Came across a seriously dangerous installation , yesterday. It was a Stanley erin boiler stove, the soul source of heating in this 2 storey semi D house. The chimney breast was constructed with timber frame. Picture the lintel in timber just 125mm above stove. When you look in to ope created you could see the floorbooards upstairs. Off the top of stove, fitted directly into collar was a flexi flue. Vertical for about 150mm then bent to form a 60 degree bend approx, taking it into existing chimney cavity. On the direct opposite wall to the flexi entry point was a soot door.
