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 appliance (61 ½").
The hearth must extend a minimum 20" in front of the appliance although if
raised a minimum of 6 1/2" the 20" may be reduced to a minimum of 18".
The hearth must extend a minimum of 6" to both sides of the appliance (61 ½").
The hearth must be a minimum of 1" thick cement board (or equivalent) plus ¼"
ceramic tile.
Ensure that the gap between the appliance and a non-combustible
hearth extension is sealed with sand/cement grout or covered with
an ember strip (or both) to prevent sparks and embers from falling
into this area.
Raised hearths must be constructed of non-combustible 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.
A raised hearth together with the appliance built on a raised platform is recommended for easier wood loading and
fi re viewing.
EMBER STRIP
(See “HEARTH
EXAMPLES” Section)
HEARTH EXTENSIONS ARE TO BE INSTALLED ONLY AS DESCRIBED TO PREVENT HIGH
TEMPERATURES FROM OCCURRING ON CONCEALED COMBUSTIBLE MATERIALS. HEARTH
EMBER STRIPS PREVENT BURNING OR HOT PARTICLES FROM INADVERTENTLY FALLING
DIRECTLY ON COMBUSTIBLE SURFACES IN THE EVENT THE BUILDING SHOULD SETTLE AND
DISTURB THE ORIGINAL CONSTRUCTION.
