Refer to Figure 22 and Table 2 for the minimum clearance to combustibles:
Note that the non-
combustible hearth must extend a minimum of 20” (508mm) from the front and 8”
(203mm) on each side of the masonry fireplace opening.
WARNING: Keep a minimum distance of
5’ (152cm) 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 36.75
” (from the
bottom of the mantel to the base of the unit).
