Mantel Clearances - Desa CCL3924NR Owner's Operation And Installation Manual

If Using Mantel
You must have noncombustible material(s)
above the fireplace opening. Noncombustible
materials (such as slate, marble, tile, etc.)
must be at least 1/2" thick. With sheet metal,
you must have noncombustible material be-
hind it. Noncombustible material must extend
at least 8" up. If noncombustible material is
less than 12", you must install the fireplace
hood accessory. Even if noncombustible
material is more than 12", you may need the
hood accessory to deflect heat away from
your mantel shelf. See Figure 5, 6 and 7 for
minimum clearances.
IMPORTANT: If you cannot meet these mini-
mum clearances, you must operate heater
with chimney flue damper open. Go to Install-
ing Damper Clamp Accessory for Vented
