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 Specifica-
tion 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” (228.6mm) 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 penetra-
tion.
