Owner's Manual

Firebox framing can be built before or after the appliance is
set in place. Construct rebox framing following Figure 4.1
for your specic installation requirements. Refer to Figure
4.1 on page 9 for rebox dimensions. The framing headers
may rest on the top of the rebox standoffs.
The rebox may be installed directly on a combustible oor
or raised on a platform of an appropriate height. When
the rebox is installed directly on carpeting, tile, or other
combustible material, other than wood ooring, the rebox
shall be installed on a metal or wood panel extending the
full width and depth of the enclosure.
WARNING!
Do not ll spaces around rebox with insulation
or other materials. This could cause a re.
WARNING!
The fireplace must be installed giving full
consideration to the clearance and height
requirements identied in this manual.
5. Mantel clearances: If a combustible mantel is installed,
it must meet the clearance requirements as shown in
Figures 6.3 & 6.4.
6. Floor clearance: This inner chamber rebox oor must
be installed at least 1" above any combustible ooring
material, such as carpeting or asphalt tile, which is
closer than 14" to the base of the rebox. See Figure 6.5.
Or
The inner chamber rebox oor may be installed nearer to
the oor if a minimum of 14" of noncombustible material
such as slate or marble is installed between the base of
the rebox and the combustible ooring. See Figure 6.6..
