EXAMPLES

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 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).
