FINISHING YOUR FIREBOX 
There is a wide variety of finishing material 
available for your firebox from formal wall 
treatments with marble and mantels, to rustic 
wood paneling, stone or brick. 
IT IS IMPORTANT THAT THE BLACK FACE 
OF THE FIREBOX NOT BE COVERED WITH 
ANY TYPE OF COMBUSTIBLE MATERIAL. 
Non-combustible facing materials such as 
marble, brick, or ceramic tile may overlap the 
black face of the firebox up to the opening on 
either side of the firebox.  Seal all joints 
between the black firebox face and the wall 
covering with a heat-resistant material such as 
rock wool insulation or mortar.  Be sure to 
use high temperature adhesive or mortar when 
anchoring brick, stone, or tile to the face of 
the firebox.  Check to see whether man-made 
brick and stone are made of non-combustible 
materials before using them on the face of the 
firebox.  Some of these products contain 
combustible materials.  Combustible wall 
coverings such as paneling or wallboard may 
not  overlap the black face of the firebox.  The 
space between the wall covering and the 
firebox should be sealed with a heat resistant 
material such as rock wool insulation or 
mortar. 
NOTE:  An “L” shaped steel lintel must be 
installed across the top of the firebox 
opening where facing materials such as 
brick or stone is used on the face of the 
firebox.  It acts as a support/firestop.  It 
should be attached to the face of the firebox 
with screws and sealed to the firebox with a 
heat-resistant sealer.
