Wondering if anyone can help me with a flue project. I just removed a brick hearth in my kitchen. It was in the way (the kitchen is very small), and the woodstove that had been sitting on it was never used...not to mention it was venting into a flue it shared with the furnace. I still use the furnace, so I just want to cap the horizontal pipe and build a new wall where the brick was.
The problem is the horizonal thimble that protrudes from my concrete chimney is too long. It sticks out several inches past where the new wall needs to go. Is it possible to cut the thimble shorter? I think it's clay, but I'm not sure. I'm afraid it might shatter when I try to cut it. And once it's cut to size, how can I safely cap it? Right now there's metal stove pipe inserted in the thimble, and the cap over the that pipe is taped on.
Any ideas? Thanks!
