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 non-combustible caulk or trim materials to prevent cold
air leakage around the fireplace.
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 mantels and trim must be installed in
accordance with the National Fire Protection Association
- ANSI NFPA 211 Standard - Section 7-2.3.3.
