WARNING: Setting the temperature selector to higher settings provides hotter water, which increases
the risk of scald injury. If this appliance is used to produce water that could scald if too hot, such as
domestic hot water use, reduce the water temperature setting and utilize a system or point-of-use
temperature limiting valve to obtain a water temperature of 120ºF or less. See the “IMPORTANT SAFETY
NOTE” concerning hot water temperatures located near the front of this manual.
WARNING: Should overheating occur or the gas supply fails to shut off, do not turn off or disconnect the
electrical supply to the appliance. Instead, shut off the gas supply by turning off the manual gas valve
external to the appliance. Turning off or disconnecting the electrical supply to the appliance during
these conditions could result in a fire, explosion or exposure to hazardous materials, causing property
damage, personal injury or loss of life.
