GENERAL INFORMATION
This water heater must be installed in accordance with local codes. In the 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 this 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 certified 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.
CAUTION
Incorrect operation of this appliance may create a hazard to life and
property and will nullify the warranty. Do not use this appliance if any part
has been submerged in water. The plumbing professional responsible for the
installation of this water heater should be contacted to inspect the appliance
and to replace any part of the control system, including the thermostat, which
has been submerged in water. Make sure that the rating plate on the water
heater is referenced for certainty that the correct voltage is being supplied
to the water heater.
DANGER
Do not store or use gasoline or other flammable, combustible, or corrosive
vapors and liquids in the vicinity of this or any other appliance. A
sacrificial anode is used to extend tank life. Removal of this 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 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. Our products
incorporate components that are both environmentally safe and harmless to
health, so they can be disassembled as easily as possible and recycled once
they reach their final life stage. Recycling of materials reduces the quantity
of waste and the need for the production of raw materials (e.g. metals) which
requires a substantial amount of energy and causes the release of harmful
substances. Recycling procedures reduce the consumption of natural resources,
as the waste parts made of plastic and metal can be returned to various
production processes. For more information on waste disposal, please visit
your waste collection center or the store where the product was purchased.
INSTALLATION
Locating the Water Heater
WARNING
Water heaters are heat-producing appliances. To avoid damage or injury, there
shall be no materials stored against the water heater and proper care shall 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. This water heater MUST
be installed indoors out of the wind and weather. This water heater shall NOT
be installed in any location where gasoline or flammable vapors are likely to
be present unless the installation is such to eliminate the probable ignition
of gasoline or flammable vapors. The location of this water heater is of the
utmost importance. Before installing the water heater, select a location that
is accessible to water supply lines and the power supply. 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. This water
heater MUST be installed indoors. Failure to install this water heater indoors
and protected from wind and weather will void the warranty. The water heater
must be installed in the vertical position with the water fittings pointing
upward. The water heater must be positioned on the appropriate surface.
NOTE: Take into consideration also the filled weight of the water heater
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,
refrigerators, 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. 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 valve will not result in damage to
the area adjacent to the water heater or to the 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 have a minimum length and width of
at least 4 in. (10.2 cm) greater than 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 and HOT water outlet are
identified on the water heater. The fittings at the cold-water inlet and hot
water outlet have 3/4” NPT tapered male threads. Make the proper plumbing
connections between the water heater and the plumbing system in the house.
Install a shut-off valve in the cold-water supply line. The Inlet and outlet
pipes of the water heater are color-coded. The supply of cold water is marked
with a blue ring. The outlet for warm water is marked with a red ring.
CAUTION
If sweat fittings are to be used, DO NOT apply heat to the nipples on 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 3/4” X 3/4” TEMPERATURE-
PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT
RESULT FROM EXCESSIVE TEMPERATURE AND PRESSURES. If this water heater is
installed in a closed water supply system, such as the 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. When a steady stream of
water flows through 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. This water heater must be permanently connected to
the water mains and not by a hose set.
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 shall 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 comply 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. 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 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 the 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.

Electrical Connections
Before any electrical connections are made, be sure that the water heater is
full of water and that the manual shut-off valve in the cold-water supply line
is open. Check the rating plate and wiring diagram before proceeding. This
electric water heater was built and wired in accordance with the IEC testing
approvals requirements. The temperature limiting device is of the manual
reset, trip-free type and has been factory installed to interrupt all
ungrounded power supply conductors in the event of thermostat failure.
Thermostats are factory set and wired in accordance with the wiring diagram
fastened to the inside of the top access panel. The plumbing supplier in your
area ordered this heater wired at the factory to comply with existing area
codes, but local utility codes may require or allow other circuitry. Consult
your local power company to determine the correct electrical hook-up in order
to meet local utility and building codes and in order to obtain the most
economical rates. Also, check to find out if you are required to obtain a
permit before starting the installation. The following chart shows the
recommended fuse size for the maximum water heater wattage. The maximum
wattage and rated voltage are shown on the water heater data plate. The water
heater must be well grounded. Must have some means of disconnect that follow
local utility and building codes. An opening for a 3/4-inch electrical fitting
is provided for field wiring connections. Check the rating plate and diagram
before proceeding. Protection should be adequate to the electrical demand of
the heater.

SAFETY SHUT-OFF
Water heaters have a bipolar safety thermostat that works in case of abnormal heating of water. The operation of the safety thermostat causes the automatic opening of the circuit the electrical heating element, whose resetting is manual, and must be done after the elimination of the cause of the anomaly. If this anomaly occurs, call an authorized service center.
GENERAL OPERATION
Before closing the switch to allow an electric current to flow to the water heater, make certain that the water heater is full of water and that the cold- water inlet valve is open. Complete failure of the heating element(s) will result if they are not totally immersed in water at all times. Failure of the element(s) due to dry-firing is not covered by warranty. When the switch is closed, the operation of this electric water heater is automatic.
