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

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.
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.

VENTING
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”.
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.

Venting continued-
This water heater must be connected to a lined masonry chimney or venting
system approved by local codes or ordinances. The vent connector used to
attach the draft diverter outlet to the chimney or approved vent must be of the
same diameter as the draft diverter outlet or larger. For proper venting in
certain installations, a larger vent connector may be needed. Consult venting
tables in ANSI standard (Z223.1-or latest edition), National Fuel Gas Code
and CAN/CGA (B149.1 or B149.2-latest editions) Natural Gas and Propane
Installation Code, or local code officials for proper application for your area.
Combustion Air Supply
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!
IMPORTANT
The flow of combustion and ventilating air must not be obstructed.
• Do not block or in any way restrict jacket air inlet slots located at the
bottom front of the water heater.
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 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.3 of space per
1,000 BTU (1.41m3/.29kw) per hour of input.
Unconfined Spaces
In unconfined spaces in buildings, infiltration may be adequate to provide air
for combustion, ventilation and dilution of flue gases. However, in buildings 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
SPECIALLY ENGINEERED INSTALLATIONS.
All Air From Inside the Building: The confined space shall be provided with
two permanent openings communicating directly with an additional room(s) of
sufficient volume so that the combined volume of all spaces meets the criteria
for an unconfined space. The total input of all gas utilization equipment
installed in the combined space shall be considered in making this
determination. Each opening shall have a minimum free area of 1 square inch
per 1000 BTU (6.45cm2/.29kw) per hour of the total input rating of all gas
utilization equipment in the confined space, but not less than 100 square
inches (645cm2). One opening shall be within 12 inches (31cm) of the top
and one within 12 inches (31cm) of the bottom of the enclosure.
All Air From Outdoors: The confined space shall be provided with two
permanent openings, one commencing within 12 inches (31cm) of the top and
one commencing within 12 inches (31cm) from the bottom of the enclosure.
The openings shall communicate directly, or by ducts, with the outdoors or
spaces (crawl or attic) that freely communicate with the outdoors.
1. When directly communicating with the outdoors, each opening shall have
a minimum free area of 1 square inch per 4000 BTU (6.45cm2/1.2kw) per
hour of total input rating of all equipment in the enclosure.
2. When communicating with the outdoors through vertical ducts, each
opening shall have a minimum free area of 1 square inch per 4000 BTU
(6.45cm2/1.2kw) per hour of total input rating of all equipment in the
enclosure.
3. When communicating with the outdoors through horizontal ducts, each
opening shall have a minimum free area of 1 square inch per 2000 BTU
(6.45cm2/.6kw) per hour of total input rating of all equipment in the
enclosure.
4. When ducts are used, they shall be of the same cross-sectional area as
the free area of the openings to which they connect. The minimum
dimension of rectangular air ducts shall be not less than 3 inches (7.5cm)
Specially Engineered Installations
The requirements noted under CONFINED SPACES above shall not
necessarily govern when special engineering, approved by the authority
having jurisdiction, provides an adequate supply of air for combustion,
ventilation, and dilution of flue gases.

WATER CONNECTIONS
Note: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE
MAIN WATER SUPPLY VALVE.
After shutting off the main water supply, open a faucet to relieve the water line
pressure to prevent any water from leaking out of the pipes while making the
water connections to the water heater. After the pressure has been relieved,
close the faucet. The COLD water inlet and HOT water outlet are identified on
the top of the water heater. The fittings at the cold water inlet and hot water
outlet are dielectric waterway fittings with 3/4” NPT male thread. Make the
proper plumbing connections between the water heater and the plumbing
system to the house. Install a shut-off valve in the cold water supply line.
CAUTION
If sweat fittings are to be use, DO NOT apply heat to the nipples on top of
the water heater. Sweat the tubing to the adapter before fitting the adapter
to the water connections. It is imperative that heat is not applied to the
nipples containing a plastic liner.
WARNING
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4”
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM, WHICH MIGHT RESULT FROM
EXCESSIVE TEMPERATURE AND PRESSURES.
If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold water supply, provisions shall be
made to control thermal expansion. DO NOT operate this water heater in a
closed system without provisions for controlling thermal expansion. Your
water supplier or local plumbing inspector should be contacted on how to
control this situation
After installation of the water lines, open the main water supply valve and fill
the water heater. While the water heater is filling, open several hot water
faucets to allow air to escape from the water system. When a steady stream
of water flows through the faucets, close them and check all water
connections for possible leaks. NEVER OPERATE THE WATER HEATER
WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH WATER.

