If not using a mantel, follow these instructions.
You must have noncombustible material(s) above
the replace opening. Noncombustible materials
(such as slate, marble, tile, etc.) must be at least
1/2" thick. With sheet metal, you must have non-
combustible material behind it. Noncombustible

If noncombustible material is less than 12", you
must install the replace hood accessory (24" and

If noncombustible material is less than 12", you
must install the replace hood accessory (24"

for minimum clearances.

MANTEL 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 listed below, 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, page 11).
If minimum clearances in Figure 6, page 11, 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.
