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 Specifi cation 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 fl ue liner but not past the inner surface.
Firmly grout or cement the clay liner in place to the chimney fl ue 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
fl ush with the inside of the masonry chimney fl ue, 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 fi berglass 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 fi t 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 fl ue 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
fl ue liner.
