Safety Precautions
_,WARNING
A gaswater beater 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 "Facts to Consider About the Location" sec-
tion. Never obstruct the flow 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.
AWARNING
This water heater must not be installed directly on car-
peUng.Carpeting must be protected bya 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 isinstalled
in analcove or closet,the entire floor must becoveredb
the panel. Failure to heed this warning may result in i
fire hazard.
A,WARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tam-
peraturo whichwill satisfyclotheswashing;dishwashing,
and other sanitizing needs can scald and permanently
injure you upon contact. Some people are more likelyto
be permanently injured by hot water than others. These
includethe eldedy, children,the infirm, or physically/men-
tally handicapped.If anyoneusinghot water in yourhome
fits into one of these groupsor if there is a local code or
state law requiring a certain temperature water at the hot
water tap, then you must take specialprecautions.In addi-
tion to usingthe lowest possibletemperature setting that
satisfiesyour hot water needs,a means suchas a mixing
valve, shouldbe usedat the hot water taps usedbythese
people or at the water heater. Mixingvalvesare available
at plumbing supplyor 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.
_,WARNING
Soot build-up indicates a problem that requires correc-
tion beforefurther use.Turn "OFF" gasto water heater
and leave "OFF" until repairs are made, becausefailure
to correct the causeof the sootingcan 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 draftingof the water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiencyin excessof 80% may
produce a relatively low flue gastemperature. Suchtem-
peratures may not be high enoughto properly openther-
mally operated vent dampers.Thiswouldcausespillageof
fluegasesand may causecarbonmonoxide poisoning.
Vent dampers must bear evidenceof certificationas com-
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 anyvent damper, consult
your localSears Service Center or the gasutility for fur-
ther information.
_,WARNING
•The appliance and its individualshutoffvalvemustbe dis-
connectedfrom the gassupplypipingsystemduring any
pressure testing of the gassystem at test pressuresin
excessof ½poundper squareinch(3.5kPa).
•The appliance must be isolatedfrom the gassupplypip-
ing system by closingits individualmanual shutoffvalve
during any pressuretestingof the gassupplypipingsys-
tem at test pressuresequal or lessthan Y_pound per
squareinch(3.5kPa).
AWARNING
BEFORE LIGHTING [PROPANE (L.R) 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 groundlevelwill serve as pocketsfor the accumula-
tion of this gas.Before attempting to light or relight the
water heater's pilot or turning on a nearbyelectrical light
switch, be absolutelysure there is no accumulatedgasin
the ares Search for odor of gasbysniffingat groundlevel
in the vicinity of the appliance. If odor is detected, follow
stepsindicatedat "For Your Safety" on the cover page of
this manualthen leavethe premises.
_,WARNING
Chemical vapor corrosion of the flue and vent system
may occur if air for combustioncontainscertain chemical
vapors.Spraycanpropellants,cleaningsolvents,refrigera-
tor and air conditioner refrigerants, swimming pool
chemicals, calcium and sodium chloride, waxes, bleach,
and processchemicalsare typical compoundswhich are
potentially corrosive.
A, WARNING
i
Obstructed or deteriorated vent systemsmay present a
serioushealthrisk or asphyxiation.
