Escape 1800 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 8'' depth (203 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 14" (356
mm) to the depth of your mantel shelf to obtain the safe positioning of your mantel shelf.
For example, for a 9" (229 mm) mantel shelf, the safe positioning would be 23" (584 mm)
above the top of the insert (14" (356 mm) + 9" (229 mm)).
