CLEARANCES and HEIGHT REQUIREMENTS

is installed, it must meet the clearance requirements
detailed in Figure 6.

" above any combustible
fl ooring material or, the fi rebox hearth
may be installed fl ush with the fl oor

slate or marble is installed between
the base of the fi rebox and the com-
bustible fl ooring.
The firebox may be
installed directly on a combustible
floor or raised on a platform of an
appropriate height. Do not place fire-
box on carpeting, vinyl, or other soft
floor coverings. It may, however, be
placed on a flat wood, plywood, par-
ticle board, or other hard surfaces. Be
sure firebox rests on a solid continuous floor or platform with
appropriate framing for support so that no cold air can enter room
from under the firebox. Refer to Figure 8.
NOTE: The combustible area above the facing must
not protrude more than 3/4" from the facing. If it does,
it is considered a mantel and must meet the mantel
requirements listed in this manual.
