Chimney connector pass-throughs in combustible wall
NOTES:
1. 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.
2. A chimney connector shall not pass
through an attic or roof space, closet
or similar concealed space, or a floor, or
ceiling.
Method C:
6" (152.4 mm) Clearance to Combustible
Wall Member: Starting with a minimum 24
gage (.024" [.61 mm]) 6" (152.4 mm) metal
chimney connector, and a minimum 24
gage ventilated wall thimble which has two
air channels of 1" (25.4 mm) each, con-
struct a wall pass-through. There shall be
a minimum 6" (152.4) mm separation area
containing fiberglass insulation, from the
outer surface of the wall thimble to wall
combustibles. Support the 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 pen-
etrate 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 chim-
ney section on both sides with 24 gage
minimum sheet metal supports. See that
he supports are fastened securely to wall
surfaces on all sides.
Make sure fasteners used to secure chim-
ney flue line.
