That's a great question. According to the fireplace manufacture we are well above the min requirements for combustible materials. Keep in mind this is a direct vent fireplace, which are supper efficient units. We prefer to have a mantel to help shield rising heat, plus they look nice, but in this case, the client wanted a modern look without a mantel and there isn't another place for the TV in this particular living room for a 75" TV. That said, this fireplace unit has a blower which pushes the hot air out into the living space rather allow it to flow straight up into the TV. We've not heard an issue from the client about over heating the TV. I would read the fireplace manufacture recommendations about "combustible" clearances" before placing a TV above your fireplace. Lastly, you can add a short metal shield right above the fireplace to help direct the hot air flow away from the TV / wall. Hope this information is helpful! - Steve
