SAFETY PRECAUTIONS
5
Installing the water heater.
The location chosen for the water heater must take into consideration the following:
Local Installation Regulations
This water heater must be installed
in accordance with these instructions,
local codes, utility 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
Protection Association, 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 thermostat and element
access panels can be removed to
permit inspection and servicing such
as removal of elements or checking
controls.
The water heater has been sized to fit
through narrow doorways and to be
installed in tight/spaces. The energy
cover should be installed in the final
location.
The water heater and water lines
should be protected from freezing
temperatures. DO NOT install the
water heater in outdoor, unprotected
areas.
Make certain the floor underneath
the water heater is strong enough to
sufficiently support the weight of the
water heater once it is filled with water.
!
CAUTION: 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. Where such
areas cannot be avoided, it is
recommended that a suitable catch
pan, adequately drained, be installed
under the water heater.
A— Diameter of water
heater plus 2″ min.
B— Maximum 2″
NOTICE: Auxiliary drain pan MUST conform to local codes.
Drain Pan Kits are available from the store where the water heater was purchased,
or any water heater distributor.
B
A
To open drain, line
should be at least 3/4″
ID and pitched for
proper drainage.
Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating
plate of the water heater to be certain the power supply corresponds to the water
heater requirements.
6
Installing the water heater.
Typical Installation
Thermal Expansion
Determine if a check valve exists in the
inlet water line. Check with your local
water utility. 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 (refer to the illustration below).
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 valve. Other methods of controlling
thermal expansion are also available.
Contact your installing contractor, water
supplier or plumbing inspector for
additional information regarding this
subject.
NOTICE: DO NOT
apply heat to the hot or
cold water connections.
If sweat connections are
used, sweat tubing to
adapter before fitting
adapter to the water
connections on heater.
Any heat applied to the
water supply fittings will
permanently damage
the dip tube and/or heat
traps.
Water Supply Connections
Refer to the illustration below for suggested typical installation. The installation of
unions or flexible copper connectors 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.

!
WARNING: 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.
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves
for Hot Water Supply Systems, ANSI Z21.22, is supplied and must be installed in the opening provided and
marked for the purpose on the water heater. No valve of any type should be installed between the relief
valve and the tank. Local codes shall govern the installation of relief valves.
Relief Valve
The Btu/h 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 the front of the
heater
(1 watt=3.412 Btu/h).
Connect the outlet of the relief valve
to a suitable open drain so that the
discharge water cannot contact live
electrical parts or persons 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.
To Fill the Water Heater
Make certain the drain valve on the
water heater is completely closed.
Open the shut-off valve in the cold
water supply line.
Open each hot water faucet slowly to
allow the 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.
Condensation
Condensation can form on the tank
when it is first filled with water.
Condensation might also occur with a
heavy water draw and very cold inlet
water temperature.
This condition is not unusual, and will
disappear after the water becomes
heated. If, however, the condensation
continues, examine the piping and
fittings for possible leaks.
!
WARNING: DO NOT
turn on the electrical
supply or operate this
water heater unless it is
completely full of water.
The tank must be full of
water before heater is
turned on. The water
heater warranty does not
cover damage or failure
resulting from operation
with an empty or
partially empty tank.

recommended that a qualified
person or serviceman perform the
work.
Operating the water heater.
CAUTION: 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 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.
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.
CAUTION: The cause of the high
temperature condition must be
investigated by qualified service
technician and corrective action must
be taken before placing the water
heater in service again.
To reset the temperature limiting
control:
Turn off the power to the water
heater.
Remove the jacket access panel(s)
and insulation.
The thermostat protective cover
should not be removed.
Press the red RESET button.
Replace the insulation and jacket
access panel(s) before turning on
the power to the water heater.
WARNING: If the

DANGER: There is a
hot water scald potential if
the thermostat is set too
high. Households with small
children, disabled, or
elderly persons may require
a 120°F (49°C) or lower
thermostat setting to
prevent contact with HOT
water.
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 thermostat(s) located
behind the jacket access panel(s).
Dual element heaters have two
thermostats.
Safety and energy conservation are
factors to be considered when selecting
the water temperature setting of the
water heater’s thermostat(s). The lower
the temperature setting, the greater the
savings in energy and operating costs.
However, for the best first hour hot
water delivery, the following thermostat
settings are recommended. Upper
thermostat: 125°F (52°C) - 130°F
(54°C), Lower thermostat: 120°F (49°C).
To comply with industry codes and
standards the thermostat(s) are factory
set at 120°F (49°C) or less where local
codes require. This is the recommended
starting point.
Contact (such as at the water use
fixture) with water temperatures above
125°F (52°C) can cause severe burns
or death from scalding. Be sure to read
and follow the warnings outlined in this
manual and on the label on the water
heater. This label is located on the water
heater near the thermostat access panel.
Mixing valves are recommended for
reducing point of use water temperature
by mixing hot and cold water in
branch water lines. It is recommended
that a mixing valve complying
with the Standard for Temperature
Actuated Mixing Valves for Hot Water
Distribution Systems, ASSE 1017 be
installed. See page 4 for more details
and contact a licensed plumber or the
local plumbing authority for further
information.
The chart below may be used as a
guide in determining the proper water
temperature for your home.

Care and cleaning of the water heater.
Draining the Water Heater
CAUTION: Shut off power to the
water heater before draining water.
DANGER: Before manually
operating the relief valve, make
certain no one will be exposed to the
hot water released by the valve. 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.
In order to drain the water heater, turn
off the cold water supply. 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 and direct
the stream of water to a drain. Open
the valve.
Routine Preventative Maintenance
Properly maintained, your water heater
will provide years of dependable
trouble-free 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.
Most electrical appliances, even
when new, make some sound when
in operation. If the hissing or singing
sound level increases excessively, the
electric heating element may require
cleaning. Contact a qualified installer or
plumbing contract to inspect.
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. Allow several
gallons to flush through the discharge
line to an open drain.
A water heater’s tank can act as a
setting 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.
Rapid closing of faucets or solenoid
valves in automatic water using
appliances can cause a banging noise
heard in a water pipe. Strategically
located risers in the water pipe system
or water hammer arresting devices can
be used to minimize the problem.
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.
Make sure the cold water supply is
turned off before removing anode rod.
DANGER: 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 the valve. The
water may be hot enough
to create a scald hazard.
The water should be
released into a suitable
drain to prevent injury or
property damage.
NOTICE: If the
temperature and pressure
relief valve on the hot
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.
15
Care and cleaning of the water heater.
Vacation and Extended Shut-Down
If the water heater is to remain idle for
an extended period of time, the power
and water to the appliance should
be turned off to conserve energy
and prevent a build-up of dangerous
hydrogen gas.
The water heater and piping should be
drained if they might be subjected to
freezing temperatures.
After a 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 again before
placing
it in operation.
NOTICE: Refer to the
Hydrogen Gas Caution in
the Operating Instructions.
Anode Rod
This water heater is equipped with an
anode rod designed to prolong the life
of the glass lined tank. The anode rod is
slowly consumed, thereby eliminating
or minimizing corrosion of the glass
lined tank.
Water sometimes contains a high sulfate
and/or mineral content and together
with 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.
NOTICE: 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.
