Introduction
CAUTION
!
WA RNING
!
The location chosen for the water heater must take into consideration the
following:
LOCAL INSTALLATION REGULATIONS
This water must be installed in accordance with these instructions, local
codes, utility company requirements or, in the absence of local codes, the
latest edition of the National Electrical Code. It is available from some local
libraries or can be purchased from the National Fire Prevention Association, 1
Batterymarch Park, Quincy, MA 02269 as booklet ANSI/NFPA 70.
LOCATION
Locate the water heater in a clean dry area as near as practical to the area of
greatest heated water demand. Long uninsulated hot water lines can waste
energy and water. Place the water heater in such a manner that the front
panel can be easily removed to permit inspection and servicing such as
removal of elements or checking controls. The water heater and water lines
should be protected from freezing temperatures. Do not install the water
heater in outdoor, unprotected areas.
Installation
The water heater should not be located in an area where
leakage of the tank or connections will result in damage to
the area adjacent to it or to lower floors of the structure.
This water heater SHOULD NOT be installed in a space where
liquids which give off flammable vapors are to be used or
stored. Such liquids include gasoline, LP gas (butane and
propane), paint or adhesives and their thinners, solvents or
removers. Because of natural air movement in a room or
other enclosed space, flammable vapors can be carried from
where their liquids are being used or stored. The arc drawn
within the water heater's control can ignite these vapors
causing an explosion or fire which may result in severe burns
or death to those in range, as well as property damage.
1. INSPECT SHIPMENT — Inspect water heater for possible damage.
Check the markings on the rating plate of the water heater to be
certain the power supply corresponds to that for which the water
heater is equipped.
2. THERMAL EXPANSION — Determine if a check valve exists in the
inlet water line. It may have been installed in the cold water line as
a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the
cold water inlet line can cause what is referred to as a ”closed water
system”. A cold water inlet line with no check valve or back flow
prevention device is referred to as an ”open” water system.
As water is heated, it expands in volume and creates an increase in
the pressure within the water system. This action is referred to as
”thermal expansion”. In an ”open” water system, expanding water
which exceeds the capacity of the water heater flows back into the
city main where the pressure is easily dissipated.
A ”closed water system”, however, prevents the expanding water
from flowing back into the main supply line, and the result of ”thermal
expansion” can create a rapid, and dangerous pressure increase in
the water heater and system piping. This rapid pressure increase
can quickly reach the safety setting of the relief valve, causing it to
operate during each heating cycle. Thermal expansion, and the resulting rapid, and repeated expansion and contraction of components in
the water heater and piping system can cause premature failure of
the relief valve, and possibly the heater itself.Replacing the relief
valve will not correct the problem!
The suggested method of controlling thermal expansion is to install an
expansion tank in the cold water line between the water heater and the
check valve. The expansion tank is designed with an air cushion built
in that compresses as the system pressure increases, thereby relieving
the over pressure condition and eliminating the repeated operation of
the relief vale. Other methods of controlling thermal expansion are also
available. Contact your installing contractor, water supplier, or plumbing
inspector for additional information regarding this subject.
3. WATER SUPPLY CONNECTIONS — Refer to Fig. 2 for suggested
typical installation. The installation of unions or flexible copper con-
nectors is recommended on the hot and cold water connections so
that the water heater may be easily disconnected for servicing if
necessary. The HOT and COLD water connections are clearly marked
and are 3/4” NPT on all models. Install a shut-off valve in the cold
water line near the water heater.
IMPORTANT!! Do not apply heat to the hot or cold water connections. If
sweat connections are used, sweat tubing to adapter before fitting adapter to hot or cold water connections on heater. Any heat applied to the hot
or cold water supply fittings will permanently damage them.
4. RELIEF VALVE — A new combination temperature and pressure relief
valve, complying with the Standard for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22,
must be installed in the opening provided and marked for the purpose
on the water heater. (Refer to Fig. 2.) No valve of any type should be
installed between the relief valve and the tank. Local codes shall govern the installation of relief valves.
The pressure rating of the relief valve must not exceed 150 PSI, the
maximum working pressure of the water heater as marked on the
rating plate. The BTUH Rating of the relief valve must not be less than
the input rating of the water heater as indicated on the rating label
located on front of the heater (1 watt = 3.412 BTUH).
Connect the outlet of the relief valve to a suitable open drain so that
the discharge water cannot contact live electrical parts and to eliminate potential water damage. Piping used should be of a type approved for hot water distribution. The discharge line must be no
smaller than the outlet of the valve and must pitch downward from
the valve to allow complete drainage (by gravity) of the relief valve
and discharge line. The end of the discharge line should not be
threaded or concealed and should be protected from freezing. No
valve of any type, restriction or reducer coupling should be installed
in the discharge line.
5. TO FILL WATER HEATER — Make certain drain valve is completely
closed. Open shut-off valve in cold water supply line. Open each hot
water faucet slowly to allow air to vent from the water heater and
piping. A steady flow of water from the hot water faucet(s) indicates
a full water heater.

SAFETY PRECAUTIONS
A. Do turn off power to water heater if it has been subjected to over
heating, fire, flood or physical damage.
B. Do Not turn on water heater unless it is filled with water.
C. Do Not turn on water heater if cold water supply shut-off valve is
closed.
D. If there is any difficulty in understanding or following the OPERATION or
MAINTENANCE instructions, it is recommended that a qualified person
or serviceman perform the work.
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 dissipate such
gas and to reduce risk of injury, 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. Do not smoke or use an
open flame near the faucet at the time it is open.
1. WATER TEMPERATURE SETTING — The temperature of the water in
the water heater can be regulated by setting the temperature dial of the
adjustable surface mounted thermostats located behind the front center
panel. To comply with safety regulations the thermostats are factory set at
120° F. or less where local codes require.

