Safety Precautions
I _,WARNING
Improper instailatio_lteratlon, 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 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
usethe correct gascan cause problemswhich can result in
DEATH, SERIOUS BODILY INJURY, OR PROPERTY
DAMAGE. If you have any questions or doubts consult
your gassupplier or localutility.
_,WARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQ-
UIDS (VAPORS) ARE LIKELY TO BE PRESENT OR
I STORED (GARAGES, STORAGE, AND UTILITY AREAS,
ETC): Flammable liquids (such as gasoline, solvents,
I propane (LP) or butane, etc.), all ofwhich 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 vaporsfrom 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 sparkproducing 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 astablishments, 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 specifics provided concerning
air required.

A, WARNING
At the time of manufacture this water heater was provid-
led 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 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 beaters -
watts divided by 1000x 3415 equal BTUIHr. rate.)

floor. Be certain that _fo €0ntact_is ffiEde._with any live
electrical part. The discharge opening must n'bt 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 discharge drain unlessa 6" air gap isprovided.
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 plugged or blocked.
• Must beof 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 ternljnate at an adequate drain.
• Must not have any valve between the relief valve and
tank.
