GAS TYPE and AC VOLTAGE<br />
WARNING<br />
<strong>Navien</strong> units come from the factory configured for use with either Liquid Propane<br />
(LP) or Natural <strong>Gas</strong> (NG).<br />
Before starting the servicing, check the rating plate located on the side of the<br />
<strong>Water</strong> <strong>Heater</strong> to ensure the unit matches gas type, gas pressure, water pressure<br />
and electrical supply.<br />
Be sure the gas type and electricity voltage match the Rating Plate.<br />
• Use only the same gas type indicated on the rating plate of the <strong>Navien</strong> <strong>Water</strong><br />
<strong>Heater</strong>. Using different gas type will cause abnormal combustion and water<br />
heater malfunction.<br />
• Be sure to use 120 VAD, 60 Hz, minimum 2 A current. Using abnormally high<br />
or low AC voltage may cause abnormal operation, and may reduce the life<br />
expectancy of this product.<br />
If the unit does not match requirements, do not service, please contact<br />
<strong>Navien</strong> immediately.<br />

GAS CONVERSION<br />
Conversion of this unit from natural gas to propane or vice versa cannot be done<br />
in the field. Please reconfirm gas type on the rating plate (left side of unit) before<br />
servicing. DO NOT attempt any field conversion, this will result in dangerous<br />
operating conditions and will void all warranty.<br />
