3. Carefully plan where you intend to install the water heater. Please ensure:
• Your water heater will have enough combustion air and proper ventilation.
• Locate your heater where water leakage will not damage surrounding areas. (Please refer to p. 8.)
4. Check the rating plate for the correct GAS TYPE, GAS PRESSURE, WATER PRESSURE and ELECTRIC RATING. If this
unit does not match your requirements, do not install and consult with the manufacturer. The water heater is
configured only for use with Natural Gas at the factory. If the appliance is used with propane gas, conversion to
propane gas with an included conversion kit (LP Conversion Kit: 100270585) is required. The conversion must
be done by a qualified service agent or a gas utility serviceman in accordance with this instruction and all codes
and requirements of the authority having jurisdiction. Failure to follow instructions could result in serious injury
or property damage. The agent performing this work assumes responsibility for this conversion. (Refer to the
gas conversion leaflet.)
5. If any problem should occur, turn off all hot water fixtures and turn off the gas. Then call a trained technician
or the Gas Company or the manufacturer.
• Water temperatures over 125 °F (52 °C) can cause severe burns instantly or death from
scalding. The water temperature is set at 120 °F (50 °C) 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 use this appliance if any part has been under water. Immediately contact a
qualified installer or service agency to replace a flooded water heater. Do not attempt
to repair the unit! It must be replaced!
• 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. For more
