APPLIANCE AND VENT CLEARANCES

The appliance is approved with zero clearance to
combustible materials on all sides (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 recessed, the side walls
surrounding the unit must not extend beyond
the front edge of the unit. See Figure 1.

component. See Note

**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.
***Note: To ensure proper fit of the facade
(required - sold separately). The appliance
base will need to be elevated 3/4" minimum
above the floor to allow for the proper fit of the
facade (i.e. use 3/4" board as platform).
SHELF HEIGHT
To provide for the lowest possible shelf sur-
face, the venting attached to the top vent
should be routed in a way to minimize ob-
structions to the space above the appliance.
Do not insulate the space between the appli-
ance and the area above it (see Figure 2).
The minimum height from the base of the ap-
pliance to the underside of combustible ma-
terials used to construct a utility shelf in this
fashion is shown in the table in Figure 2.
