Safety Precautions
I AWARNING 1
Improper installatio_alteration, service or I
maintenance can cause death, serious bodily injury, or[
property damage. Refer to this manual for assistanceor
consult your local Sears Service Center for furtherl
information. ]
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 _ result in
DEATH, SERIOUS BODILY INJURY, OR PR.OPERTY
DAMAGE. If you have any questions or doubts consult
your gassupplier 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 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 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 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 teat 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 specificsprovidedconcerningair required.
AWARNING
A fire can start if combustible materials such as clothing, I
cleaningmaterials, or flammable liquidsare 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 inspectionof 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 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 local requirements must be satis-
fied by the installer or end user of the water heater with
a locally prescribed temperature-pressure relief valve
installedin the designatedopening in the water heater in
place of the factory furnished valve.
For safe operation of the water heater, the relief valve
must not be removect from'lt's-designatec_ opening or
plugged.
The tempera_p-_ssut'-e-_l|ef-va'lve'rnust be installed
directly into the fittins-of-th_.watar heater designated
for the relief valve. Positionthe valve downward and pro-
vide tubing so that any disc_wilt exit only within'6
inches above, or at an_(distance below the structural i
floor. Be cert_'thi_'h_'_6-n_-_t'Ts'i_ad_ With any live
electrical part.The discharge opening must not be
blocked or reduced in size under any circumstances.
Excessivelengthi over._30feet,-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
dischargepipe.
• Must terminate at an adequate drain.
• Must not have any valve between the relief valve and
tank.
