Hello, I have a Breckwell P 2000 pellet stove and I am attempting a 4in flexible chimney liner this weekend. I am in good shape for most of the install, but I need to increase/transition the pipe from 3in at the stove connection piece to the 4in liner that I run up the chimney, see photos.

What transition adapter do I need and how is it secured in place. I ordered a “duralock” type 3in to 4in adapter from Amazon and it does not appear to be correct.

Any feedback or suggestions on how to make this transition and connection is appreciated