but not less than a combination temperature and pressure relief valve
certified by a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment or materials as
meeting the requirements of the Standard for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 or the
Standard CAN1-4.4. Temperature and Pressure and the Standard CAN1-
4.4, Temperature, Pressure, Temperature and Pressure Relief Valves and
Vacuum Relief Valves. The combination temperature and pressure relief
valve shall be marked with a maximum set pressure not to exceed the
maximum working pressure of the water heater. The combination
temperature and pressure relief valve shall also have an hourly rated
temperature steam BTU discharge capacity not less than the hourly rating
of the water heater.
Install the combination temperature and pressure relief valve into the
opening provided and marked for this purpose on the water heater.
Note: Some models may already be equipped or supplied with a
combination temperature and pressure relief valve. Verify that the
combination temperature and pressure relief valve complies with local
codes. If the combination temperature and pressure relief valve does not
comply with local codes, replace it with one that does. Follow the
installation instructions above on this page.
Install a discharge line so that water discharged from the combination
temperature and pressure relief valve will exit within six (6) inches (15.2
cm) above, or any distance below the structural floor and cannot contact
any live electrical part. The discharge line is to be installed to allow for
complete drainage of both the combination temperature and pressure
relief valve and the discharge line. The discharge opening must not be
subjected to blockage or freezing. DO NOT thread, plug or cap the
discharge line. 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.
Do not place a valve between the combination temperature and pressure
relief valve and the tank.

WARNING
Hydrogen gas can be produced in an operating water heater that has
not had water drawn from the tank for a long period of time (generally
two weeks or more). Hydrogen gas is extremely flammable. To
prevent the possibility of injury under these conditions, we
recommend the hot water faucet to be open for several minutes at the
kitchen sink before you use any electrical appliance, which is
connected to the hot water system. If hydrogen is present, there will
be an unusual sound such as air escaping through the pipes as hot
water begins to flow. Do not smoke or have open flame near the
faucet at the time it is open.
This water heater can deliver scalding temperature water at any faucet in the
system. Be careful whenever using hot water to avoid scalding injury. Certain
appliances such as dishwashers and automatic clothes washers may require
increased temperature water. By setting the thermostat on this water heater
to obtain the increased temperature water required by these appliances, the
potential for scald injury increases. To protect against injury, you should
install an ASSE approved mixing valve in the water system. This valve will
reduce point of discharge temperature by mixing cold and hot water in branch
supply lines. Such valves are available from the manufacturer of this water
heater or a local plumbing supplier. Please consult with a plumbing
professional.

Gas Connections
The gas supply lines must meet all requirements of 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 minimum permissible gas supply pressure for the purpose of input adjustment is
one (1.0) inch (0.25 kPa) water column above the operating manifold pressure. See
the rating plate and gas valve for the manifold pressure and gas type. The maximum
permissible gas supply pressure is fourteen (14.0) inches (3.5 kPa) water column for
natural gas and liquefied petroleum gases/propane gas.
1. Connect this water heater only to the type of gas (Natural or Propane gas) as
shown on the rating plate. Use clean black iron pipe or equivalent material
approved by local codes and ordinances. (Dirt and scale from the pipe can enter
the gas valve and cause it to malfunction). The inlet gas line must have a
minimum length of three (3) inches (7.6 cm) drip leg (sediment trap) installed as
close to the water heater’s gas valve as possible. A ground joint union must be
installed as close to the water heater as possible in the gas supply line feeding the
water heater to permit servicing of the water heater. Compounds used on the
threaded joints of the gas piping must be resistant to the action of liquefied
petroleum gases/propane gas. DO NOT apply pipe dope to the gas valve inlet and
make certain that no pipe dope has become lodged in the inlet screen of the gas
valve. Extreme care must be taken to ensure no pipe dope enters the gas valve.
Avoid excessive torque when tightening the gas supply line to the gas valve.
Excessive torque may result in cracking of the gas valve housing and could create
a gas leak. When tightening gas supply line to L.P. control, it is recommended to
hold the inlet body of the control securely with an adequate wrench. The
suggested maximum torque is 31.5 ft. lbs. (4.4 kg-m).
WARNING
The manufacturer of this water heater will not be liable for any damage or injury
caused as a result of a cracked gas inlet as a result of excessive torque.
2. This water heater and its gas connection must be leak tested before placing the
water heater in operation. Check for gas leaks with a soap and water solution and
a brush or a commercial leak detector fluid. NEVER USE A MATCH OR OPEN
FLAME FOR TESTING!
CAUTION
The water heater and individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of the system at test pressures in
excess of 1/2 psi (3.5 kPa). The water heater must be isolated from the gas supply
piping system by closing its manual shutoff valve during any pressure testing of the
gas supply system at test pressures equal to or less than 1/2 psi (3.5 kPa). The
supply line must be capped when not connected to the water heater.
3. While checking for leaks care must be taken to prevent solution from
contacting the electrical connections at the control. If electrical connections at the
control become wet, they must be thoroughly dried before attempting to operate
the water heater.

