Somebody gave me this stove. Has anybody seen one like this before? It comes apart in an upper and lower half. I sanded the rust off and painted it with high temperature paint. I lit a fire in it to cure the paint job, and I noticed that smoke comes out of the seam between the two halves. I want to get it into shape to use as an emergency heat source in a home. Would flue tape be sufficient to seal this thing up, or would using this indoors be a bad idea?
