HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to a
temperature which will satisfy space heating, 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 infirm, or physically/mentally disabled. If anyone using hot water
in your home fits 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 satisfies your hot water
needs, a means 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 from your local plumbing contractor. Consult a Qualified
Installer or Service Agency. Follow mixing valve manufacturer's
instructions for installation of the valves. Before changing the factory
setting on the thermostat, read the "Temperature Regulation" section
in this manual.
