Safety Precautions
^WARNING
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 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
DAMAGE. If you have any questions or doubts consult
your gas supplier or local utili^.
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 gas water heater ignitor 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 ignitor
and main burner flame are elevated from the floor at least
18 inches. While this may reduce the chances of
flammable vapors from a floor spill being ignited, gasoline
and other flammable substances should never be stored or
used in the same room or area containing a gas water
heater or other open flame or spark producing appliance.
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 combus­
tion and ventilation air be taken from outside these areas.
Refer to the "Facts to Consider About the Location’’ sec­
tion of this manual and also the current edition of the
National Fuel Gas Code, ANSI Z223.1, also referred to as
NFPA 54 for specifics provided concerning air required.
_________________AWARNING______________________ ^
A fire can start if combustible materials such as clothing,
cleaning materials, or flammable liquids ^e placed ag^nst
or next to the water heater.
AWARNING
At the time of manufactiJre this water heater was provided
with a combination temperature-pressure relief valve certi­
fied by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed equip­
ment or materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, and the current edition of ANSI Z21.22 •
CSA 4.4 and the code requirements of AS ME. 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 • CSA 4.4 by a nationally rec­
ognized testing laboratory that maintains periodic inspec­
tion 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 (i 50 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 34 i 2 equal BTU/Hr. rate.)
Your local jurisdictional authority, while mandating the use of
a temperature-pressure relief valve complying with ANSI
Z2i .22 • CSA 4.4 and ASME, may require a valve model dif­
ferent 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 relief valve must
not be removed from it’s designated opening or plugged.
The temperature-pressure relief valve must be installed
directly into the fitting of the water heater designated for
the relief valve. Position the valve downward and provide
tubing so that any discharge will exit only within 6 inches
above, or at any distance below the structural floor. Be cer­
tain 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 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
both the temperature-pressure relief valve, and the
discharge pipe.
—Must terminate at an adequate drain.
—Must not have any valve between the relief valve and
tank.
