If Using Mantel
You must have noncombustible material(s)
above the fireplace opening. Noncombus-
*
tible materials (such as slate, marble, tile,
etc.) must be at least 1/2" thick. With sheet
metal, you must have noncombustible ma-
terial 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). 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 and Figures
6 and 7, page 11, for minimum clearances.

MANTEL CLEARANCES

In addition to meeting noncombustible mate-
rial clearances, you must also meet required
clearances between fireplace opening and
mantel shelf. If you do not meet the clearances
listed below, you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between
mantel shelf and top of fireplace opening, a
hood is not required (see Figure 6).
