absence of local codes, install this water heater in accordance with the N.E.C.
Reference Book (latest edition).
The warranty for this water heater is in effect only when the water heater is
installed, adjusted and operated in accordance with these Installation and
Operating Instructions. The manufacturer will not be held liable for damage
resulting from alteration and/or failure to comply with these instructions.
This water heater has been designed and listed for the purpose of heating
potable water. The installation and use of this water heater for any purpose
other than the heating of potable water may cause damage to the water heater
and create a hazardous condition and nullify the warranty.
Do not use this appliance if any part has been under water. Immediately call a

General Information continued-
A sacrificial anode(s) is used to extend tank life. Removal of any 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 impurities in the water. If this should happen, an
alternative anode(s) 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 its components for
possible damage. DO NOT install any damaged components. If damage is
evident, please contact the supplier where the water heater was purchased or
the manufacturer listed on the rating plate for replacement parts.

INSTALLATION
Locating The Water Heater
Thiswater 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 ignition of gasoline or flammable vapors.
The location for the installation of this water heater is of utmost importance.
Before installing this water heater, consult 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 a power supply and water connections. It is recommended that the water
heater be located near the center of greatest hot water usage to prevent heat
loss through the pipes. DO NOT locate the water heater where water
lines could be subjected to freezing temperatures. Locate the water
heater so that access panels and drain valves are accessible.
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 or 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.
Locating The Water Heater continued-
This water heater must be located in an area where leakage of the tank or
water line connections and the combination temperature and pressure relief
WARNING
Water heaters are heat-producing appliances. To avoid damage or injury,
there must be no materials stored against the water heater and proper care
must be taken to avoid unnecessary contact (especially by children) with the
water heater. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE
MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR
STORED IN THE VICINITY OF THIS WATER HEATER OR ANY LOCATION
FROM WHICH FUMES COULD REACH THE WATER HEATER.

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 be no greater than 1 1/2 in. (3.8 cm) deep and have a minimum length
and width of at least 4 in. (10.2 cm) measured from the jacket of 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 pitched for proper drainage.
Water Connections
NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE
MAIN WATER SUPPLY VALVE.
After shutting the main water supply valve, 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 line connects to the inlet nipple
at the base of the water heater. The hot water outlet line connects to the
nipple on top of the water heater. The fittings at the cold water inlet and hot
water outlet are dielectric waterway fittings with tapered male threads. Make
the proper plumbing connections between the water heater and the plumbing
system in the structure. Install a shut-off valve in the cold water supply line.
If this water heater is installed in a closed water supply system, such as 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. After a steady stream of
water flows from 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.
Water Connections continued-
CAUTION
If sweat fittings are to be used, 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.
IMPORTANT
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED TEMPERATURE-
PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER
FROM ANY CLAIM, WHICH MIGHT RESULT FROM EXCESSIVE
TEMPERATURE AND PRESSURES.

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
for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply
Systems, ANSI Z21.22, 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 shall
also have an hourly rated temperature steam BTU discharge capacity not
less than the hourly input 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 (15.3 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 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 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 a hot water system served by this
water heater that has not been used for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions, it is
recommended that the hot water faucet be opened for several
minutes at the kitchen sink before using any electrical appliance
connected to the hot water system. If hydrogen is present, there will
probably be an unusual sound such as air escaping through the pipe
as the water begins to flow. There should be no smoking or open
flame near the faucet at the time it is open.
CAUTION
INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET
TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME
EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF
SCALD INJURY.
