    I project my movies onto a large wall at the end of my living room. I have just bought a woodburning stove which I intend to place in the centre of this wall. The bottom of the current picture is about 18" above the top of the stove. Now the problem.

    UK building regs state that I must have a 600mm vertical flue pipe from the top of my burner before a bend. I want to go 45 degrees out through the end wall and then up outside the house. This means that the flue will be in the middle of my movie! Ideally I want to go up about 200mm and then 45 degrees out through the wall.

    Anyone know why I shouldn't do my preffered option? I can't see why I would have any problems with draw/ performance like this. Would I invalidate my insurance by defying building regs?

    The other option is to build a fake chimney into the room and run the flue inside that. The problem is that it's a barn conversion and has 'character' so this might be difficult to integrate well. Also, my current picture is about 7' wide so it would have to be built that wide.

    Any ideas? I like the convenience of profecting straight onto the wall.

    !!!Note might be talking a load of rubbish!!!!!

    i think its to do with heat. I.e. if you put the bend to close to the burner the top of the 45 degree bend will get to hot. But if it has a straight pipe it gets to cool a bit. Before it gets to the first bend. Just my idea, But I could be wrong.

    OK. I have a stove which has a 800mm flue rise to before it hits the fire board and goes up into the stone chimney. However, approx 600mm up from the actual stove, the fireplace mantle starts, therefore there is approx 200mm inside the fireplace which is hidden from view because the mantle drops below this. This has given me an idea. Couldn't you build the fireplace opening up to 600mm above the stove but behind the 1st layer of brick on the outside that you look at? I hope that makes sense, this then gives you a 600mm rise 'inside' the fireplace before the flue would bend, but the outside wall drops in front of this to allow you to retain a greater surface area on which to project an image.

    Hi. Are you sure about the building regs? I've been looking at a similar flue-pipe problem and don't see anything about the pipe having to be a vertical 600ml. Some stoves have a horizontal pipe at the back which can be up to 150ml. My understanding is that the pipe can be no more than 45 degrees from the vertical. Are you confusing with the exterior flue (ie chimney) having to be at least a vertical 600ml from the ridge line? If you are right I would be grateful if you could let me know the building reg. reference
