Safety Precautions
&`WARNIN__G
Improper installation, adjustment, alteration, service or maintenance can cause death, serious bodily injury, or property damage. Refer to this manual for assistance or consult your local Sears Service Center for further
I information.
_,WARNING
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 ;)AMAGE. If you have any questions or doubts consult four gas supplier or local utility.
&`WARNING
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 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. qOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.
&`WARNING
f 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
National Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for specifics provided concerning air required.
&`WARNING
A fire can start if combustible materials such as clothing, I cleaning materials, or flammable liquids are 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 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 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 ess 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 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 refief valve must not be removed from it'sdesignated opening or plugged.
The temperature-pressure relief valve must be i_t_lled directly into the fitting of the water heater _ignated for the relief valve. Position tee valve nuw,w_:J_and pro. vide tubing so that any discharg_ will exit only _vithin I

No valve or other obstruction is to be placed_between
the relief valve and the tank::l_-m_mne'_t 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
Must terminate at an adequate drain.
Must not have any valve between the relief valve and bothdischargethe temperature-pressurepipe.reliefvalve, and the tank.
