3.3.2 HEARTH EXTENSION

EN
An acceptable 61½" (1562mm) x 20" (508mm) non-combustible SEE
(ie: brick, stone or ceramic tile) hearth extension must be installed. HEARTH
Hearth must extend 20" (508mm) in front of the faceplate when EXAMPLES
it is not elevated (see local building codes). Hearth must extend
a minimum of 12" (305mm) to both sides of the appliance [70"
(1778mm)].
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 fl oor, 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" (457mm).
