Chimney Requirements
NOTICE:
A maximum of two pairs of offsets and returns
may be used.
WARNING! Risk of Fire!
You must maintain 2 in. (51 mm)
air space clearance to insulation and other combustible
materials around the chimney system. Failure to do so
may cause overheating and fire.
NOTICE:
You must provide support for the pipe during
construction and check to be sure inadvertent loading has
not dislodged the chimney section from the fireplace or at
any chimney joint.
