Use non-combustible materials where indicated for the fireplace
installation. Non-combustible materials do not ignite or burn as a
result of using the fireplace. these include metal, brick, ceramic,
concrete, slate, glass, and plaster. Adhesives must be rated for

fireplace high temperature applications. Any mechanical fas
-
teners used to install materials must also be non-combustible,
including wall anchors and tile spacers. Materials that pass the
ASTM E-136 test (Standard Test Method for Behavior of Materi-
als in a Vertical Tube Furnace at 750C) are considered non-
combustible.
Do not allow combustible materials adjacent to or in contact with
the fireplace or venting. Combustible materials include wood,
compressed paper, plant fibers, or other materials that will burn.
These materials are considered combustible even when treated
with fire-retardant chemicals.
Television considerations
Installing a television above a fireplace has become a desirable
feature; however, the following information should be considered.
All fireplaces, whether decorative or heater rated create heat.
Most television manufacturers recommend not placing a televi-
sion near a heat source. Because there is a large variety of
television manufactures, styles and sizes, it is impractical to test
every potential installation. If you choose to install a television
above or near your fireplace, understand that Empire Comfort
Systems accepts no responsibility for this decision and any injury
or damage due to this application is the sole responsibility of
the owner. Additionally, it is highly recommended to turn off the
fireplace and let it cool down before servicing or using the opera
-
tional buttons located on the television. In all cases, the television
manufacturer’s instructions and warnings should be followed.
