Safety Precautions
&WARNING
I
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 nformation.
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 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 which emit fiammablG
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 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 vapors from a floor spill being ignited, gasoline
and other flammable substances shouldnever 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 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 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
I
A fire can start if combustible materials such as clothing,I
cleaningmaterials, or flammable liquids are placed against
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 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 requirements for
Relief Valves and Automatic Gas Shutoff Devices for 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 pressur_
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 furnished with the water heater.
Compliance with.such Ioca_ 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 designatedopemng m the water heater in
place of the fa-c_
Fu-i_ fsll-edvalve.
For safe operation of the water heater, the relief valve
must not be removed fr_mm TtJs-_lesignated opening or
plugged.
_ ................
_
........
The temperature-pressure relief valve must be installed
directly into _he-flttlng of the water 4seaterdesignated for
the relief valv_ Positionthe valve downward and provide
tubing so that any_lsc-_r-_'wrn_i_
only_vithin 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. 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 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 dischargewater
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 dis-
charge pipe.
• Must terminate at an adequate drain.
• Must not have any valve between the relief valve and
tank.
