FIREBOX FRAMING

Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following Figures 9 through 12 and the chart below for your specific installation requirements. See Figure 1 on Page 6 for firebox dimensions. The framing headers may rest on the top of the firebox 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.

The classification "noncombustible material" includes, but is not limited to: stone, brick, and mortar. Noncombustibles are safe to overlay the black-painted metal face, including radiant plates, and do not pose a fire hazard. Any noncombustible finish material must not extend past or interfere with the fireplace opening.

The classification "combustible material" incudes, but is not limited to: plywood, drywall, and particle board. Combustible materials may contact the sides, bottom, or back of the firebox. Do not overlay the black painted face with combustible matierals.

WARNING

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