DANGER
WARNING
• Water temperatures over 52 °C (125 °F) can cause severe burns instantly or
death from scalding. The water temperature is set at 49 °C (120 °F) from the
factory to minimize any scalding risk. Before bathing or showering always
check the water temperature.
• Do not store or use gasoline or other flammables, vapors, or liquids in the
vicinity of this appliance.
• Do not reverse the water and/or gas connections as this will damage the gas
valves and can cause severe injury or death. Follow the diagram on p. 22
when installing your water heater.
• Do not use this appliance if any part has been in contact with or been
immersed in water. Immediately call a licensed plumber, a licensed gas
fitter, or a professional service technician to inspect and/or service the unit if
necessary.
• Do not disconnect the electrical supply if the ambient temperature will drop
below freezing. The Freeze Protection System only works if the unit has
electrical power. The warranty will not be covered if the heat exchanger
is damaged due to freezing. Refer to the section on the Freeze Protection
System on p. 40 for more information.
