Question: I do hope you can give me some insight. My system will be eight years old this November. March of this year I had a chimney fire. Now my question is do I need to replace my stove pipe. It is very clean as you might guess from the fire. I cleaned the flue every year but I was burning a lot of green wood. Answer: If it is solid and in good shape, you needn't replace it. One way of checking is that there should be no rust or soft spots that you could poke through with a sharp nail or penknife blade. I'm speaking of interior black pipe. If you have a metal insulated chimney, the inside should be inspected for signs of wear and distortion.
