MASONRY CHIMNEY (cont’d)
System 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 combustibles.
Use sheet metal supports fastened securely to wall sur-
faces 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 ma-
sonry chimney flue, and sealed with a non-water soluble
refractory cement. Use this cement to also seal to the
brick masonry penetration.
System 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 connec-
tor, and a minimum 24 gage ventilated wall thimble
which has two air channels of 1" (25.4 mm) each, con-
struct a wall pass-through. There shall be a minimum
6" (152.4) mm separation area containing fiberglass in-
sulation, 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 con-
nector. 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.
System D: 2" (50.8 mm) Clearance to Combustible Wall
Member: Start with a solid-pak listed factory built chim-
ney 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 sup-
ports are fastened securely to wall surfaces on all sides.
Make sure fasteners used to secure chimney flue liner.
