CHimneY instAllAtion tHrougH wAll:
Here are four (4) methods of combustible wall chimney connector pass-throughs. Information was provided from NFPA 211.
Method A. 12” (304.8 mm) Clearance to Combustible Wall Member:
Using a minimum thickness 3.5” (89 mm) brick and a ⅝” (15.9 mm)
minimum wall thickness clay liner, construct a wall pass-through. The
clay liner must conform to ASTM C315 (Standard Specication for Clay
Fire Linings) or its equivalent. Keep a minimum of 12” (305 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 ue liner but not past the inner surface. Firmly grout or
cement the clay liner in place to the chimney ue liner.
Method B. 9” (229 mm) Clearance to Combustible Wall Member: Using
a 6” (152 mm) inside diameter, factory-built Solid-Pak chimney section
with insulation of 1” (25.4 mm) or more, build a wall pass-through
with a minimum 9” (229 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” (229
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 ush with the
inside of the masonry chimney 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 gauge (.024” [0.6 mm]) 6” (152.4 mm)
metal chimney connector and a minimum 24 gauge 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 berglass insulation, from the outer surface of the wall
thimble to wall combustibles. Support the wall thimble and cover its
opening with a 24 gauge minimum sheet metal support. Maintain the
6” (152.4 mm) space. There should also be a support sized to 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 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” [51 mm] larger than the 6” [152.4 mm] chimney
connector). Use this as a pass-through for a minimum 24 gauge 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,
and support chimney section on both sides, with 24 gauge minimum
sheet metal supports. See that the supports are fastened securely to
wall surfaces on all sides.
Make sure fasteners are used to secure
chimney ue liner.

NOTES:
1. Connectors to a masonry chimney, excepting method B, shall extend in one continuous section through the wall pass-through
system and the chimney wall, to but not past the inner ue liner face.
2. A chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a oor, or ceiling.
