Example
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 behind it. Noncombus-
tible material must extend at least 8" up (for all models). 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 3 and Figures
4 and 5, Page 6
, for minimum clearances.
IMPORTANT
:
If you cannot meet these minimum clearances,
you must operate appliance with chimney flue damper open.
