There have been several recent threads on this and I thought I understood it until I went to the Judging Retreat in Dallas. There was a very nice Top Flight 62 used in the class that had the foam gasket outside the firewall (between the firewall and the fiberglass duct with the flapper valve in it). I would appreciate someone clarifying the specific order of the inner box, the sheet metal plate, the foam gasket, the firewall and the outer duct.
Thank you for your patience
