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 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 province 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, 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.
Thermostat
The thermostat of this water heater has been factory set at the
lowest position which approximates 120°F (49°C) to reduce the
risk of scald injury. The thermostat is adjustable if a different
water temperature is desired. Read all warnings in this manual
and on the water heater before proceeding.
