An acceptable 70" (177.8cm) x 20" (50.8cm) non-combustible (ie:
brick, stone or ceramic tile) hearth extension must be installed.
Hearth must extend 20" (50.8cm) in front of the faceplate. Hearth
must extend a minimum of 12" (30.5cm) to both sides of the
appliance [70" (177.8cm)]. See local building codes for more detailed
dimensions.
Hearth must be a minimum of 1" (25mm) thick cement board (or
equivalent) plus ¼" (6.4mm) ceramic tile.
Ensure that the gap between the appliance 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.
HEARTH EXTENSION
Elevated hearths must be constructed of noncombustible materials
such as cement blocks or bricks.
While the appliance can be installed directly on the floor (using the
ember strip), a non-combustible hearth extension is required in front
of the appliance, that must not be built higher than the bottom of the
appliance faceplate. It may therefore be advisable to build the appliance on a raised platform.
Hearths raised minimum 6 ½" (165mm) must extend a minimum of 18" (45.7cm).

EXAMPLES
A raised hearth together with the appliance built on a raised platform is recommended for easier wood loading
and fire viewing.
