Safety Precautions
•,WARNING .
I
Improper installation, adjustment, alteration, service
or maintenance can cause DEATH, SERIOUS BODILY I
INJURY, OR PROPERTY DAMAGE. Refer to this manu-
I al for assistance or consult your local Sears Service
L
Center for further nformat on.
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
usathe correct gascan causeproblemswhich can result 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 whichemit flammabk
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
instaflatlonmust 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 vaporsfrom a floor spill being ignited, gasoline
and other flammable substances shouldnever be storedor
used in the same room or area containing a gas water
heater or other openflame 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 J
A fire can start if combustible mate.riaissuch as clothin_
I
deaning materials, or flammable IKimdsare placedagainst
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 Valvesand Automatic Gas Shutoff Devicesfor Hot
Water Supply Systems, .andthe 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-pressure relief valve complying
with ANSI 2121.22and ASME, may require a valve model
different from the one furnishedwith the water heater.
Compliance with such local requirements n_us_ be satis-
fied by the installer or _nd 6sarJofthe Water heater with
a locally prescribed tempe_rat_re-pre_ur¢ relief valve

No valve or other obstru;'tion is to: be placed between
the relief valve and the tank. Do not connect_tubing
directly to discharge drain unless a 6" air gap is provided.
To prevent bodily injury, hazard to life, or property darn-
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 ailow complete drainage of
both the temperature-pressure relief vaive, and the dis-
charge pipe.
Must terminate at an adequate drain.
• Must not have any valve between the relief valve and
tank.
