Through Wall Installations
System A. Minimum 3.5 in. (90 mm) thick brick masonry
wall framed into combustible wall with a minimum of 12 in.
(305 mm) brick separation from clay liner to combustibles.
Fireclay liner (ASTM C 315, Standard Specifi cations for
Clay Fire Linings, or equivalent), minimum 5/8 in. (16 mm)
wall thickness, shall run from outer surface of brick wall to,
but not beyond, the inner surface of chimney fl ue liner and
shall be fi rmly cemented in place.
Clearance: 12 in. (305 mm)
System B. Solid-Insulated, listed factory-built chimney length
of the same inside diameter as the chimney connector
and having 1 in. (25.4 mm) or more of insulation with a
minimum 9 in. (229 mm) air space between the outer wall
of the chimney length and combustibles.
The inner end of the chimney length shall be fl ush with the
inside of the masonry chimney fl ue and shall be sealed
to the fl ue and to the brick masonry penetration with
non-water-soluble refractory cement. Supports shall be
securely fastened to wall surfaces on all sides.
Fasteners between supports and the chimney length shall
not penetrate the chimney liner.
Clearance: 9 in. (229 mm)
System C. Sheet steel chimney connector, minimum 24 gauge
[0.024 in. (0.61 mm)] in thickness, with a ventilated thimble,
minimum 24 gauge [0.024 in. (0.61 mm)] in thickness,
having two 1 in. (25.4 mm) air channels, separated from
combustibles by a minimum of 6 in. (152 mm) of glass
fi ber insulation. Opening shall be covered, and thimble
supported with a sheet steel support, minimum 24 gauge
[0.024 in. (0.61 mm))] in thickness.
Supports shall be securely fastened to wall surfaces on all
sides and shall be sized to fi t and hold chimney section.
Fasteners used to secure chimney section shall not
penetrate chimney fl ue liner.
Clearance: 6 in. (152 mm)
System D. Solid-Insulated, listed factory-built chimney length
with an inside diameter 2 in. (51 mm) larger than the
chimney connector and having 1 in. (25.4mm) or more
of insulation, serving as a pass-through for a single-wall
sheet steel chimney connector of minimum 24 gauge
[0.024 in. (0.61 mm)] thickness, with a minimum 2 in. (51
mm) air space between the outer wall of chimney section
and combustibles.
Minimum length of chimney section shall be 12 in. (305
mm). Chimney section concentric with and spaced 1 in.
(25.4 mm) away from connector by means of sheet steel
support plates on both ends of chimney section. Opening
shall be covered, and chimney section supported on both
sides with sheet steel supports of minimum 24 gauge
[0.024 in. (0.61 mm)] thickness.
Supports shall be securely fastened to wall surfaces on all
sides and shall be sized to fi t and hold chimney section.
Fasteners used to secure chimney section shall not
penetrate chimney fl ue liner.
Clearance: 2 in. (51 mm)
