An acceptable 61½" x 20" non-combustible (ie: brick, stone
or ceramic tile) hearth extension must be installed.
Hearth must extend 20" in front of the faceplate when it is
not elevated (see local building codes).
Hearth must extend a minimum of 6" to both sides of the
unit (61 ½").
Hearth must be a minimum of 1" thick cement board (or
equivalent) plus ¼" ceramic tile.
Ensure that the gap
between the
fireplace and a
combustible hearth
extension is sealed
with sand/cement
grout or covered
with a metal strip (or
both) to prevent
sparks and embers
from falling into this
area.

While the fireplace can be installed directly on the floor, a
non-combustible hearth extension is required in front of
the fireplace, that must not be built higher than the bottom
of the fireplace faceplate. It may therefore be advisable to
build the fireplace on a raised platform.
Hearths raised minimum 6 ½" must extend a minimum of
18".
A raised hearth together with the fireplace built on a raised
platform is recommended for easier wood loading and fire
viewing.

examples.
