I have a buck model 21 stove and was told by a chimney cleaning company that it was very unsafe to use due to fire brick missing from the top. The inspector said i was lucky to not have blown up my home. Anyway, I contacted buck and they don’t have drawings or how the brick is supposed to be laid out. I was wondering if anyone has a buck 21 that can show me a picture of how the brick is supposed to be laid out on the top, thanks in advance, pic attached.
