MINIMUM NONCOMBUSTIBLE
MATERIAL CLEARANCES
If Not Using Mantel
Note: If using a mantel proceed to If Using
Mantel. If not using a mantel, follow the infor-
mation on this page.
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", 30" and
36" 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", 30" and 36"
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 Figures 5 and 6 and Figure
7, page 9, 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).
