This appliance has been design certifi ed as complying with
American National Standard/CSA Standard for water heaters
and is considered suitable for:
Water (Potable) Heating and Space Heating: All models are
considered suitable for water (potable) heating and space heat-

HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, clothes wash-
ing, 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 requir-
ing 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,
a means such as a *mixing valve, should be used at the hot
water taps used by these people or at the water heater. Mix-
ing valves are available at plumbing supply or hardware stores.
Consult a Qualifi ed 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.
