GENERAL SAFETY PRECAUTIONS
To meet residential water use needs, the temperature
on this water heater is adjustable up to 160°F (71°C).
However, water temperatures over 125°F (52° C) can cause
severe burns instantly or death from scalds. This is the
preferred starting point for setting the control for supplying
general purpose hot water.
Safety and energy conservation are factors to be
considered when setting the water temperature. The most
energy efficient operation will result when the temperature
setting is the lowest value that satisfies the needs
consistent with the application.
Maximum water temperatures occur just after burner
has shut off. To find the temperature of the hot water
being delivered, turn on a hot water faucet, and place
a thermometer in the hot water stream, and read the
thermometer.
The following chart details the relationship of water
temperature and time to scald injury and may be used as a
guide in determining the safest water temperature for your
applications.
The temperature of the water in the heater can be regulated
by setting the temperature on the display (see "User
Interface" section). To comply with safety regulations the
water heater temperature was adjusted to lowest setting
before the water heater was shipped from the factory. The
illustration information on "User Interface" section shows
the display and how to adjust the water temperature.
DANGER:
Hotter water increases the potential for hot water SCALDS.
NOTICE:
Mixing valves are recommended for reducing point of
use water temperature by mixing hot and cold water in
branch water lines. It is recommended that a mixing valve
complying with the Standard for Temperature Actuated
Mixing Valves for Hot Water Distribution Systems, ASSE
1017 be installed. See Water Connections for more details.
For additional information, contact a licensed plumber or
the local plumbing authority.
