Appliance And Vent Clearances
The appliance is approved with zero clearance to combustible materials on
all sides (as detailed in

, 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 recessed, the side walls surrounding the unit
must not extend beyond the front edge of the unit (see
Figure 3
)
.

**NOTE: See Page 9, Step 1 for clearance requirements to the nailing
flange located at each side of the unit and any screw heads adjacent to it.
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 appearance only and does not have
to conform to standard hearth extension installation requirements.
Shelf Height -
To provide for the lowest possible shelf surface, use the
alternate rear vent outlet, the venting attached to the top vent should be
routed in a way to minimize obstructions to the space above the appliance.
Do not insulate the space between the appliance and the area above
it (see
Figure 8
).
The minimum height from the base of the appliance to
the underside of combustible materials used to construct a utility shelf in
this fashion is shown in
Figure 8
.
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 face
(see
Figures 63a and 64
on
Page 34
).
Non-combustible materials, such as surrounds and other appliance trim,
may be installed on the appliance face with these exceptions: 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. See
Figure 9
. 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 fireplace hood.
Minimum clearance requirements include any projections such as shelves,
window sills, mantels, etc. above the appliance.
NOTE:
We recommend the use of high temperature paint (rated 175° F
or higher) on the underside of the mantel.
* Includes 3” clearance to combustibles (required above vent components)
Combustible materials may project beyond one side of the fireplace
opening as long as they are kept within the shaded areas illustrated here.
