Method A. 12” (305 mm) Clearance to Combustible Wall Member : Using a minimum thickness 3.5” (89 mm) brick and a 5/8” (16

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 mini- mum of 12” (305 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 flue liner but not past the inner surface. Firmly grout or cement the clay liner in place to the chimney flue liner.

Method B. 9” (229 mm) Clearance to Combustible Wall Member:

Using a 6” (153 mm) inside diameter, listed, factory-built Solid-Pak chimney section with insulation of 1” (26 mm) or more, build a wall pass-through with a minimum 9” (229 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” (229 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 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” (153 mm) Clearance to Combustible Wall Member : Starting with a minimum 24 gage (.024” [.61 mm]) 6” (153

mm)metal chimney connector, and a minimum 24 gage ventilated wall thimble which has two air channels of 1” (26 mm) each, con- struct a wall pass-through. There shall be a minimum 6” (153 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” (153 mm) space. There should also be a support sized to fit and hold the metal chimney connec- tor. See that the supports are fastened securely to wall surfaces on all sides. Make sure fasteners used to secure the metal chim- ney connector do not penetrate chimney flue liner.

Min. Chimney Clearance from Masonry to Sheet Steel Supports & Combustibles – 2 in. (51mm)

Method D. 2” (51 mm) Clearance to Combustible Wall Mem- ber: Start with a solid-pak listed factory built chimney section at least 12” (304 mm) long, with insulation of 1” (26 mm) or more,

and an inside diameter of 8” (2 inches [51 mm] larger than the 6” [153 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” (26 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 sup- ports. See that the supports are fastened securely to wall surfaces on all sides. Make sure fasteners used to secure chimney section do not penetrate chimney flue liner.

1.Connectors to a masonry chimney, excepting method B, shall extend in one continuous section through the wall pass-through system and the chimney wall, to but not past the inner flue liner face.

2.A chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a floor, or ceiling.

3.Where passage through a wall, or partition of combustible construction is desired, the installation shall conform to CAN/CSA-B365.
