DANGER!
WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the water
temperature setting of water heater’s thermostat. Water temperatures above 125°F can
cause severe burns or death from scalding. Be sure to read and follow the warnings
outlined on the label pictured below. This label is also located on the water heater near
the thermostat access panel.

Children, disabled and elderly are
at highest risk of being scalded.
See instruction manual before
setting temperature at water
heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, see manual.

120°F More than 5 minutes
125°F 1½ to 2 minutes
130°F About 30 seconds
135°F About 10 seconds
140°F Less than 5 seconds
145°F Less than 3 seconds
150°F About 1½ seconds
155°F About 1 second

in determining the proper water temperature for your
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
attention to the Safety Instructions. Failure to follow these warnings could result in
serious bodily injury or death. Should you have problems understanding the instructions
in this manual, or have any questions, STOP, and get help from a qualified service
technician, or the local electric utility.
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.
READ AND FOLLOW THIS SAFETY INFORMATION
CAREFULLY.

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.

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.
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.

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.
