So last year I had a 25 ft stainless steel liner installed in my 7x11'' flue. Today as I was getting ready to sweep the chimney, I noticed that there is a pretty severe bend in the liner 4 or 5 ft from the top. I can see through the bend fairly easily so it is not that sharp. The bend appears to be rounded and not kinked. Is this going to cause me issues? I do realize that the liner was tight going in and there were some bends to get around. The clay liner was built wavy.
