You must have noncombustible material(s)
above the replace 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 replace
hood accessory. Even if noncombustible
material is more than 12", you may need the
hood accessory to deect 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 ue damper open. Go to Install-
ing Damper Clamp Accessory for Vented
Operation, page 12.
