Direct vent systems can utilize two separate pipes or a concentric pipe (pipe within a pipe). The two-pipe system uses one pipe to pull in outside air for combustion and another to release exhaust gases, creating a sealed system that is ideal for maintaining indoor air quality. Such a setup ensures combustion gases do not mix with indoor air ...

A concentric (or direct-vent, or two-pipe) system maintains indoor air quality by reducing drafts with one penetration, and allows for better humidity level control inside a dwelling. Concentric venting brings to the heating appliance outdoor air as combustion air through an air-tight, sealed system that is safe.

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.

A concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes.For example, when a 1″ pipe transitions into a 3/4″ pipe and the top or bottom of the pipe doesn't need to remain level.

Ran into a customer yesterday who had 2 baths (at opposite ends of the house) renovated and convectors installed on a 2-pipe system. All is quiet except for these two, which are quite loud with boiling water sounds. Seems to me that once the trap closes the only place for the condensate to go is down the supply, and this is causing the noise.
