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” (304.8mm) 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 8” (203.2 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.
