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 appearance only and does not have to conform to standard hearth extension installation requirements.
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 Figures 55 and 56 on page 23.
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 glass or louvers; they may cover any portion of the top radiant panel or the air gaps surrounding the top radiant
panel up to the installed hood.
Vertical installation clearances to combustible mantels vary according to the depth of the mantel. (See Figure 58 ). 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.
Combustible materials may project beyond the
sides of the fireplace opening as long as they
are kept within the shaded areas illustrated in
Figure 57 .

COLD CLIMATE INSULATION

If you live in a cold climate, seal all cracks around your appliance with noncombustible material and wherever cold air could enter the room. It is especially
important to insulate outside chase cavity between studs and under floor on which appliance rests, if floor is above ground level.
