Do it properly!! I've seen some very scary chimney set-ups, that worked. People in this one particular town are dirt poor. Not even going to describe any chimney set-ups. The residents lived in old run down houses, campers, busses, sheds, tar-paper shacks, you name it. Very poor........The only building in the whole town that looked great, was the high school. All marble front, well manicured landscaping, etc.. A school you would see in an upper middle class neighborhood. It looked like a palace. It wasn't long after doing some work in this town, the same town made the local news at my place (1-1/2 hours away). Said school wanted to raise taxes.
