Combustion / Vent kit Furnace

This appears to be a combination combustion air / exhaust air vent kit for a goodman furnace. Am I being too picky because it appears to be installed upside down? I’m undecided…

Chris, the concentric termination appears fine to me. I’ve seen them installed all around the vent.


I did not see anywhere in the installation manual where it specified exhaust and combustible air orientation. Here is an example of a vertical installation as well.
