Chimney connector pass-throughs in combustible wall

24
Method A:
12" (304.8 mm) Clearance to Combustible
Wall Member: Using a minimum thick-
ness 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 (Stan-
dard 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 insula-
tion 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 combusti-
bles. 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 refrac-
tory cement. Use this cement to also seal
to the brick masonry penetration.
