unkle spike Posted January 24, 2010 Share Posted January 24, 2010 The "men's room" for my shop is out back. The other day I was out back and I noticed a rusted spot, which poked right through when I poked it with my finger..... I have an over head hood, with about a 3 foot horizontal leg, a 90 degree elbow and a 15 foot up leg, with a cap. The whole chimney is 12 inch heat and air duct. It has been up around 5 or 6 years. I bought a new elbow at Home Depot, which was $8.95 and when I pulled the old one out I found that the elbow was half full of soot that had settled in it. I scraped it all out and it really draws now. Quote Link to comment Share on other sites More sharing options...
