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.

 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.

 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.
