3.5.1.1 TV Recess Construction
WARNING: All clearances to venting must be maintained.
Mounting a television above a fireplace is a common practice. Mantel
depth, ceiling heights, and wall and mantel construction material all
affect television surface temperatures. Most television manufacturers
specify in their instructions that a television should not be installed
on, near, or above a heat source.
Television location rests solely on the homeowner. It is the home
owner's responsibility that the preferred TV mounting and mantel
design will not exceed the listed maximum operation temperature of
their electronic goods.
The drawing below shows the minimum dimensions for standard
installation of the fireplace. Anything above the minimum enclosure
height of 48" (1219mm) can be capped off or recessed for standard
installation.
