Hello, I am looking for some parts for my old time stove. There are one of these holes on top of the stove, and one on the back. They are about 8 3/4 inches across. I assume the stove needs 8 inch stove pipe. My stove looks like this: Here is a pictures of the actual hole: I assume I can just block one of the holes off. And the other needs some sort of adapter to attach the pipe. What would this be called? Can I order one somewhere? thanks for any help. I'm new to this wood stove thing.
