Finishing
Finish the walls with the material of your choice. Figure 4 on page 8
shows the minimum vertical and corresponding maximum horizontal
dimensions of mantels or other combustible projections above the
top front edge of the fireplace.
Only non-combustible materials may be used to cover the metal
fireplace face. See Figure 3, Page 8.
If the joints between the finished wall and the fireplace surround
(top and sides) are sealed, a 300°F minimum sealant material
must be used. These joints are not required to be sealed. Only
non-combustible material (using 300°F minimum adhesive if
needed), can be applied as facing to the fireplace surround.
Vent Runs
In planning the installation for the fireplace, it is necessary to install
certain components before the appliance is completely positioned
and installed. These include the direct vent system, gas piping for
the appliance and the electrical wiring.
The appliance can be mounted on any of the following surfaces:
1. A flat, hard combustible surface.
2. A raised wooden platform.
3. Six supports. (Example: Six concrete masonry blocks.) These
supports must be positioned so they contact all four perimeter
edges on the bottom of the unit and under the center leg supports,
if allowed by code.
