COMBUSTIBLE WALL CHIMNEY
CONNECTOR PASSTHROUGHS
Method A - 12” (304.8 mm) Clearance to Combustible
Wall Member: Using a minimum thickness 3.5” (89 mm)
brick and a 5/8” (15.9 mm) minimum wall thickness clay
liner, construct a wall pass-through. The clay liner must
conform to ASTM C315 (Standard Specification for
Clay Fire Linings) or its equivalent. Keep a minimum of
12” (304.8 mm) of brick masonry between the clay liner
and wall combustibles. The clay liner shall run from the
brick masonry outer surface to the inner surface of the
chimney 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 gauge (.024”
[.61 mm]) 6” (152.4 mm) metal chimney connector, and
a minimum 24 gauge 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-gauge minimum sheet metal support. Maintain the
INSTALLATION
