3.4.2 Hearth Extension Requirements
The BIS ULTRA may be installed directly on a combustible floor, however the hearth
extension in front of the fireplace must be made of non combustible material and
incorporate _" air space to the wood floor (fig.5). To maintain that _" air space, you
must use non-combustible material to frame the hearth extension support and create the
air gap or use a sheet metal part (7B30ZM) manufactured by Security Chimneys
International. It must be covered with tile, marble, stone or other non-combustible
material.
If the fireplace is raised a minimum of 4" from the floor, then the air space is not
necessary but a piece of sheet metal must be fabricated to join the bottom of the fireplace
to the hearth extension (fig. 6).