CAUTION
Scalding may occur within five (5) seconds at a temperature setting of
140°F (60°C). Care must be taken whenever using hot water to avoid scalding
injury. Certain appliances require high-temperature hot water (such as
dishwashers and automatic clothes washers).
TO FILL THE WATER HEATER
- Close the water heater drain valve (if provided) by inserting a standard flathead screwdriver into the slot and turning clockwise.
- Open the cold-water supply shut-off valve.
- Open several hot water faucets to allow air to escape from the system.
- When a steady stream of water flows from the faucets, the water heater is filled. Close the faucets and check for water leaks at the water heater drain valve, combination temperature, and pressure relief valve, and the hot and cold-water connections.
TO DRAIN THE WATER HEATER
Should it become necessary to completely drain the water heater, make sure you
follow the steps below:
- Disconnect the power supply to the water heater. Consult the plumbing professional or electric company in your area for service.
- Close the cold-water supply shut-off valve.
- Open the drain valve (if provided) on the water heater by inserting a standard flathead screwdriver into the slot and turning counter-clockwise. The drain valve has threads on the end that will allow the connection of a standard hose coupling. For those models not equipped with a drain valve, disconnect cold water inlet piping at a convenient connection location as close to an adequate drain as possible. CAUTION! THIS WATER MAY BE HOT.
- Open a hot water faucet to allow air to enter the system. To refill the water heater, refer to “TO FILL THE WATER HEATER.”
Thermostat Adjustment
Setting the Water Temperature
- The thermostat has been set at the factory at about 52 °C to reduce the risk of scald injury. We recommend this setting as this ensures the safest and most economical operation of the water heater. This way the water temperature is maintained at about 52 °C. The operation of the heater at this temperature level also results in a reduced build-up of calcium and lime, as well as reduced heat loss than is the case at higher temperatures.
- An authorized person can change the thermostat setting by removing the protective cover and turning the thermostat adjustment screw on the side of the electric water heater. Align markings on thermostat and adjustment screw to desired water temperature.
DANGER
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 the point of discharge water temperatures 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, turn off the electrical supply
to the water heater and contact a qualified service technician.
LIGHT INDICATOR
The operation of the heating element is indicated by the light indicator that
stays on until the temperature in the tank has reached the set level or until
the heater has been deliberately switched off.
ANTIFREEZING PROTECTION
When the water heater is not in use for longer periods of time, it should be
protected from freezing by setting the temperature to the minimum possible
position. Do not disconnect the power. Should you choose to disconnect the
power, the water heater should be thoroughly drained before the onset of
freezing conditions (see Draining of water).
CLEANING
It is advised to clean the outer cover with a soft cloth and a mild solution
of washing liquid. The use of abrasive or solvent cleaning fluids should be
avoided.
MAINTENANCE
IMPORTANT
The water heater should be inspected at a minimum of annually by a
qualified service technician for damaged components. DO NOT operate this water
heater if any part is found damaged. Shut off the electric power whenever the
water supply to the water heater is off. Shut off the electric power and water
supply, and drain the heater completely to prevent freezing whenever the
building is left unoccupied during the cold weather months. In order to ensure
efficient operation and long tank life, drain the water heater at least once a
month through the drain valve until the water runs clear. Failure to do this
may result in noisy operation and lime and sediment buildup in the bottom of
the tank. Check the temperature-pressure relief valve to ensure that the valve
has not become encrusted with lime. Lift the lever at the top of the valve
several times until the valve seats properly without leaking and operates
freely.
WARNING
When lifting the lever of a temperature-pressure relief valve, hot water
will be released under pressure. Be certain that any released water does not
result in bodily injury or property damage. The magnesium anode rod should be
inspected periodically and replaced when necessary to prolong tank life. The
following maintenance should be performed by a qualified service technician at
the minimum periodic intervals suggested below. In some installations, the
maintenance interval may be more frequent depending on the amount of use and
the operating conditions of the water heater. Regular inspection and
maintenance of the water heater will help to ensure safe and reliable
operation.
-
Annually, check the operation of the thermostat(s).
-
Bi-annually, check the seal around the heating elements for leaks. If there is any sign of leaking, disconnect the power supply to the water heater and contact the plumbing professional that installed this water heater or a qualified service technician.
-
At least once a year, check the combination temperature and pressure relief valve to ensure that the valve has not become encrusted with lime. Lift the lever at the top of the temperature-pressure relief valve several times until the valve seats properly without leaking and operates freely.
WARNING: When lifting the lever of the temperature-pressure relief valve, hot water will be released under pressure. Be certain that any released water does not result in bodily injury or property damage. -
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 for any reason.
-
Monthly, drain off a gallon of water from the water heater to remove silt and sediment.
WARNING: THIS WATER MAY BE HOT. -
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.
