Scope:

These requirements apply to single walled and double walled factory-built chimney connectors. These assemblies do not require field fabrication. They are for use with solid-fuel-fired residential appliances where the flue-gas temperatures do not normally exceed 1000°F. Factory-built chimney connectors are intended for use inside buildings to form a connection from an appliance to a factory-built chimney suitable for use with solid fuel. These Factory-built chimney connectors are intended for installation in accordance with the Standard for Chimneys, Fireplaces, Vents, and Solid-Fuel Burning Appliances, NFPA 211, and in accordance with codes such as the International Mechanical Code, the International Residential Code, and the Uniform Mechanical Code.

Factory-built chimney connectors are intended to be installed at the manufacturer's recommended clearance to combustible construction or a minimum clearance of 18 in. (46 cm) to combustible construction and fabricated at the minimum material thickness for steel as required by the Standard for Chimneys, Fireplaces, Vents, and Solid-Fuel Burning Appliances, NFPA 211 and as described herein.

These requirements supplement those specified in the Standard for Factory-Built Chimneys for Residential Type and Building Heating Appliances, UL 103, and are not to supersede the requirements of UL 103. (i.e. UL 103 takes precedence over this Supplement) with the following exceptions:

a) The table shown in SA3.1.2 applies to chimney connectors, in lieu of the requirements in Table 6.1 "Minimum thickness of chimney material" of UL 103.

b) The Markings and Instructions requirements shown in SA5 and SA6, respectively, apply to chimney connectors in lieu of the Markings and Instructions requirements of UL 103.
