stone or ceramic tile) hearth extension must be installed. Hearth must EXAMPLES
extend 20" (508mm) in front of the faceplate when it is not elevated (see
local building codes). Hearth must extend a minimum of 6" (152mm) to
both sides of the appliance [61½" (1562mm)].
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, 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).
