Thanks for the video. I apologize if my terminology is wrong because I know little about this stuff BUT…I have an issue with reattaching the stove to the wall pipe/thimble…I see the wall piece has an inner pipe with a surrounding outer pipe that the stove exhaust pipe is supposed to fit into. I can’t get the stove to fit into this. I think parts might have some bending on the wall device. What are my options for fixing this? (If this makes any sense at all). Thank you!
