You must have noncombustible material(s) above
the replace opening. Noncombustible materials
(such as slate, marble, tile, etc.) must be at least
1/2 inch 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 replace hood accessory
(24" and 30" models only). Even if noncombus-
tible material is more than 12", you may need the
hood accessory to deect heat away from your
mantel shelf. See Figure 5 and 6 and Figure 7 on
page 11 for minimum clearances.
In addition to meeting noncombustible material
clearances, you must also meet required clearances
between replace opening and mantel shelf. If
you do not meet the clearances in Figure 6 you
will need a hood.
If you meet minimum clearance between mantel
shelf and top of replace opening, a hood is not
required (see Figure 6).
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 clearances shown in Figure 7,
page 11 when using hood.
