3.6 Clearances to Combustibles
Refer to Figure 3-7, Figure 3-6, Table 3-2 and Table 3-3 for clearances to combustibles of the FLAIR insert.
Table 3-2: Clearances to Combustibles
Note that the non-combustible hearth must
extend a minimum of 16
” for USA (406 mm) and
18
’’ (457 mm) for Canada from the front of the
door
and 8” (203mm) on each side of the
masonry fireplace opening.
WARNING: Keep a
minimum distance of 5’ (152 cm) from the
unit to any combustible material (such as
firewood, furniture, and drapes) as a fire
hazard precaution.
The depth of the mantle is measured from the
face of the fireplace door. When the non-
combustible wall is recessed, the depth of the
mantle can be increased by the amount of the
recess.
Note that a mantel cannot be installed
below the minimum clearance of 13
” from the
bottom of the mantel to the top edge of the
door.
