To meet commercial water use needs, the thermostat on this water
heater is adjustable up to 180°F. However, water temperatures over
125°F. 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 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.
Maximum water temperatures occur just after burner has shut off.
To find hot water temperature being delivered, turn on a hot water
faucet and place a thermometer in the hot water stream and read
the thermometer.
General Safety Precautions
!
The following chart details the relationship of water temperature
and time with regard 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 dial on
front of the thermostat. To comply with safety regulations the
thermostat was set at its lowest setting before water heater was
shipped from the factory. The illustration below illustrates the ther-
mostat and how to adjust the water temperature.
Hotter water increases the Potential for Hot Water SCALDS.
NOTE: MIxing valves are available for reducing point of use water
temperature by mixing and cold water in branch water lines Con-
tact a licensed plumber or the local plumbing authority for further
information.
