Combustible wall chimney connector pass-throughs
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.
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.
