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 handicapped. 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, shall be used at the hot water taps used by these
people or at the water heater. Mixing valves are available 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.
