The fireplace is approved with zero clearance to combustible materials on all sides
(

with the following
exceptions:
• When unit is recessed, the side walls surrounding the unit must not extend beyond unit front edge
(

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
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
.
NOTE:
This is a heat-producing appliance. Objects placed above the unit are exposed to elevated temperatures.
