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 i 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
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a tern- 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 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.
_,WARNING
Soot
explosion causing DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.
AWARNING
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 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 gas by sniffing at ground level in the vicinity of the appliance. If odor is detected, follow steps indicated at "For Your Safety" on the cover page of :his manual then leave the premises.
AWARNING
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
The power vent water heater requires its own (separate) venting system. It cannot be connected to an existing vent pipe or chimney. It must be terminated horizontally to the outdoors. Failure to properly install the venting system can result in asphyxiation, a fire or explosion and can cause
DEATH, SERIOUS BODILY INJUR_, OR PROPERTY DAM- AGE.
&WARNING
No vent damper installation is compatible with this power vented water heater design. No vent damper, whether it is operated thermally or otherwise is to be installed on this power vented w=ter heater. Alteration of any part of the fac-
,
_,WARNING
,The appliance and its individualshutoff valve must be dis- connected from the gassupply piping system during any pressure testing of the gas system at test pressures in excessof I/2 poundper squareinch(3.5kPa).
•The appliance must be isolated from the gas supplypip- ing system by closingits individual manual shutoff valve during any pressure testing of the gas supplypiping sys- tem at test pressures equal or lessthan I/2 pound per squareinch (3.5kPa).
AWARNING
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.
AWARNING
Obstructed or deteriorated vent systems may present a serious health risk or asphyxiation.
