Check against the official notice below — it lists the full affected range.
Navien is recalling specific models of tankless water heaters and combination boilers (model numbers NPE-180A, NPE-180S, and NCB-180E) manufactured between July 9, 2018 and October 14, 2018 that have been converted from natural gas to propane gas.

If you own one of the affected units, you should immediately stop using the water heater or boiler if it is operating on propane gas. You should contact Navien for a free replacement conversion kit. If you must continue using the unit while waiting for repair, you should install a working carbon monoxide alarm outside of sleeping areas in your home.
