Wall Finishes / Surrounds / Mantels
NOTE:
Combustible wall finish materials and/or surround materials must not be allowed to encroach the area
defined by the fireplace front face (black sheet metal).
Non-combustible material up to 6 inches in depth, such as
surrounds may be positioned in front of or overlapping the fireplace face.
Non-combustible materials, such as surrounds and other fireplace trim, may be installed on the fireplace face, but they
must not cover any portion of the removable glass panel or impede the removal or installation of screen barrier assembly.
Vertical installation clearances to combustible mantels vary according to the depth of the mantel
(
Figures 5
and
5A
)
. Mantels constructed of non-combustible materials may be installed at any height above the fireplace opening.
However, do not allow anything to hang below the fireplace hood.
Minimum clearance requirements include any projections such as shelves, window sills, mantels, etc. above the
fireplace.
NOTE:
To avoid heat-related finish damage, we recommend the use of high temperature paint (rated 175° F or higher) on
the underside of the mantel.
