insulation of 1" (25.4 mm) or more, build a wall
pass-through with a minimum 9” (22.86 cm) 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" (22.86 cm) 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" (15 cm) Clearance to Combustible Wall
Member: Starting with a minimum 24 gage (.024"
[.61 mm]) 6" (15 cm) 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" (15
cm) 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" (5 cm) Clearance to Combustible Wall
Member: Start with a Solid-Pak listed factory built
chimney section at least 12" (30 cm) long, with
insulation of 1" (25.4 mm) or more, and an inside
diameter of 8" (2 inches [5 cm] larger than the 6" [15
cm] 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.
