extension
If the value (D) is negative or zero, additional floor protection in front of the unit is not needed
because the masonry fireplace hearth extension is long enough. If the value (D) is positive, an
additional floor protection in front of the hearth extension at least equivalent to the result (D)
must be added.
9.2.2
Installation Raised of 2" (51 mm) and Less
If non-combustible material floor protection needs to be added in front of and level with the
hearth extension of the masonry fireplace (F = 2" [51 mm) or less), an R-value equal to or greater
than 1.00 is required and should extend at least 20" (508 mm) in front of the unit (B). Refer to
«Figure 15: Additional Floor Protection - Not Raised Installation»
9.2.3
Installation Raised of More Than 2" (51 mm)
If the extension of the masonry hearth is raised at least 2" (51 mm) from the floor protection, a non-
combustible material, without an R-value, must extend at least 16" (406 mm in USA) or 18" (457 mm
in Canada) in front of the unit (B). Refer to
9.2.4
With a projection kit
It is possible to position the insert with a 2" (51mm) or 4" (102mm) projection in front of the fireplace
with the use of the projection kit option. The choice of configuration will depend on compliance
with previous installation instructions and compliance with building code requirements.
It is necessary to have a floor protection made of non-combustible materials without R factor
respecting the measures indicated in the table below. This table may be used only if the masonry
hearth is raised at least 4"(102 mm) above the combustible floor.
