PRE-INSTALLATION INFORMATION

FIREPLACE FRAMING

Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following Figure 2 and the chart below for your specific installation requirements. See Figure 3 on Page 8 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.

WARNING

Do not fill spaces around firebox with insulation or other materials. This could cause a fire.
