APPLYING DECORATIVE TRIM TO THE FIREPLACE
Do not allow the trim materials to extend closer than 3/8 inch to the vertical edges of the firebox opening if you plan to equip the fireplace with glass doors.
The face of your fireplace may be left exposed or trimmed with any noncombustible material such as brick, stone or marble. If a trim is installed, be sure it is fastened snugly to the face of the fireplace. A crack between the material and the face of the fireplace could pose a fire hazard and impair the proper operation of the fireplace. Blocking the fireplace with framing and attaching the base to the supporting floor will further reduce the possibility of such a crack developing.
Wall ties should be fastened to the face of the fireplace with sheet metal screws and placed in the mortar joints of masonry trim.
Combustible material must not be installed below the top spacers of the fireplace or overlap the sides of the fireplace face. Seal the face of the fireplace to the surrounding wall with
The trim should not block or restrict in any way the flow of air into the side air inlets in the face of the fireplace.
Be sure to provide the required floor protection as described in a preceding section of this manual.
Combustible mantles and trim must be installed in accordance with the National Fire Protection Association - ANSI NFPA 211 Standard - Section
