.
_,WARNINGI
AE_ can start if combustible materials such as clothing, I cleaningmaterials, or flammable liquidsare placedagainst
or next to the water heater.
_,WARNING
At the time of manufacture this water heater was provid- ed with a combination temperature-pressuros relief vaive 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 lessthan a combination temperature and
pressure relief valve certified as meeting the require- ments for Relief Valves and Automatic Gas Shutoff
Devices for Hot Water Supply Systems,ANSI Z21.22 by a nationally recognized 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-pressure relief valve complying
with ANSI Z21.22 and ASME, may require a valve model different from the one furnishedwith 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 designatedopening 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. Positionthe valve downward and pro- vide 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 reduced in size under any circumstances. Excessivelength, 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 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 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 dischargepipe.
Must terminate at an adequate drain.
Must not have any valve between the relief valve and tank.
