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 wall thimble, and cover
its opening with a 24-gage minimum sheet metal support. Maintain the
6" (152.4 mm) space. There should also be a support sized to fit and
hold the metal chimney connector. See that the supports are fastened
securely to wall surfaces on all sides. Make sure fasteners used
to secure the metal chimney connector do not penetrate chimney flue
liner.
Method D: 2" (50.8 mm) Clearance to Combustible Wall Member:
Start with a solid-pak listed factory built chimney section at least 12"
(304 mm) long, with insulation of 1" (25.4 mm) or more, and an inside
diameter of 8" (2 inches [51 mm] larger than the 6" [152.4 mm]
chimney connector). Use this as a pass-through for a minimum 24-
gage single wall steel chimney connector. Keep solid-pak section
concentric with and spaced 1" (25.4 mm) off the chimney connector
by way of sheet metal support plates at both ends of chimney
section. Cover opening with and support chimney section on both
sides with 24 gage minimum sheet metal supports. See that the
supports are fastened securely to wall surfaces on all sides. Make
sure fasteners used to secure chimney flue liner.
