I know it's hard to see, but is this sectioned liner in upside down? You can see the end ridges on the connection pipe, right?

I'm talking about the "background" connection, not the one the camera focused on.

Not really. In a B-vent, the upper liner sleeves inside the lower, just like on a woodstove. If you're using single-wall vent pipe, you should be sleeving it the same way, but few do. The result is condensation that runs outside the joints.
