firebox framing
Firebox framing can be built before or after the appliance is set in place. Refer to Figure 2 for fireplace and framing dimensions. Construct firebox framing following Figure 2 for your specific installation requirements. 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.
