home.
DANGER: Households with small children,
disabled,
or elderly persons may require a 120°F or lower
thermostat setting to prevent contact with “HOT”
water.
The temperature of the water in the heater is
regulated by the adjustable surface mounted
thermostat(s) located behind the jacket access
panel(s). Dual element heaters have two thermostats.
To comply with safety regulations the thermostat(s)
were set at 120°F before the water heater was
shipped from the factory.

IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
For your safety, the information in this manual must be followed to minimize the risk of
fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of
life.
Be sure to read and understand the entire Use and Care Manual before attempting
to install or operate this water heater. It may save you time and cost. Pay particular

FOR INSTALLATIONS IN THE STATE OF CALIFORNIA
California Law requires that residential water heaters must be braced, anchored or
strapped to resist falling or horizontal displacement due to earthquake motions. For
residential water heaters up to 52 gallon capacity, a brochure with generic earthquake
bracing instructions can be obtained from: Office of the State Architect, 400 P Street,
Sacramento, CA 95814 or you may call 916-324-5315 or ask a water heater dealer.
However, applicable local codes shall govern installation. For residential water heaters
of a capacity greater than 52 gallons, consult the local building jurisdiction for acceptable
bracing procedures.
SAFETY PRECAUTIONS
Have the installer show you the location of the circuit breaker and how to shut it off if
necessary. Turn off the circuit breaker if the water heater has been subjected to overheating,
fire, flood, physical damage or if the ECO fails to shut off.
● Read this manual entirely before installing
or operating the water heater.
● Use this appliance only for its intended
purpose as described in this Use and Care
Manual.
● Be sure your appliance is properly installed
in accordance with local codes and the
provided installation instructions.
● DO NOT attempt to repair or replace
any part of your water heater unless it is
specifically recommended in this manual.
All other servicing should be referred to a
qualified technician.
● DO NOT turn on the electrical supply
or operate this water heater unless it is
completely full of water.

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
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 and water lines should
be protected from freezing temperatures.
Do not install the water heater in outdoor,
unprotected areas.
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.
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.
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.

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.
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.

Installing the water heater.
Vacuum Relief Va lve
If required, install per local codes
instructions.
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.
