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). Never allow combustible materials
to 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 control compartment.
Vertical installation clearances to combustible mantels vary
according to the depth of the mantel. Mantels constructed of noncombustible 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, use finish materials rated
175 °F, or higher, on the underside of the mantel.
