Fireplace
This fireplace changed from the original design slightly so I am not 100% sure but I am going to say it is slightly under 24" off the floor and there is about 3" of stone with a stone mantle of 3" high by 3" deep before the TV. Typically you need to have something projecting out about 3-5" before the tv to direct the heat of the fireplace out. This all depends on the BTU's of your fireplace and you should check with your fireplace specs before mounting any tv.
