2200 Insert Installation and Operation Manual
8.3 COMPLIANCE OF A COMBUSTIBLE MANTEL SHELF
To ensure compliance of an existing mantel shelf or to install a combustible mantel shelf, refer to
table and figure below. For example, a mantel shelf with a 9.5'' depth (241 mm) ((X) value) must
be installed at least 22" (559 mm) ((I) value) above the top of the insert (see figure below).
Different mantel shelf dimensions are listed in the following table. However, no combustible
mantel shelf can be installed at less than 22" (559 mm) above the top of the insert. If the depth of
the mantel shelf is not listed in the table below, add 12.5" (318 mm) to the depth of your mantel
shelf to obtain the safe positioning of your mantel shelf. For example, for a 11" (279 mm) mantel
shelf, the safe positioning would be 23.5" (597 mm) above the top of the insert (12.5" (318 mm) +
11" (279 mm)).
