Safety Precautions
_t,WARNING
A gaswater 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
shownin the "Locating The New Water Heater" section.
Never obstruct the flow of ventilation air. If you haveany
doubts or questionsat all, call your gascompany. Failure
to providethe proper amount of combustionair canresult
in a fire or explosion and can cause DEATH, SERIOUS
BODILY INJURY,OR PROPERTY DAMAGE.
AWARNING
This water heater must not be installed directly on car-
peting. Carpeting must be protected bya metal or wood
_anel 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 isinstalled
in an alcoveor closet, the entire floor must be coveredby
the panel. Failure to heed this warning may result in a
fire hazard.
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tem-
perature which will satisfyclotheswashing,dishwashing,
and other sanitizing needs can scald and perm..a.nently
injure you upon contact. Some people are more likelyto
be permanently injured by hot water than others. These
includethe elderly,children,the infirm, or physically/men-
tally handicapped.If anyoneusinghot water in your home
fits into one of these groupsor if there is a local code or
state lawrequiring a certain temperature water at the hot
water tap, then you must take specialprecautions.In addi-
tion to usingthe lowest possibletemperature set_ng that
satisfies your hot water needs,a means suchas a mixing
valve, shouldbe usedat the hot water taps usedbythese
people or at the water heater. Mixing valvesare available
at plumbingsupply or hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changingthe factory setting on the thermostat, read the
"Temperature Regulation"sectionin this manual.
AWARNING
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 cause of the sooting can result in a fire or
explosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
AWARNING
VENT DAMPERS - Any vent damper,whether it isoperat-
ed thermally or otherwise must be removed if its use
inhibitsproper draftingofthe water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80% may
produce a relatively low flue gastemperature. Suchtem-
peratures may not be high enoughto properly open ther-
maily operated vent dampers.This wouldcausespillageof
flue gasesand may causecarbon monoxidepoisoning.
Vent dampers must bear evidenceof certification ascom-
plying with the latest edition of American National
Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively,
cover electrically and mechanically actuated vent
dampers). Before installationof any vent damper, consult
your local Sears Service Center or the gas utility for fur-
ther information.
&WARNING
• The appliance and its individualshutoffvalvemust bedis-
connected from the gassupplypiping systemduring any
pressure testing of the gassystem at test pressuresin
excessof I/2 poundper squareinch(3.5kPa).
• The appliance must be isolatedfrom the gassupplypip-
ing system by closingits individualmanual shutoffvalve
during any pressuretesting of the gassupplypiping sys-
tem at test pressuresequal or lessthan I/2 pound per
squareinch(3.SkPa).
AWARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS]: Propane (L.R) gasis heavier than air. Should
there be a leak in the system,the gaswill settle near the
ground. Basements, crawl spaces, skirted areas under
mobile homes (even when ventilated), closets and areas
below groundlevel will serveas pocketsfor 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 surethere is no accumulated gasin
the areL Searchfor odor ofgasbysniffingat ground level
in the vicinity of the appliance. If odor isdetected, follow
stepsindicatedat "For Your Safety" on the cover page of
this manualthen leavethe premises.
A,WARNING
Chemical vapor corrosion of the flue and vent system
may occur if air for combustion containscertain chemical
vapors.Spray canpropellants,cleaningsolvents,refHgera.
tot and air conditioner refrigerants, swimming pool
chemicals, calcium and sodium chloride, waxes, bleach,
and processchemicals are typical compounds which are
potentially corrosive.
_,WARNING
Obstructed or deteriorated vent systems may present a
serous health riskor asphyxation.
