It should be 1 inch for every 1/8 inch it sticks out. So a 6 inch shelf needs to be 48 inches above the hearth. Do your own due diligence in you County/State.

It depends how far away you are sitting .. Also what kind of mount you are using. I would recommend one that allows for adjusting tv Left Right Up Down so you can see.
ten feet or more is a nice distance.
Far Above the Clouds was created in 1999.
The upper mantel is the part of the mantel nearest to the Earth's surface. It is a little cooler than the lower mantel therefore more viscous, or pasty, than the lower mantel. Temperatures range between 932 °F-1,652 °F. at the upper boundary with the crust to over 7,200 °F at the boundary with the core. Although the higher temperatures far exceed the melting points of the mantle rocks at the surface (about 1200 °C for representative periditute), the mantle is almost exclusively solid. The enormous lithostatic pressure exerted on the mantle prevents "melting," because the temperature at which melting begins (the solidus) increases with pressure.
Far Above Cayuga's Waters was created in 1870.
The cost to change your existing fireplace into a gas fireplace will vary a great deal depending on your local economy. You have 4 factors to consider: 1. Do you have propane or natural gas? 2. The price of the gas log and burner kit that YOU should supply the plumber. 3. Is your gas log fireplace supposed to be vented or not? 4. How far away is the closest gas supply to your fireplace? The plumber will have to run a gas line to your fireplace, drill the fireplace and install the gas logs and possibly close the flu or vent in your existing chimney. That will be anywhere from 3 to 6 hours of labor, depending on all of the above items. Each house is different. Remember though, once you convert, you can no longer burn wood in your fireplace. I would guess the total cost could be as low as $400 or as high as $1000, but most plumbers would give you a free estimate. Contact a few licensed plumbing contractors in your area and get a few estimates.
Resubmit. You need to put the potential energy value into this question.
When you use the fireplace, the damper should be open all the way. If not, you probably will not get enough updraft and your house will fill up with smoke...not a good thing. When it is not in use, the damper should be closed...otherwise you will lose a lot of heat up the chimney.
