Safety Precautions - Kenmore 153.333931 Owner's Manual

Safety Precautions
AWARNING I
Improper installation, adjustment, alteration, service or
maintenance can cause DEATH, SERIOUS BODILY
INJURY, OR PROPERTY DAMAGE. Refer to this manual for
assistance or consult your local Sears Service Center for
further nformat on.
_,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 INJUI_, OR PROPERTY
DAMAGE. If you have any questionsor doubts consult your gas
supplier or local utility.
AWARNING
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS I
(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 causedeath or serious burns to anyone in
the area, as well as property damage.
If installation in such areas is your only option, then the installa-
tion must be accomplished in a way that the pilot flame and
main burner game are elevated from the floor at least Ig inches.
While this may reduce the changesof flammable vapors from a
floor spill being ignited, gasolineand other flammable substances
should never be stored or used in the same room or area con-
taining a gas water heater or other open flame or spark produc-
ing 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 combustion 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 edition of the National Fuel Gas Code, ANSI Z223.1
also referred to as NFPA 54 for specifics provided concernin
! air required.
AWARNING I
A fire can start if combustible materials such as clothing, I
cleaning materials, or flammable liquids are placed against
or next to the water heater.
AWARNING
At the time of manufacture this water heater was provided
with a combination temperature-pressures relief valve certified
by a nationally recognized testing laboratory that maintains
)eriodic inspection of production of listed equipment or mate-
rials, as meeting the requirements for Relief Valves and
Automatic Gas Shutoff Devicesfor Hot Water Supply Systems,
and the latest edition of ANSI Z21.22 and the code require-
ments of ASME If replaced, the valve must meet the require-
, • ,
ments of local codes,but not lessthan a combmaUon tempera-
ture and pressure relief valve cert fled as meet ng the require-
ments for Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supp y Systems, ANS Z2 .22 by a nat onaily recog-
nized 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 satisfied by
the installer or end user of the water heater with a locally pre-
scribed temperature-pressure relief valve installed in the desig-
nated opening in the water heater in place of the factory fur-
nished valve.
For safe operation of the water heater, the relief valve must not
be removed from it's designatedopening or plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designatedfor the relief valve,
Position the valve downward and provide tubing so that any dis.
charge 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 dischargeopening must not be
blocked or reduced in size under any circumstances. Excessive
length, ever 30 feet, or use of more than four elbows can cause
restriction and reduce the dischargecapacity 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 unlessa 6" air gap is provided.To prevent bodilyinjury, haz-
ard to life, or property damage, the relief valve must be allowed
to dischargewater in quantities shouldcircumstancesdemand. If
the discharge 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 couplingsor other restrictions.
• Must not be plugged or blocked.
i • 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 dram.
Must not haveany valve between the relief valve and tank.
