INSTALLATION
wall thimble, and cover its opening with a 24-gage
minimum sheet metal support. Maintain the 6”
(152.4 mm) space. There should also be a support
sized to fit and hold the metal chimney connector.
See that the supports are fastened securely to wall
surfaces on all sides. Make sure fasteners used
to secure the metal chimney connector do not
penetrate chimney flue liner.
METHOD D -
2” (50.8 mm) Clearance to Combustible
Wall Member: Start with a solid-pak listed factory
built chimney section at least 12” (304 mm) long,
with insulation of 1” (25.4 mm) or more, and an
inside diameter of 8” (2 inches [51 mm] larger than
the 6” [152.4 mm] chimney connector). Use this as a
pass-through for a minimum 24-gauge single wall
steel chimney connector. Keep solid-pak section
concentric with and spaced 1” (25.4 mm) off the
chimney connector by way of sheet metal support
plates at both ends of chimney section. Cover
opening with and support chimney section on both
sides with 24 gage minimum sheet metal supports.
See that the supports are fastened securely to wall
surfaces on all sides. Make sure fasteners used to
secure chimney flue line do not penetrate the inner
liner.
NOTES:
• Connectors to a masonry chimney, excepting
method B, shall extend in one continuous section
through the wall pass-through system and the
chimney wall, to but not past the inner flue liner
face.
• A chimney connector shall not pass through an
attic or roof space, closet or similar concealed
space, or a floor, or ceiling.
