Rich, thanks for sharing the 765's flue tube installation. The pictures show a very high standard of workmanship. The copper ferrule is interesting. It has a higher thermal expansion coefficient than the steel sheet and flue tubes, so it should make a good water seal.

Are the flue tubes installed in the front sheet with copper ferrules, rolled ends and seal welding?
