Rating Plate - Navien NPE-180A2 Installation Manual

2.7 Rating Plate

Water Heaters come from the factory configured for use with Natural Gas (NG). 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 is
required, the included Propane conversion kit 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 and water heater malfunction.
Using abnormally high or low AC voltage may cause abnormal operation, and may reduce the life
●
expectancy of this product.
