TYPICAL FRAMING - RAISED HEARTH:
Warning: Failure to follow these guidelines may result in elevated operating temperatures, an inability to remove or install the door.
A non-combustible Hearth Insulation Board is required to be installed between any non-combustible hearth covering and any combustible floor-
ing beneath.
The design of the unit is such that the fireplace must
be raised by the same distance as any additional
hearth covering or riser that are added in front of
the fireplace.
Figure 14 shows a raised hearth made of a wooden
construction hearth riser (B), covered with the insu-
lation board provided and then covered with non-

combustible slate (A). The thickness of the riser (B)
is 4” (102mm). The thickness of the slate (A) is 2”
(52mm). A+B=C which is 6” (152mm). In summary,
the fireplace must be raised by the same thickness
of any material added in front of the fireplace.
If the raised hearth is deeper or wider than the
Insulation Board provided with the unit, additional
non-combustible materials such as Backer Board
(cement board) can be used to build up to the same
thickness as the Insulation Board.
All header, ceiling or shelf dimensions are measured
from the floor that the fireplace sits on. Failure to
maintain minimum installation dimensions can lead
to elevated temperatures, fire or personal injury.
For optional Reduced Ceiling Height installations,
