Floor Protection requirements;
raised hearth 6" (152 mm) or higher-
The depth of the masonry hearth must measure a minimum
of 12.5 inches (318 mm) from the face of the fireplace
opening, to support the insert body. Depending on the
overall depth of the hearth, additional floor protection may
be necessary. If the depth of the hearth measures 25.5
inches (648 mm) or more, from the fireplace facing, no
additional floor protection is needed. If the hearth depth is
less than 25.5 inches (648 mm), floor protection must be
installed.
Floor protection in front of the raised hearth must be a
minimum 3/8" (9.5 mm) of 0.84k material. An R value of
0.45 or higher is also acceptable. The standards call for
floor protection to extend a minimum of 18 inches (457 mm)
in front of the appliance door opening, and 8 inches (200
mm) to each side.
