DANGER
There is a Hot Water SCALD Potential if the
thermostat is set too high.
NOTE: When this water heater is supplying
general purpose hot water requirements for use by
individuals, a thermostatically controlled mixing
valve for reducing point of use water temperatures
is recommended to reduce the risk of scald injury.
Contact a licensed plumber or the local plumbing
authority for further information.
Maximum water temperatures occur just after burner has
shut off. To find temperature of the water being deliv-
ered, turn on a hot water faucet and place a thermome-
ter in the hot water stream and read the thermometer.
The following chart details the relationship of water tem-
perature and time with regard to scald injury and may be
used as a guide in determining the safest water temper-
ature for your applications.
The temperature of the water in the heater can be regu-
lated by setting the temperature on the electronic ther-
mostat. To comply with safety regulations, the thermostat
was set at its lowest setting before the water heater was
shipped from the factory. See the section titled SET
POINT ADJUSTMENT PROCEDURE to set the electron-
ic thermostat.

WARNING
LP appliances should not be installed below-grade
(for example, in a basement) if such installation is
prohibited by federal, state and/or local laws, rules,
regulations, or customs.
To meet commercial water use needs, the thermo-
stat on this water heater is adjustable up to 160°F
(71°C) (Booster models have a maximum setpoint
of 180°F
(
82°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 controls for supplying gen-
eral purpose hot water.
Safety and energy conservation are factors to be
considered when setting the water temperature
on the thermostat. The most energy efficient
operation will result when the temperature setting
is the lowest that satisfies the needs consistent
with the application.
