The wall above the fireplace is where most living rooms want the TV. It is also the spot with the most ways to go wrong: heat, height, and a wall that is often brick, stone or a framed chase instead of plain drywall on studs. Here is how I check that wall before I drill, then the details that decide any clean TV install. This work is part of my TV mounting service.
Is it safe to mount a TV above a gas fireplace?
It can be, but the fireplace and the TV each get a say. Start with the fireplace. Valor, a gas fireplace maker, tells owners to read the installation manual before planning a mount. Every model lists its own clearances for combustible and heat-sensitive materials, and those numbers set what can go on the wall above it. I read the manual for your model before I plan anything. If you cannot find it, the model number is usually on a plate near the controls, and the maker's site often has the manual.
Then the TV. Samsung's own support page says it does not recommend mounting its TVs over a fireplace, and that its TVs should never go above 104°F (40°C). Its advice is to light the fire and check the temperature first. Other TV makers set their own limits, so check the manual for your set. I run the fire for a good while before I take that reading.
A mantel does help. Samsung suggests a mantel or a recessed TV to keep rising heat off the bottom of the set. Valor adds a caution, though: a mantel can deflect heat a little, but it is not a heat shield. Some gas fireplaces can be fitted with a system that sends the heat up through ducts in the wall instead of across it. Valor's HeatShift is one. That has to be planned when the fireplace goes in, since it lives in the framing behind the unit.
Every job I take gets a written scope before I start, so the price is agreed in advance and the list stays the list.

How high should a TV go above a fireplace?
As low as the fireplace clearances allow, and no lower. Valor says the centre of the screen should sit roughly at eye level when you are seated. Samsung makes the same point from the other side: a TV above a fireplace ends up well above eye level. So the clearance sets the floor, and comfort pulls the screen down toward it.
I will not give you a single height in inches, because it depends on the fireplace, the mantel, your couch and how far back you sit. What I do is mark the lowest spot the clearances allow, then check it from where you actually watch. A tilting mount helps a high screen by angling it down toward the couch. A pull-down mount can bring it lower still when you are watching, if the wall and the budget suit one.
What the wall above a fireplace is made of
Fireplace walls are rarely simple. Some are brick or stone, which needs masonry anchors rated for the load and a drill that suits the material. Some are a framed box around the fireplace, called a chase, with studs you can find and use. Some have a stone veneer over framing. I find out which one you have before quoting, because it changes the anchors, the time and the cable route.
Anchor into studs or solid masonry
On a framed wall, a TV mount should go into studs, usually two for a larger screen. Toggle bolts have their place, but a heavy mount belongs in framing. If your framing turns out to be steel, mounting a TV on steel studs covers the anchors and the limits. A stud finder gives a rough location. A small pilot hole confirms the stud is where the finder says before the mount goes up.
Dead level, checked twice
A slightly crooked TV may not bother you on day one. It will every time a straight line crosses the screen. I level the mount before any screws go in, then check the TV again once it is seated on the mount.
Hide the cables
Cables hanging down the wall undo a clean install. An in-wall cable kit runs HDMI and power behind the drywall to an outlet below. On a fireplace wall the route is harder, because brick, stone and a chase all get in the way. If there is no outlet near the TV spot, adding one is new wiring, and that goes to a licensed electrician.
Pick the mount for the room
Fixed mounts sit closest to the wall but cannot tilt away glare. Tilting mounts are the workhorse, and they matter most on a high wall. Articulating mounts pull out and swing for corners or rooms where the seats face different ways. I confirm which one fits your room before I recommend it.
Tight hardware that stays tight
Even a mount in solid framing depends on the right washers and fasteners. I use the hardware the mount calls for and snug it properly, so the screen does not start to droop a year later.
