Water heater corrosion and component f ail ure can be cau se d by the heating and
breakdown of airborne chemical vapors. Examples of some typical compounds that are
potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride,
waxes and process chemicals. These materials are corrosive at very low concentration
levels with little or no odor to reveal their presence
. NOTE: DAMAGE TO THE
WATER HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS
NOT COVERED BY THE WARRANTY. DO NOT OPERATE THE WATER
HEATER IF EXPOSURE HAS OR WILL OCCUR. DO NOT STORE ANY
POTENTIALLY CORROSIVE COMPOUNDS IN THE VICINITY OF THE
WATER HEATER.
NOT CERTAIN OF THE FOLLOWING:
• Liquefied petroleum gases/propane gas and natural gas have an
odorant added by the gas supplier that aids in detection of the gas.
• Most people recognize this odor as a “sulfur” or “rotten egg” smell.
• Other conditions, such as “odorant fade” can cause the odorant to
diminish in intensity, or “fade”, and not be as readily detectable.
• If you have a diminished sense of smell or are in any way unsure of
the presence of gas, immediately contact your gas supplier from a
neighbor’s telephone.
• Gas detectors are available. Contact your gas supplier or plumbing

Proper venting practices must be considered when selecting a locat ion for this
water heater. For exact venting specifications, please consult the Venting
section, located on page 9, of these Installation and Operating Instructions.
This water heater must be located in an area where leakage of the tank, water
line connections, or the combination temperature and pressure relief valve will
not result in damage to the area adjacent to the water heater or to lower floors
of the structure. When such locations cannot be avoided, a suitable drain pan
must be installed under the water heater. The drain pan must have a minimum
length and width of at least 4 in. (10.2 cm) greater than the diameter
of the water heater and must not restrict proper combustion air flow to the
water heater. The drain pan, as described above, can be purchased from your
plumbing professional. The drain pan must be piped to an adequate drain.
The piping must be at least 3/4 inch (1.9 cm) in diameter and pitched for
proper drainage.
It is recommended that a minimum clearance of four (4) inches (10.2 cm) be
provided on the side of the water heater for servicing and maintenance of the
combination temperature and pressure relief valve.
To comply with NSF requirements this water heater is to be:
a) Sealed to the floor with sealant, in a smooth and easily cleanable
way, or
b) Installed with an optional leg kit that includes legs and/or
extensions that provide a minimum clearance of 6” beneath the

Be sure to smell next to the floor.
IF YOU SMELL GAS:
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any telephone in your
building.
• Immediately call your gas supplier from a neighbor’s telephone.
Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
IMPORTANT
The flow of combustion and ventilating air must not be obstructed.
Provide adequate air for combustion and ventilation. An insufficient
supply of air will cause recirculation of combustion products resulting in
air contamination that may be hazardous to life. Such a condition often
will result in a yellow, luminous burner flame, causing carboning or
sooting of the combustion chamber, burners and flue tubes with possible
damage to the water heater. When an exhaust fan is installed in the
same room with a water heater, sufficient openings for air must be
provided in the walls. Undersized openings will cause air to be drawn
into the room through the chimney, causing recirculation of combustion
products.
Confined Spaces
Confined spaces are spaces defined as having less than 50 ft.
(1.41m
Unconfined Spaces
In unconfined spaces in buildings, infiltration may be adequate to provide air
for combustion, ventilation and dilution of flue gases. However, in build ings of
tight construction (for example, weather stripping, heavily insulated, caulked,
vapor barrier, etc.), additional air may need to be provided using the methods
described above under CONFINED SPACES: All Air from Outdoors or
