LCD/Plasma issues with mounting over fireplace??  

So I would assume that your fireplace has a fan that blows the heat away from the fireplace. I would suggest you by a thermometer and hang it in the spot where the plasma will be and turn on the fireplace and see what temp it reads. Heat rises, and the plasma probably uses fans too remove heat from the set, since the fans would be drawing air in through the frame off the set and out the top, they would be drawing the hot air coming off the fireplace. You probably get where I'm coming from.

Most seem to think that if you have a mantle you're OK. I wouldn' think a gas burning fireplace would put out extreme heat.

I dont have a fireplace setup but was curious, so I googled and found this



Will the heat from the fireplace harm the plasma TV?

There are a few precautions to take before implementing this TV application. First, take a thermometer and tape it to the wall above the mantel (where the plasma TV will be placed). Then and build a fire, let it roar while. Check the thermometer. If the temperature is above 90 degrees then the area is receiving too much heat - either escaping from the front of the fireplace and rising up the face, or radiating through the chimney to warm the outside wall. In this situation it would not be advisable to run the plasma for a long period of time while its environment is hot. Though the Plasma TV has its own cooling system, the surrounding heat will force the Plasma TV to work harder to cool itself, thus shortening the life of the unit over time. The Plasma TV may still be run for short periods without harming the unit even with the environment heat at 90 degrees or above.
