3.3.2 HEARTH EXTENSION

EN
EMBER STRIP
(Provided)
An acceptable 70" (177.8cm) x 20" (50.8cm) non-combustible (ie: SEE HEARTH
brick, stone or ceramic tile) hearth extension must be installed. EXAMPLES
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).
A raised hearth together with the appliance built on a raised platform is recommended for easier wood loading
and fire viewing.