General Operation continued-
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five (5)
seconds at a temperature setting of 140°F (60°C). To protect against hot water
injury, install an ASSE approved mixing valve in the water system. This valve will
reduce point of discharge temperature by mixing cold and hot water in branch
water lines. A licensed plumbing professional or local plumbing authority should
be consulted.
Note: This water heater is equipped with an energy cut out device to prevent
overheating. Should overheating occur or the gas supply fail to shut off, turn
off the manual gas control valve to the appliance and call a qualified service
technician.
Note: Whenever the water heater is filled with cold water, condensate will
form on the cool tank surface and drops of water will fall on the hot burner
and combustion chamber surfaces producing a “sizzling” noise.
Condensation is normal and does not indicate a leak. It will disappear when
the tank becomes heated.
BURNER FLAME CHECKS
Steel Burner: These models are equipped with self adjusting air mixture and
do not have an adjustable air shutter (See Figure 6). At periodic intervals, a
visual check of the main burner and pilot flames should be made to determine
if they are burning properly. The main burner flame should light smoothly
from the pilot.

MAINTENANCE
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 system.
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.
IMPORTANT
The water heater should be inspected at a minimum annually by a
qualified service technician for damaged components and/or joints not
sealed. DO NOT operate this water heater if any part is found damaged
or if any joint is found not sealed.
The following maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on
the amount of use and the operating conditions of the water heater. Regular
inspection and maintenance of the water heater and vent-air intake system
will help to insure safe and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air MUST NOT be restricted.
Make sure slots in jacket are open and unobstructed. Clear jacket slot
openings of any dirt, dust, or other restrictions. WARNING! The ventilation
air system may be HOT.
3. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
4. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See Burner Flame Check
section of this installation and operation manual. If sooting or other
burner anomalies are evident, shut down the water heater by turning off
the gas per the instructions listed in this manual or as listed on the water
heater.
5. Annually remove the inner door and main burner assembly to clean
orifices and related parts of any dirt or other foreign material. Inspect the
burner ports for obstructions or debris and clean with a wire brush as
needed. Wire brush and/or vacuum clean the combustion chamber as
needed to remove scale deposits and debris. NOTE: It is imperative for
proper operation of the water heater that the inner door be replaced in the
original location, making certain the resetable thermal switch is properly
connected to the gas control wire leads provided.

Maintenance continued-
WARNING
• Do not operate water heater with jumpered, altered, loosely
tightened or absent controls and/or components.
• Do not operate water heater with replacement controls and/or
components, which are not exact duplicates or original equipment.
• Thoroughly inspect and replace, (as needed) burner inner door
gasket and/or sight window gasket any time burner inner door is
removed or disturbed.
•
Replace water heater if involved in flammable vapors incident.
WARNING
When lifting lever of the combination temperature and pressure relief
valve, hot water will be released under pressure. Be careful that any
released water does not result in bodily injury or property damage.
6. At least once a year, check the combination temperature and pressure
relief valve to insure that the valve has not become encrusted with lime.
Lift the lever at the top of the valve several times until the valve seats
properly without leaking and operates freely.
WARNING! THIS WATER MAY BE HOT.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing
inspector on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.
9. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected
periodically (every 2 years) and replaced when necessary to prolong tank
life. Water conditions in your area will influence the time interval for
inspection and replacement of the anode rod. Contact the plumbing
professional who installed the water heater or the manufacturer listed on
the rating plate for anode replacement information. The use of a water
softener may increase the speed of anode consumption. More frequent
inspection of the anode is needed when using softened (or phosphate
treated) water.
10. The vent system must be inspected at least once a year to ensure against
leakage of exhaust products.
