MINIMUM CLEARANCES TO COMBUSTIBLES
Hearth Extension A hearth extension is not required with this appliance. If a hearth extension is
used, do not block the lower control compartment door. Any hearth extension used is for appear-
ance only and does not have to conform to standard hearth extension installation requirements.
See Figure 7.
Wall Finishes / Surrounds / Mantels
Note: Combustible wall finish materials and/or surround materials must not be allowed to encroach
the area defined by the appliance front face (black sheet metal). Never allow combustible materials
to be positioned in front of or overlapping the appliance front face. See Figure 58 on Page 31.
Non-combustible materials, such as surrounds and other appliance trim, may be installed on the
appliance front face with these exceptions: they must not cover any portion of the removable glass
panel or louvers.
Vertical installation clearances to combustible mantels vary according to the depth of the mantel.
See Figure 7. Mantels constructed of non-combustible materials may be installed at any height
above the appliance opening; however, do not allow anything to hang below the hood.
NOTE: We recommend the use of high temperature paint (rated 175° F or higher) on the underside
of the mantel.
