Installation continued-

DO NOT install the water heater in any location where gasoline or flammable
vapors are likely to be present. This water heater MUST be installed indoors out
of the wind and weather.

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.

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.

Installation continued-

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.

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, suitable drain pan, adequately drained, 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 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.

Minimum Clearances

Failure to adhere to these installation and operating instructions may
create a hazard to life and property and will nullify the warranty.

This installation must allow access to the front of the water heater and adequate
clearance must be provided for servicing and operating this water heater. The water
heater may be installed on either a combustible or non-combustible floor. If the water
heater is to be installed directly on carpeting, it must be installed on top of a metal or
wood panel (or equivalent) extending beyond the full width and depth of the appliance
by at least 3 inches (7.6 cm) in any direction or, if the appliance is to be installed in an
alcove or closet, the entire floor must be covered by the panel, increase distances to
provide clearance for servicing.

Combustion Air Supply continued­ All combustion air must be supplied from outdoors by one of the following

installation methods and as illustrated in Figure 2. The flow of combustion and
ventilating air must not be obstructed. Adequate air must be supplied 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 heater.

A minimum 34 in2 (86.4cm2) opening area is required to supply fresh air to the
water heater for combustion. Cut a 4” x 8 1/2” (10.2cm x 21.6cm) rectangular
opening in the outside access door panel with the bottom side of the opening
being 6” (15.3cm) from the bottom access door panel. A protective cover for
this fresh air opening is suggested to resist the entrance of rodents.

WARNING

Be sure protective cover still allows adequate fresh air opening area.

The water heater is to be secured in place using the supplied sheet metal
strapping and screws. Fasten the base of the water heater to the floor using
the screws provided. The perforated metal strapping must be fastened to the
top of the water heater and to the adjacent walls with the screws provided (See
Figure 2).

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 is identified on the side of the water
heater and HOT water outlet is 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.

WARNING

For protection against excessive temperatures and pressure, install temperature
and pressure protective equipment required by local codes, 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 must 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 must 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, you may create the potential for
scald injury. 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 m ust be taken t o prevent solut ion f rom
cont act ing t he electrical connect ions at t he cont rol. If electric al connections at
t he cont rol become w et , they must be t horoughly dried before attempt ing to
op erate t he w ater h eater .

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.

to insure that the valve has not become encrusted with lime. Lift the lever at the
lever at the top of the valve several times until the valve seats properly without
leaking and operates freely.

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

FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF COMBINATION GAS
CONTROL, BURNERS OR GAS PIPING. REFER REPAIRS TO A
QUALIFIED SERVICE TECHNICIAN.
