I'm going to be getting a free standing wood burning stove fitted and did some measurements in the loft last night to see where the flue will go. The stove we've ordered has to be 200mm from the wall downstairs. With the flue running straight up and into the loft there will be a clearance of only 30mm to the closest joist. The minimum clearance allowed is 50mm. I can't move the stove back any closer to the wall and moving it forward another 600mm isn't an option either. With that in mind here are my questions...
1. Would it be safe for me to chisel 20mm into this joist, probably 200mm in length and add reinforcement to the other side of the joist?
2. If the answer to 1 is yes, how should I reinforce it? Should I use a length of joist on the other side of the joist I am cutting out of? If so how long should the reinforcement be and how should I fix it to the existing joist?
The only other option I can think of is to have the flue come out of the stove at a slight angle so that it brings the flow back 50mm or so. However I expect that having a twin flue part made up to go up, back at an angle and then straight up again would be rather expensive.
