Safety Precautions

AWARNING

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 "Locating The New Water Heater" section. 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- 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 in an alcove or closet, the entire floor must be covered by

the panel. Failure to heed this warning may result in a fire hazard.

_WARNING

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a tem- perature 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 using hot 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 using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these oeople or at the water heater. Mixing valves are available

:plumbing supply or hardware stores. Follow manuFac-

.urers instructions for installation of the valves. Before

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.

&WARNING

VENT DAMPERS - Any vent damper, whether it is operat- 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 produce a relatively low flue gas temperature. Such tem-

peratures may not be high enough to properly open ther- mally operated vent dampers. This would cause spillage of

flue gases and 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 information.

AWARNING

•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 excess of I/2 pound per square inch (3.SEPa).

•The appliance must be isolated from the gas supply 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 I/2 pound per square inch (3.5kPa),

_WARNING

BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]: Propane (LR) 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 rellght 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 gas by sniffing at ground level

......the vicinity of the appliance. If odor is detected, follow

_eps ndicated at "For Your Safety" on the cover page of this manual then leave the premises.

_,WARNING

Chemical vapor corrosion of the flue and vent system may occur if air for 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.

Obstructed or deteriorated vent systems may present a

AWARNINGt serious health risk or asphyxiation.
