Ok looking at the plans its not clear what size tubing is used for the pitot tube and what material to use. What is the accepted material and size?
Second, what is the ceiling flange made of. I'm talking about the type that is a continuous flange that goes around the entire fire wall. I'm thinking a 1"x1" aluminum angle. But how thin can I go? .040"? Or thinner? Thank in advance. Phill Hill Collinsville, IL
