I have a new Navian model NPE-18082. That model is not listed anywhere in the manual with the unit. I need it to be for propane. How do I confirm it is propane. It clearly shows it is NG

To confirm if the Navien model NPE-180A2 is set up for propane instead of natural gas, check for the following:
1. Conversion Sticker: Look for a sticker on the side of the unit (the side with the serial and model number). It should be filled out with the conversion date, kit number, and installer information.
2. Propane Orifice Installed: Confirm that the propane orifice has been installed in place of the natural gas orifice.
3. O-rings and Screws: Ensure that the correct O-rings (including the figure-eight O-ring) and screws are seated properly after conversion.
If these elements are present and correctly installed, the unit has been converted to propane.
