To meet commercial hot water use needs, the high limit
safety control on this water heater is adjustable up to
210°F. However, water temperatures over 125°F can
cause instant severe burns or death from scalds. When
supplying general purpose hot water, the recommended
initial setting for the control is 125°F.
Safety and energy conservation are factors to be con-
sidered 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 of the application.
Water temperature over 125°F can cause instant severe
burns or death from scalds. Children, disabled and eld-
erly are at highest risk of being scalded.
Feel water before bathing or showering.
Temperature limiting valves are available.
NOTE: When this water heater is supplying general
purpose hot water for use by individuals, a thermostati-
cally controlled mixing valve for reducing point of use
water temperature 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 the
heater’s burner has shut off. To determine the water
temperature being delivered, turn on a hot water faucet,
place a thermometer in the hot water stream and read
the thermometer.
This section applies to Hot Water Supply Boilers and
Hot Water Heaters ONLY. For sanitary rinse applica-
tions where outlet temperatures of 180°F to 195°F are
required, a boiler is recommended since the 210°F limit
on water heaters will NOT allow the heater to maintain
these desired sanitary rinse temperatures.
Water temperature over 125°F can
cause instant severe burns or death
from scalds.
Children, disabled, and elderly are
at highest risk of being scalded.
See instruction manual before set-
ting temperature at water heater.
Feel water before bathing or show-
ering.
Temperature limiting valves are
available, see manual.
