Clearances
If Not Using Mantel
Note: If using a mantel proceed to If Using
Mantel. If not using a mantel, follow these
instructions
.
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 behind
it. Noncombustible material must extend at
least 8" up (for all models). If noncombustible
material is less than 12", you must install
the fireplace hood accessory (24" and 30"
Models Only). See Figure 5 for minimum
clearances.
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 (for all models). If noncombus-
tible material is less than 12", you must install
the fireplace hood accessory (24" and 30"
Models Only). Even if noncombustible mate-
rial is more than 12", you may need the hood
accessory to deflect heat away from your
mantel shelf. See Figure 5 and Figures 6 and
7, page 11, for minimum clearances.
IMPORTANT: If you cannot meet these mini-
mum clearances, you must operate heater
with chimney flue damper open. Go to
