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 un-insulated
hot water lines can waste energy and
water.
Place the water heater in such a manner
that the upper electronic control and the
lower access panels can be 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.
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.
This water heater is supplied with a water
detection system. It is recommended that
the water heater be placed in a suitable
catch pan and the water sensor rope be
placed inside the catch pan. See water
sensor section for further information.
A—Diameter of water
heater plus 2″min.
B—Maximum 2″
NOTICE: Auxiliary catch pan MUST conform to local codes.
Catch Pan Kits are available from the store where the water
heater was purchased, or any water heater distributor.
B
ATo 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.
!
NOTICE: Do not install
the water heater in attics
where the temperature
may exceed 150°F.

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 and Automatic Gas Shut-Off Devices 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 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 the 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 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 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.
!
WARNING: 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.
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.
EcoNetTM Communication Port
EcoNetTM Communication port is for
future integration with home automation,
energy management, and demand response
systems.

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
temperature sensor and temperature
limiting control (ECO) that is located
above the upper 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.

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.
