• Facing and/or finishing materials must never overhang
into the firebox opening.
• See Figures 7.1 and 7.2 for combustible and non-
combustible mantle and mantle leg clearance
requirements.
• Maintain all listed clearances when applying combustible
materials.
• Seal joints between the finished wall and firebox top and
