Safety Precautions
_,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
shown in 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.
_WARNING
This water heater must not be installed directly on car-
Feting. Cerpe_ag 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 iftbe appliance is installed
in an alcove or coset, the entire floor must be coveredby
the panel. Failure to heed this warning may result in a
Ere hazard.
AWARNING
AWARNING
HOTTER WATER CAN SCALD: Water heaters are
intended to produce hot water. Water heated to a tern-
perature which willsa_ clotheswashing, disk washing,
and other sanitizing needs can scald and permanently
injure you upon €ontac_ Some people ace more likely to
be permanently injured by hot water than other_ These
include the elderly,children, the infiPm,or physicailyimen-
tally handicapped. If anyone usinghot water in your home
fits into one of these groups or if there Is a local code or
state Ilw requiringa certain temperature water at the hot
water tap, then you must take specialprecautions,In addi-
tion to usingthe lowest possible temperature setting that i
satisfiesyour hot water needs, a means such as a mixing I
valve, shouldbe used at the hot water taps used by these
I
people or at the water heater. Mixing valvesare available
at plumbing supply or hardware stores. Follow manufac-
turers instructions for installation of the valves. Before
changing the fa_)ry setting on the thermostat, read the
'_l'emperature Regulation" sectionin 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 cause of the sooting can result in s fire or
Iexplosion causing DEATH, SERIOUS BODILY INJURY,
OR PROPERTY DAMAGE.
VENT DAMPERS - Any vent damper, whether it isoperat-
ed thermally or otherwise must be removed if Its use
inhibits proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water
heaters having thermal efficiency in excess of 80% may
*roduce a relatively low flue gastemperature. Such tem-
peratures may not be high enough to properly open ther-
mally operated vent dampers. This would causespillageof
flue gasesand may cause carbon monoxide poisoning.
Vent dampers must bear evidence of certification as 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 installation of any vent damper, consult
your local Sears Service Center or the gas utility for fur-
ther nformat on.
AWARNING
•The appliance and its Individual shutoff valve must be dis.
connected from the gallsupply piping systemduring any
pressure testing of the gas system at test pressures In
excessof '/2pound per square inch(3.$kPa).
•The appliancemust be isolatedfrom the gassupplypip-
ing system by closing its individual manual shutoffvalve
during any pressuretesting of the gas supplypiping sys-
tem at test pressures equal or less than '/2pound per
square Inch (3.SkPa).
_,WARNING
BEFORE LIGHTING [PROPANE (L.P.) GAS WATER
HEATERS): Propane (L.R) gas is 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 ground levelwill serve as pockets fur 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 aceL Search for odor of gas by sniffingat 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 manualthen leavethe premises.
AWARNING
Chemical vapor corrosion of the flue and vent system
may occur if air fur combustion contains certain chemical
vapors. Spray can propellants, cleaning solvents,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.
