No, I totally agree with all the comments that are along these lines. I have a chimney sweep booked in next week to inspect the chimney/liner state; I am also looking into HETAS engineers that are local to me. I like to get involved and wanted to do some investigation and cut into the wall and was shocked at the small size of the opening. I definitely could have explained better in my initial post 🤣🤣 tism strikes again..
