ᐅ F90 shaft

Created on: 9 Aug 2016 20:52

Good evening everyone,
could someone please explain the function of an F90 shaft in connection with a condensing boiler in a new building? Specifically, the exhaust gas discharge, intake air, etc.

Thank you very much and best regards
Roland

Hi Roland, it all comes together in one pipe (but separated from each other, inner pipe, outer pipe).

Hello Thorsten, it looks to me like a single pipe.
