Note: Your firebox is designed to be used in 
zero clearance installations. Wall or framing 
material can be placed against any exterior 
surface on the rear, sides, top or bottom of 
your firebox, except where standoff spacers 
are integrally attached. If standoff spacers are 
attached to your firebox, these spacers can 
be placed directly against wall or framing ma-
terials. Use the dimensions shown for rough 
opening to create the easiest installation.
