The inner 2" vent pipe should at least be cemented where it attaches deep inside the main 4" pipe. The 2" pipe does not expand or grow as much as the 4" pipe. With the cap around the 2" end and against the 4" pipe the difference in expansion will have the 4" pushing against the cap and possibly pulling the inner 2" pipe out of that interior socket.

I believe the minimum distance between two pipes is 12 inches. Is there also a maximum? Maybe a distance at which the system is no longer considered a true "direct vent"? 5) Let's confirm the distance questions above and talk about how a Concentric vent conforms. Concentric air intakes are certainly less than 12" from the exhaust.
