Ok got the blaze king princess insert and a 9x13 flue. I got the flex king pro from chimney liner depot. Well I got 3/4 way down and she bound up hard so we worked it back and forth till it went. Well I looked inside and the inside liner was starting to kink. So I talked to chimney liner depot and they told me to put a board in it and ovalize it so it don't kink. Anyone run into this issue?
