Yes. You certainly can put a television above your fireplace. It’s not a problem and most of our customers do exactly this. Because the heater blows out from underneath the log set, and straight into the room, it will not interfere with your television in any way. Also the mantle is strong enough to hold the weight of even a very large television.
Of course it can also be mounted directly to a wall. Whichever way you see fit, a television above the fireplace is a great idea to enjoy your fireplace and a movie at the same time.
