MANTEL
A masonry or other non-combustible mantle may be placed
directly above the top louvers. If a wood or other com-
bustible mantle is desired, then it must be at least 10 1/2
inches above the top louver opening (see Figures 16 and
17). No combustible material is to be put under mantle.
HEARTH EXTENSION
The area immediately in front of the fireplace must be pro-
tected by a non-combustible material such as brick, tile,
stone, or slate. The protection must extend at least 16" in
front and 8" on both sides of the fireplace opening (see
Figure 16). There is no minimum thickness required for the
hearth extension.
