Leveling Leg

• 

The firebrick (refractory), glass doors, screen rails, screen 

mesh and log grates can be removed from a factory-built 
firebox in order to gain minimum insert opening require-
ments.

•  Any smoke shelves, shields and baffles may be removed 

from a factory-built firebox if attached with mechanical fas-
teners.

• 

The metal floor of the factory-built firebox 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 floor of outer wrap.

Figure 11.1. Measure and mark the metal 
floor for cutting.  With a drill, make a starter 
hole in each corner.

Figure 11.2.  Using a saws-all, cut out the 
floor.

Figure 11.3.   If the floor 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 11.4.  Place the insert into the fac-
tory-built firebox.  Ensure that the power 
cord can not be damaged by the sharp metal 
edge.  You may need to cut out a notch to 
accomodate the cord.

Figure 11.5.  Ensure that the leveling leg is 
positioned over the 2 x 4 before leveling the 
insert.

The following is only one example as there are many differ-
ent models of factory-built fireplaces.
