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").
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 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-combusti-
ble 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" must extend a minimum of 18".
