METHOD B - 9" (228.6 mm) Clearance to Combustible
Wall Member: Using a 6" (152.4 mm) inside diameter,
listed, factory-built Solid-Pak chimney section with insulation
of 1" (25.4 mm) or more, build a wall pass-through with
a minimum 9" (228.6 mm) air space between the outer
wall of the chimney length and wall combustibles. Use
sheet metal supports fastened securely to wall surfaces on
all sides, to maintain the 9" (228.6 mm) air space. When
fastening supports to chimney length, do not penetrate the
chimney liner (the inside wall of the Solid-Pak chimney). The
inner end of the Solid-Pak chimney section shall be flush
with the inside of the masonry chimney flue, and sealed
with a non-water soluble refractory cement. Use this cement
to also seal to the brick masonry penetration.
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, construct 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
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.
