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
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.
NOTE: When this water heater is supplying general purpose hot water for use by individuals, a thermostatically 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 and place a thermometer in the hot water stream and read the thermometer.
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.
