Navien NP-180 Service Manual page 18

GAS TYPE and AC VOLTAGE
Navien units come from the factory configured for use with either Liquid Propane
(LP) or Natural Gas (NG).
Before starting the servicing, check the rating plate located on the side of the
Water Heater to ensure the unit matches gas type, gas pressure, water pressure
and electrical supply.
Be sure the gas type and electricity voltage match the Rating Plate.
• Use only the same gas type indicated on the rating plate of the Navien Water
Heater. Using different gas type will cause abnormal combustion and water
heater malfunction.
•
Be sure to use 120 VAD, 60 Hz, minimum 2 A current. Using abnormally high
or low AC voltage may cause abnormal operation, and may reduce the life
expectancy of this product.
If the unit does not match requirements, do not service, please contact
Navien immediately.
GAS CONVERSION
Conversion of this unit from natural gas to propane or vice versa cannot be done
in the field. Please reconfirm gas type on the rating plate (left side of unit) before
servicing. DO NOT attempt any field conversion, this will result in dangerous
operating conditions and will void all warranty.
Navien America Inc. is not liable for any property damage and/of personal
injury resulting from unauthorized conversions.
