Combustible Wall Chimney Connector Pass-Throughs

NOTES:

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.

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 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" (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 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" (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

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" (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

Make sure fasteners used to secure chimney flue liner.

all sides.
