MINIMUM CLEARANCES TO COMBUSTIBLES
Fireplace And Vent Clearances
The fireplace is approved with zero clearance to combustible materials
on all sides
(
Table 8
)
, with the following exception: The unit may not
be recessed (allowance made for mantel legs / side trim in
Figure 5C,
Page 16
)
. 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
(
Figure 5C, Page 16
)
.
The fireplace must be mounted on a fully supported base extending
the full width and depth of the unit. The fireplace may be located on
or near conventional construction materials. However, if installed on
combustible materials, such as carpeting, vinyl tile or other combustible
material other than wood flooring, the appliance shall be installed on a
metal or wood panel extending the full width and depth of the appliance.

Hearth Extension
A hearth extension is not required with this fireplace. 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, the venting attached to the top vent should be routed in a way to minimize obstructions to
the space above the fireplace. Do not insulate the space between the fireplace and the area above it
(
Table 9
)
. The minimum height from
the base of the fireplace to the underside of combustible materials used to construct a utility shelf in this fashion is shown in
Table 9
.
