APPLIANCE AND VENT CLEARANCES
The appliance is approved with zero clearance to
combustible materials on all sides (as detailed in
Table 2)
, 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 2
.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materi-
als. However, if installed on combustible mate-
rials, such as carpeting, vinyl tile, etc., a metal
or wood barrier covering the entire bottom
surface must be used.

Note:
3 in. (75 mm) above any horizontal/inclined
vent component.
