Basic Product Data2.6. General SafetyThis section applies to Hot Water Supply Boilers and HotWater Heaters ONLY.To meet commercial hot water use needs, the high limitsafety control on this water heater will shut off the maingas valve before the outlet temperature reaches 210°F(99°C). However, water temperatures over 125°F (52°C) cancause instant severe burns or death from scalds. Whensupplying general purpose hot water, the recommendedinitial setting for the temperature control is 125°F (52°C).For sanitary rinse applications where outlet temperaturesof 180°F (82°C) to 195°F (91°C) are required, a boiler isrequired because the 210°F (99°C) limit on water heaterswill NOT allow the heater to maintain these desiredsanitary rinse temperatures.Safety and energy conservation are factors to beconsidered when setting the water temperature on thethermostat. The most energy-efficient operation will resultwhen the temperature setting is the lowest that satisfiesthe needs of the application.Water temperature over 125°F (52°C) can cause instantsevere burns or death from scalds. Children, disabled andelderly are at highest risk of being scalded. See Table B.• 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 watertemperature is recommended to reduce the risk of scaldinjury. Contact a licensed plumber or the local plumbingauthority for further information.Maximum water temperatures occur just after the heater’sburner has shut off. To determine the water temperaturebeing delivered, turn on a hot water faucet and placea thermometer in the hot water stream and read thethermometer.AA CAUTION: Hotter water increases the risk of scalding!There is a hot water scald potential if the thermostat isset too high.Water temperature over 125°F cancause instant severe burns or deathfrom scalds.Children, disabled, and elderly areat 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 areavailable, see manual.Water Temp.
