FIREPLACE FRAMING
FIREBOX FRAMING FOR CDVT33/36
Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following Figure 3 and
the chart below for your specific installation requirements. See Figure 4 on Page 10 for firebox dimensions. The framing
headers may rest on the top of the firebox standoffs. Do not bring headers below top of standoffs.
The firebox may be installed directly on a combustible floor or raised on a platform of an appropriate height. When the
firebox is installed directly on carpeting, tile, or other combustible material, other than wood flooring, the firebox shall be
installed on a metal or wood panel extending the full width and depth of the enclosure.
