GENERAL SAFETY

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 rec-
ommended initial setting for the temperature 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 elderly are at highest risk of being scalded.

Feel water before bathing or showering.

Temperature limiting valves are available.

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 and place a thermometer in the hot water
stream and read the thermometer.

NOTE:

When this water heater is supplying general

purpose hot water for use by individuals, a thermo-
statically 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. 

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.

Time/Temperature
Relationships in Scalds

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.
