COMBUSTIBLE WALL FLUE

CONNECTOR PASS-THROUGHS

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
Specification 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 flue liner but not past the inner
surface. Firmly grout or cement the clay liner in place to the flue 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
flue 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 flue 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 flue length,
do not penetrate the flue liner (the inside wall of the Solid-Pak flue).
The inner end of the Solid-Pak flue section shall be flush with the inside
of the masonry flue, 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
flue 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
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
flue connector. See that the supports are fastened securely to wall
surfaces on all sides. Make sure fasteners used to secure the metal
flue connector do not penetrate flue liner.
Method D: 2" (50.8 mm) Clearance to Combustible Wall Member:
Start with a solid-pak listed factory built flue 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] flue
connector). Use this as a pass-through for a minimum 24-gage single
wall steel flue connector. Keep solid-pak section concentric with and
spaced 1" (25.4 mm) off the flue connector by way of sheet metal
support plates at both ends of flue section. Cover opening with and
support flue 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 flue liner.
