Safety Precautions
AWARNING I
Improper installation, adjustment, alteration, service or I
maintenance can cause DEATH, SERIOUS BODILY I
INJURY, OR PROPERTY DAMAGE. Refer to this manu-
al for assistance or consult your local Sears Service
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
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 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 gas water 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 chances of
flammable vapors from a floor spill being ignited, gasoline
and other flammable substancesshould 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 serf-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 specificsprovided concerning air required.
AWARNING
A fire can start if combustible materialssuchas clothing
cleaningmaterials,or flammableliquids are placedagainst
or nextto thewater heater.
&WARNING
At the time of manufacture this water heater was pro-
vided with a combination temperature-pressures relief
valve certified by a nationally recognized testing labora-
tory that maintains periodic inspection of production of
listed equipment or materials, as meeting the require-
ments 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 require-
ments of local codes, but not less than a combination
temperature and pressure relief valve certified as meet-
ing the requirements for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems,
ANSI Z21.22 by a nationally recognized testing laborato-
ry 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.lsq. 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 BTUIHr. rate.)
Your local jurisdictional authority, while mandating the
use of a tempereture-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 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
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 carl
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.
