Several weeks ago, a woman I work with told me that she had a chimney fire at her house over the weekend. Thankfully, the house didn't catch fire and everyone was safe. The fire department came, put out the fire and she was told not to burn her wood stove or furnace, that was sharing the same flue. I knew that the stove was in the basement and she has a fireplace on the first floor. She wouldn't give me many detals initially, but I was able to get her describe her set-up. Her husband put a woodstove in the basement and piped it into the cleanout of the fireplace. He removed the ash hinge thing in the fireplace, closed the glass doors and let the smoke rise from the cleanout, up through the fireplace and up the chimney. They have been burning like this for 10 years, with 3 children in the house! Apperently, her father place a pipe from the cleanout, up through the fireplace and into the chimney, thinking this would make things safer, but her husband didn't like the look of the pipe in the fireplace so he took it out. Thank God they're all safe.
