Hot Water Supply 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 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.
