flue liner but not past the inner surface. Firmly grout or
cement the clay liner in place to the chimney flue liner.
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-
gage 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 liner.
