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 exceptions:
•
When unit is recessed, the side walls surrounding the unit must not extend beyond unit front edge (Figure 6).
•
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 6).
Table 8: Minimum Clearances *
clearance immediately in front of viewing area(s)
* 3" (76 mm) above any horizontal/inclined vent component.
** See Page 20 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 fireplace. 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
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.
