I would look at mounting the TV on the 9ft section to the left of the fireplace, but not flushmount. If you angled it using either one of those articulated arms(wall mount) or angle it on a stand, it would give you a better seating/HT angle for viewing/listening. Those stoves throw off LOTS of heat so be carefull how close you mount to it, I would NOT consider mounting above the fireplace under any circumstance, myself.

Half of communication is listening. You can't listen with your mouth.
