FIREPLACE FRAMING
Firebox framing can be built before or after the appliance is set in place. Construct fi rebox framing following
Figures 8
through 11
and the chart below for your specifi c installation requirements.
See Figure 1 on Page 6
for fi rebox dimensions.
The framing headers may rest on the top of the fi rebox standoffs.
The fi rebox may be installed directly on a combustible fl oor or raised on a platform of an appropriate height. When the
fi rebox is installed directly on carpeting, tile, or other combustible material, other than wood fl ooring, the fi rebox shall be
installed on a metal or wood panel extending the full width and depth of the enclosure.
