G. Removing Metal Floor of Factory-Built
Firebox
• The fi rebrick (refractory), glass doors, screen rails,
screen mesh and log grates can be removed from a fac-
tory-built fi rebox in order to gain minimum insert open-
ing requirements.
• Any smoke shelves, shields and baffl es may be removed
from a factory-built fi rebox if attached with mechanical
fasteners.
• The metal fl oor of the factory-built fi rebox may be
removed to facilitate the installation of the insert only
when a 1/4 inch (6mm) airspace is provided between
the insert and the fl oor of outer wrap.
The following is only one example as there are many differ-
ent models of factory-built fi replaces.
Figure 10.1. Measure and mark the metal
fl oor for cutting. With a drill, make a starter
hole in each corner.
Figure 10.2. Using a saws-all, cut out the
fl oor.
Figure 10.3. If the fl oor is made of thin metal,
we recommend using the 2 x 4 from the insert
packaging to support the insert. The 2 x 4
may need to be cut to the appropriate size.
Figure 10.4. Place the insert into the facto-
ry-built fi rebox. Ensure that the power cord
can not be damaged by the sharp metal
edge. You may need to cut out a notch to
accommodate the cord.
Figure 10.5. Ensure that the leveling leg is
positioned over the 2 x 4 before leveling the
insert.
