CHIMNEY INSTALLATION
The maximum height of chimney that can be supported by the top of the fireplace is 18 feet.
For taller
chimneys, additional supports are required. Offset or roof supports can be used.
NOTE:
The clearance between the chimney and combustible material must be at least 2".
DO NOT
fill this area
with insulation.
1. Cut and frame the required holes in the floor(s), ceiling(s) and roof where the chimney will pass through. The
rough opening in the framing is 13" square (the opening can be slightly bigger, up to 13 ½”, but NEVER
smaller).
