    Yeah, Naiven may cover some warranty but they seem to be having issues

    I know the cause of the problem.  

    Navien makes a low quality product.

    I would like to know the Serial number, LP or NG, see pictures of the install along with pictures of the vent terminations. My experience shows Navien as a excellent product with many messed up installations that lead to pre mature failures. Many LP conversions that are not done correctly resulting in eventual overheating the and the issue being experienced here. No one make bad equipment but we do experience bad installs.

    The exhaust pipe is cockeyed and maybe leaking and for no good reason