Safety and energy conservation are factors to be considered when
selecting the water temperature setting of the water heater’s thermostats.
The lower the temperature setting the greater the savings in energy and
operating costs.
There is a Hot Water SCALD Potential if the thermostat is set
too high.
NOTE: Households with small children or invalids may require a 120° F.
or lower thermostat setting to prevent contact with “HOT” water.

Make certain power to water heater is OFF before removing
front center panel or top panel FOR ANY REASON.
If adjustment is necessary, turn off power to water heater, remove front
center panel and insulation exposing thermostats. The thermostat
protective covers should not be removed. Set thermostats dial pointers,
with a small screwdriver, to desired temperature. (Refer to Fig. 4.) Replace
insulation and front center panel. Turn on power to water heater.
2. SAFETY CONTROLS — The water heater is equipped with a
combination Thermostat and Temperature Limiting Control (ECO) that is
located above the heating element in contact with the tank surface. If for
any reason the water temperature becomes excessively high, the
Temperature Limiting Control (ECO) breaks the power circuit to the
heating element. Once the control opens, it must be reset manually.
The cause of the High Temperature Condition must be investigated by qualified service personnel and corrective action
taken before placing the water heater in service again.
To reset Temperature Limiting Control, turn off power to water heater,
remove front center panel and insulation. The thermostat protective
cover SHOULD NOT be removed. (Refer to Fig. 4.) Press red “RESET”

button. Replace insulation and jacket access panel(s) before turning on
power to water heater.
3. EMERGENCY INSTRUCTIONS —
If water heater has been subjected to flood, fire, or physical
damage, turn off power and water to water heater. Do not
operate the water heater again until it has been thoroughly
checked by qualified service personnel.
4. VACATION AND LONG TIME SHUT-DOWN — If the water heater is to
remain idle for an extended period of time, the power and water to the
water heater should be turned off to conserve energy. The water heater
and piping should be drained if they might be subjected to freezing
temperatures.
NOTE: Refer to “Hydrogen Gas Caution” in Safety Precautions
Section on page 6.
After a very long shut-down period, the water heater’s operation and
controls should be checked by qualified service personnel. Make certain
the water heater is completely filled before again placing it in operation .
In order to drain water heater, turn off cold water supply, then it is
necessary to open a hot water faucet or lift the handle on the relief valve
to admit air to the tank. Attach a garden hose to the drain valve on the
water heater (located behind the front center panel near the bottom of the
water heater) and direct the stream of water to a drain where it will do no
damage.
The water drained from the tank may be hot enough to present a SCALD HAZARD and should be directed to a suitable
drain to prevent injury or damage.
6. ANODE — This water heater is equipped with an anode rod designed to
prolong the life of the glass lined tank. The anode is slowly consumed
cathodically, thereby eliminating or minimizing corrosion of the glass lined
tank.
Water sometimes contains a high sulfate and/or mineral content and
together with the cathodic protection process can produce a hydrogen
sulfide or rotten egg odor in the heated water. Chlorination of the water
supply should minimize the problem.
5. DRAINING HEATER —
Shut off power to water heater before draining water.
Maintenance
Properly maintained, your water heater will provide years of dependable troublefree service. It is suggested that a routine preventive maintenance program be
established and followed by the user. It is further recommended that a periodic
inspection of the operating controls, heating element and wiring should be
made by service personnel qualified in electric appliance repair.
1. ROUTINE PREVENTATIVE MAINTENANCE
A. Most electrical appliances make some sound when in operation, even when
new. If the hissing or singing sound level increases excessively, the electric
heating element may require cleaning. Contact your installer or plumbing
contractor to inspect.
B. The area near the water heater must be kept free of flammable liquids such
as gasoline or paint thinners, adhesives or other combustible materials.
C. At least once a year, lift and release the lever handle on the temperature
pressure relief valve, located near the top of the water heater, to make
certain the valve operates freely and allow several gallons to flush through
discharge line. Make certain the discharged water is directed to an open
drain.
Before manually operating the relief valve, make certain no
one will be exposed to the danger of coming in contact with
the hot water released by this valve. The water may be hot
enough to create a SCALD hazard. The water released should
be directed to a suitable drain to prevent injury or damage.
NOTE: Do not remove the anode rod from the water heater’s tank,
except for inspection and/or replacement, as operation with the
anode rod removed will greatly shorten the life of the glass lined
tank and will exclude warranty coverage.
NOTE: If the temperature and pressure relief valve on the water heater
discharges periodically, this may be due to thermal expansion in a
“Closed” water system. Contact the water supplier or your plumbing
contractor on how to correct this. DO NOT plug the relief valve outlet.
D. A water heater’s tank can act as a settling basin for solids suspended in the
water. It is, therefore, not uncommon for hard water deposits to accumulate
in the bottom of the tank. It is suggested that a few quarts of water be
drained from the water heater’s tank every month to clean the tank of these
deposits.
E. Rapid closing of faucets or solenoid valves in automatic water using
appliances can cause a pounding “water hammer” sound. “Water hammer”
can be described as a banging noise heard in a water pipe following an
abrupt alteration of the flow with resulting pressure surges. Strategically
located risers in the water pipe system can be used to minimize the
problem. Also water hammer arresting devices are usually available from
your plumber or local plumbing supply store.
2. ANODE ROD INSPECTION — The anode rod should be removed from the
water heater’s tank annually for inspection and replaced when more than 6”
of core wire is exposed at either end of the rod. Refer to Fig. 2 or 3 for anode
rod location. Make certain cold water supply is turned off before removing
anode rod.
