Have a navien Ncb-240e. Installed 2 years ago by professional company. Had multiple issues with install but finally got it working correctly after about a week. Pump went out 18 months later,which they said it shouldn't have but it was covered under warranty, no big deal. In recent research on maintenance, recirculation etc. I came to the realization it appears they have no air intake installed. The exhaust output on the right side runs straight up to a boot in the roof, however, the air intake on the left has no pipe and appears to be capped. Is there a possibility it doesn't need to be a piped through the roof and takes in air from the garage,or is this a major error in installation?
Thank you for your time
