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 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
