Households withsmall children, disabled, orelderly persons mayrequire a 120°F or lowerthermostat setting toprevent contact withHOT water.Water Temperature SettingThe temperature of the water in thewater heater can be regulated by settingthe temperature dial of the adjustablesurface mounted thermostat(s) locatedbehind the jacket access panel(s).Dual element heaters have twothermostats.Safety and energy conservation arefactors to be considered when selectingthe water temperature setting of thewater heater’s thermostat(s). The lowerthe temperature setting, the greater thesavings in energy and operating costs.To comply with safety regulations thethermostat(s) are factory set at 120°For less where local codes require. This isthe recommended starting point.Water temperatures above 125°Fcan cause severe burns or death fromscalding. Be sure to read and follow thewarnings outlined in this manual and onthe label on the water heater. This labelis located on the water heater near thethermostat access panel.Mixing valves are available for reducingpoint of use water temperature by mixinghot and cold water in branch water lines.Contact a licensed plumber or the localplumbing authority for furtherinformation.The chart below may be used as a guidein determining the proper watertemperature for your home.Reset buttonThermostatprotectivecoverThermostatdial pointerSafety Instructions Installation Instructions Operating Instructions Care and Cleaning Troubleshooting Tips Customer Service
