Rating Plate - Navien NPN Installation & Operation Manual

2.7 Rating Plate

Water Heaters come from the factory configured for use with Natural Gas (NG) or Propane Gas(LP). Before
starting the installation, check the rating plate located on the side of the water heater to ensure that the water
heater matches the gas type, gas pressure, water pressure, and electrical supply available in the installation
location. If the water heater does not match each of these ratings, do not install the water heater. If
conversion to Propane Gas or Natural Gas is required, the Gas conversion kit (optional) must be used.
WARNING
Be sure the gas type and electricity voltage match the rating plate. Using a different gas type will cause
●
abnormal combustion, excessive carbon monoxide emissions and water heater malfunction.
Using abnormally high or low AC voltage may cause abnormal operation, and may reduce the life
●
expectancy of this product.
