FIREPLACE FRAMING 
Firebox framing can be built before or after the appliance is set in place. Construct firebox framing following 
Figures 8 through 11 and the chart below for your specific installation requirements. See Figure 1 on Page 6 for 
firebox dimensions.  The framing headers may rest on the top of the firebox standoffs.
The firebox may be installed directly on a combustible floor or raised on a platform of an appropriate height. 
When the firebox is installed directly on carpeting, tile, or other combustible material, other than wood flooring, 
the firebox shall be installed on a metal or wood panel extending the full width and depth of the enclosure.
Figure 8 - Corner Installation 
Figure 10 - Stud Location 
Figure 9 - Inside Chase Installation 
Figure 11 - Recessed Installation 
Do not fill spaces around firebox with insulation or other materials. This could cause 
a fire.
