For those folks planning to place a TV above a Gas Fireplace ( an extreme heat source) The Valor Heat Shift is the best option for solving the TV or heat
sensitive objects above a fireplace. Some commenters are concerned
with the 60% of the heat being emitted from the grille near the ceiling,
But a circulating fan in the fireplace only pushes the heated air out
about 2 feet or less and guess what, it rises right up to the ceiling
and creates a convection current in the room. Valor created this system
to mitigate heat above the fireplace opening, but in the process they
created the super high efficiency fan that is not a fan. Unlike a fan it
is totally silent, Unlike a fan it works every time the fireplace is
on, Unlike a fan it works when the power is out as it does not use
electricity, Unlike a fan it never wears out or breaks down and needs to
be replaced, and it moves more air than any fan. As an extra bonus it
cools the wall so much that combustible materials can now be installed
on the wall right to the fireplace opening as well as combustible
mantles at a 1 to 1 ratio above the opening. The use of a ceiling fan
will do more to even the room temperature than any circulating fan in
the fireplace.

here they just have a small/slimmer mantle - could be an option
