I need to run a network cable (copper wires = metal content) from the attic down into my office area, and the best place to do it would be in one of the walls that encloses the chimney. The chimney has both a firepalce, and the flue for the oil furnace.
I'm not sure if there is any code restriction to avoid running wires in a wall surrounding a chimney, and if we ever use the fireplace I suppose the back of the brickwork could get toasty enough to melt the insulation on the wires.
Is this a dumb thing to try to do? Is it an illegal thing to try to do?
