Anybody with experience of placing their screens above a working coal fire? My normal size TV is placed in the corner of the room but feel my new plasma would be wasted in the same corner. The only wall position suitable for placing the plasma on is directly above my coal fire. Stuck a thermometer on the mantle piece last night and the max temp reading was 75 Deg (old system). Would this be too hot for it? What would the optimum height for placing a screen when the sitting positions are approx 6-8 ft away? Thanks for the help.
