MINIMUM CLEARANCES TO COMBUSTIBLES
Appliance And Vent Clearances
Maintain clearances from appliance to combustible materials as detailed in
Table 6 with the following exception: When the unit is installed with one
side flush with a wall, the wall on the other side of the unit must not
extend beyond the front edge of the unit. In addition, when the unit is
installed in the middle of a room, the side walls surrounding the unit must
not extend beyond the front or rear edge of the unit. See Figure 3.
Hearth Extension - A hearth extension is not required with this appliance.
If a hearth extension is used, do not block the control compartment access
panel. Any hearth extension used is for appearance only and does not have
to conform to standard hearth extension installation requirements.
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 37.
Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance front and back faces with the following
exception: The material must NOT cover any portion of the glass, louvers
or top radiant panel (optional kit).
Vertical installation clearances to combustible mantels vary according
to the depth of the mantel. (See Figure 5). 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.
These instructions should be used as a guideline and do not supersede
local codes in any way.
