A sacrificial anode is used to extend tank life. The removal of this anode, for
any reason, will nullify the warranty. In areas where water is unusually active,
an odor may occur at the hot water faucet due to a reaction between the
sacrificial anode and the impurities in the water. If this should happen, an
alternative anode may be purchased from the supplier that installed this water
heater. This will minimize the odor while protecting the tank. Additionally, the
water heater should be flushed with appropriate dissolvers to eliminate any
bacteria.
IMPORTANT
Before proceeding, please inspect the water heater and components for
possible damage. DO NOT install any damaged components. If damage
is evident then please contact the supplier where the water heater was

INSTALLATION
LOCATING THE WATER HEATER
This water heater MUST NOT be installed in any location where gasoline
or flammable vapors are likely to be present, unless the installation is
such to eliminate the probable ignition of gasoline or flammable vapors.
Water heaters in residential garages must be installed and located, or
protected, to avoid physical damage. For other installations refer to
local codes. In the absence of local codes, the water heater must be
installed in compliance with the National Fuel Gas Code, (ANSI Z223.1-
Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation
Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code
(Latest Edition).
The location of this water heater is of the utmost importance. Before installing
this water heater read the Installation section of these instructions. After
reading these Installation and Operating Instructions, select a location for the
water heater where the floor is level and is easily accessible to gas and water
supply lines. DO NOT locate the water heater where water lines could be
subjected to freezing temperatures. Make sure the cold water pipes are
not located directly above the gas control so that condensate during
humid weather does not drip on the controls.
This water heater MUST be installed indoors out of the wind and
weather.
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 water heater.
WARNING
Water heaters are heat producing appliances. To avoid damage or injury
there shall be no materials stored against the water heater or vent-air
intake system and proper care shall be taken to avoid unnecessary contact
(especially by children) with the water heater and vent-air intake
components. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE
MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR
STORED IN THE VICINITY OF THIS WATER HEATER, VENT-AIR
INTAKE SYSTEM OR IN ANY LOCATION FROM WHICH FUMES
COULD REACH THE WATER HEATER OR VENT-AIR INTAKE
SYSTEM.

Installation (Locating The Water Heater) continued-
Note: For California installation this water heater must be braced,
anchored, or strapped to avoid falling or moving during an earthquake.
See instructions for correct installation procedures. Instructions may be
obtained from California Office of the State Architect, 400 P Street,
Sacramento, CA 95814.
Water heater corrosion and component failure can be caused 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.
WARNING
Liquefied petroleum gases/propane gas are heavier than air and will
remain at floor level if there is a leak. Basements, crawl spaces, closets
and areas below ground level will serve as pockets for accumulation of
leaking gas. Before lighting, smell all around the appliance area for gas.
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.
DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

Installation (Locating The Water Heater) continued-
Proper venting practices must be considered when selecting a location for this
water heater. For exact venting specifications, please consult the Venting
section 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.
WARNING
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE 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
professional for more information.

VENTING
This water heater has been shipped with a draft diverter for which it was
designed with reference to the horizontal and vertical planes. If removed, the
draft diverter must be replaced in the same position and secured to the jacket
top by the screws with which it was installed.
WARNING
The venting system must be installed properly following all local codes or in
the absence of local codes, the latest edition of the National Fuel Gas Code
(ANSI Z223.1- latest edition), or in Canada, The Natural Gas and Propane
Installation Code (B149.1-00 latest edition). Failure to properly install the
venting system could result in property damage, personal injury, or death.
WARNING
Carefully inspect the venting system of a replacement water heater
installation before connecting to the venting system. All joints in the vent
connector must be securely fastened with screws and fit tightly together.
Inspect the venting system for signs of deterioration (rust and perforation)
and replace any sections that are not in good condition.
The chimney must be lined and in good condition. Check to make sure the
venting system is properly sized for the water heater. If the venting system
was previously sized for another gas appliance that has been removed, the
venting system may now be too large. Refer to the latest edition of the
National Fuel Gas Code (ANSI Z223.1-latest edition), or in Canada, the
Natural Gas and Propane Installation Code (B149.1-00 latest edition) for the
correct sizing of venting systems and common venting with another gas
appliance.
Do not vent this water heater into the venting system of another gas
appliance designed to vent under positive pressure.
The water heater should be installed as close as practical to the venting
system to minimize the vent connector length required. Refer to local codes
for the distance limitations on vent connector lengths.
At the completion of the water heater installation, the burner and venting
system must be checked for proper operation with all other commonly
vented appliances in operation. Check for spillage of flue products around
the outside relief opening of the drafthood after several minutes of
operation. The flame from a match should be drawn into the drafthood. Do
not use the water heater or connected equipment if spillage is detected until
the problem is corrected. Refer to the latest edition of the National Fuel Gas
Code, or in Canada, the Natural Gas and Propane Installation Code for
complete details on the “Procedure to Be Followed to Place Equipment in
Operation”.
