Aspen Woodburning Stove

U.S. Requirements:

The National Fire Protection Association (NFPA) has established guidelines for use in the United States for passing chimney connectors through combustible walls. Many building code inspectors follow these guidelines.

Figure 9 shows one NFPA-approved method. All com- bustible material in the wall is cut away to provide 12” (305 mm) clearance to the connector. Brick and mortar are used to enclose the clearance area.

Alternate methods approved by the NFPA:

•Using a section of double-wall chimney with a 9” (229 mm) clearance to combustibles. (Fig. 10)

•Placing a chimney connector pipe inside a steel double-wall ventilated thimble, which is then sepa- rated from combustibles by 6” (152 mm) of fiberglass insulating material. (Fig. 11)

•Placing a chimney connector pipe inside a section of 9” (229 mm) diameter, solid-insulated, factory-built chimney, with two inches of air space between the chimney section and combustibles. (Fig. 12)

Canadian Requirements:

In Canada, the Canadian Standards Association has established specific guidelines regarding wall pass- though design. Figure 13 shows one approved method in which all combustible material in the wall is cut away to provide the required 18” (457 mm) clearance around the connector. The resulting space must remain empty. A flush-mounted sheet metal cover may be used on one side only. If covers must be used on both sides, each cover must be mounted on noncombustible spacers at least 1” (25 mm) clear of the wall. Your local dealer or your local building inspector can provide details of other approved methods of passing a chimney connector through a combustible wall.

In Canada, this type of installation must conform to CAN/CSA-B365, Installation Code for Solid Fuel Burn- ing Appliances and Equipment.
