Power Vent Flue Deposits

[tbaughman1 (Troy Baughman)]

Any ideas what would cause these deposits around the flue on this power vent?

Welcome to our forum, Troy!..Enjoy!

P.S. It almost looks like they trie to seal the joint.

Thank you. It is more of a scaling calcium type depost.

Well if that’s the case, then moisture likely is involved. How the moisture is getting there is the dilemma. Could be a venting issue. Was everything else kosher with the install?
