Temperature Regulation
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature which
will satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact. Some
people are more likely to be permanently injured by hot water
than others. These include the elderly, children, the infi rm, or
physically/mentally handicapped. If anyone using hot water in
your home fi ts into one of these groups or if there is a local code
or state law requiring a certain temperature water at the hot water
tap, then you must take special precautions. In addition to using
the lowest possible temperature setting that satisfi es your hot
water needs, some type of tempering device, such as a mixing
valve, should be used at the hot water taps used by these people
or at the water heater. Mixing valves are available at plumbing
supply or hardware stores. Follow manufacturers instructions for
installation of the valves, Before changing the factory setting of
the thermostat see Temperature Settings table at right.
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
Thermostats
The thermostat of this water heater has been factory set at a
position which approximates 120°F (49°C), to reduce the risk
of scald injury.
The thermostat is factory set at a position which approximates
120°F (49°C), and is adjustable if a different water temperature
is desired. Read all warnings in this manual and on the water
heating before proceeding.
