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. Even if noncombustible material
is more than 12", you may need the hood ac-
cessory to deflect heat away from your mantel
shelf. See Figure 5 and 6 and Figure 7 on
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
in Figure 6 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).
Determining Minimum Mantel Clearance
When Using a Hood
If minimum clearances in Figure 6 are not
met, you must have a hood. When using a
hood there are still certain minimum mantel
clearances required. Follow minimum clear-
ances shown in Figure 7, page 11 when
using hood.
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above the
firebox may become hot to
the touch. If installed properly,
these temperatures meet the
requirement of the national
product standard. Follow all
(A)
minimum clearances shown in
this manual.
