Safety Precautions
_,WARNING
A gas water heater cannot operate properly without the
correct amount of air for combustion. Do not install in a
confined area such a closet, unless you provide air as
shown in the "Facts to Consider About the Location" sec-
tion. Never obstruct the How of ventilation air. If you have
any doubts or questions at all, call your gas company.
Failure to provide the proper amount of combustion air
can result in a fire or explosion and can cause DEATH
SERIOUS BODILY INJURY,OR PROPERTY DAMAGE.
_,WARNING
This water heater must not be installed directly on car-
peting. Carpeting must be protected by a metal or wood
panel beneath the appliance extending beyond the full
width and depth of the appliance by at least 3 inches
(76.2mm) in any direction, or if the appliance is installed
Iin an alcove or closet, the entire floor must becovered by
;the panel. Fa ure to heed th s warn ng may result n a
fire hazard.
A,WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
pereture which will satisfy clothes washing, dish washing,
and other sanitizing needs can scald and permanently
injure you upon contact. Some people are more likely to
be permanently injured by hot water than others. These
include the elderly, children, the infirm, or physically/men-
tally handicapped. If anyone usinghot water in your home
fits into one of these groups or if there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must take special precautions. In addi-
tion to usingthe lowest possibletemperature setting that
satires your hot water needs, a means such as a mixing
valve, shouldbe used at the hot water taps used bythese
people or at the water heater. Mixing valves are available
at plumbing supply or hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the
"Temperature Regulation" section in this manual.
A,WARNING
Soot build-up indicates a problem that requires correc-
tion before further use. Turn "OFF" gas to water heater
and leave "OFF" until repairs are made, because failure
to correct the causeof the sooting can result in a Ere or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
&WARNING
VENT DAMPERS - Any vent damper, whether it isoperat-
ed thermally or otherwise must be removed if its use
inhibitsproper drafting ofthe water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80% may
produce a relatively low flue gas temperature. Suchtem-
paratures may not be high enough to properly open ther-
mall), operated vent dampers. This would causespillageof
flue gasesand may causecarbon monoxide poisoning.
Vent dampers must bear evidenceof certification ascom-
splying with the latest edition of American National
taodard ANSI Z21.68 (ANSI Z21.66 & 67, respectively,
cover electrically and mechanically actuated vent
dampers). Before installation of any vent damper, consult
your local Sears Service Center or the gas utility for fur-
ther information.
&WARNING
• The appliance and its individual shutoff valve must be dis-
connected from the gas supply piping system during any
pressure testing of the gas system at test pressures in
excessof ½ pound per square inch(3.SkPa).
• The appliance must be isolated from the gassupply pip-
ing system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping sys-
tem at test pressures equal or less than _/2pound per
square inch(3.SkPa).
_,WARNING
BEFORE LIGHTING [PROPANE (L.R) GAS WATER
HEATERS]: Propane (L.R) gas is heavier than air. Should
there be a leak in the system, the gas will settle near the
ground. Basements, crawl spaces, skirted areas under
mobile homes (even when ventilated), closets and areas
below ground level will serve as pockets for the accumula-
tion of this gas. Before attempting to light or relight the
water heater's pilot or turning on a nearby electrical light
switch, be absolutely sure there is no accumulated gas in
the area. Search for odor of gasby snimngat ground level
in the vicinity of the appliance. If odor is detected, follow
steps indicated at "For Your Safety" on the cover page of
this manual then leave the premises.
A, WARNING
Chemical vapor corrosion of the flue and vent system
may occur if air for combustion contains certain chemical
vapors. Spray can propellants, cleaningsolvents,refrigera.
tor and air conditioner refrigerants, swimming pool
chemicals, calcium and sodium chloride, waxes, bleach,
and process chemicals are typical compounds which are
potentially corrosive.
&,WARNING
Obstructed or deteriorated vent systems may present a
serous heath r skor asphyxat on.
