The noncombustible raised platform must be set
with a minimum one and one half inch (1-1/2") clearance to
the wall directly behind the Fire-Lite assembly.
Raised Platform:
Nominal four (4") metal base. (Figure 91).Set the
Fire-Lite base plate in a mortar bed on to the non-combus
-
tible raised platform.
Metal safety strip - a generic 26 ga., four inch (4”)
wide galvanized metal strip - must be inserted to approxi
-
mately two inch (2”) beneath the platform at the front of
the noncombustible raised platform. The safety strips must
extend out from the front of the raised platform at least
two inches (2”) and must extend to at least two inches (2”)
beyond the ends of the raised platform. Any overlaps in
the length of the safety strips should be a minimum of two
inches (2”) for continual coverage of the combustible floor
at the front of the fireplace (Figure 92).
The exposed combustible floor within the
perimeter formed by the noncombustible raised platform
must be completely covered with one inch thick ceramic
fiber insulation board (Figure 90). The board is dry laid to
the floor within the block perimeter.
The ceramic fiber board must have a thermal
conductivity rating equal to or greater than 0.4 Btu-in/hrsq.
ft-degree Fahrenheit. (Reference: Harbison-Walker, 600
