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.
