MANTEL
Masonry and other non-combustible mantels (shelf and posts) can be
placed anywhere around the fireplace facing. If the non-combustible
mantel is located between the top of the fireplace facing and the
specified height for a combustible mantel, then the wall portion between
the top of the fireplace facing and the mantel must be covered in non-
combustible material. If the non-combustible mantel is located at the
same height allowed for a combustible mantel, or higher, then no special
wall covering is required below the mantel.
If the combustible mantel shelf has a cross-section with variable depth,
it has to be installed so that its widest part is not installed lower than the
corresponding minimum installation height while making sure that the
lowest point of the mantel is not installed lower the minimum installation
height corresponding to its
depth (Table 2). Mantel depth is always
measured from the face of the fireplace (see Figure 11). This is
regardless of the depth of materials used for finishing the facing.
Vertical mantel posts are permitted on either the side of the fireplace
facing. If they made from combustible materials, the mantel posts require
the clearances specified in Table 3.
