24、irements cover factory-built chimneys intended for venting gas, liquid, and solid-fuel red residential-type appliances and building heating appliances in which the maximum continuous ue-gas outlet temperatures do not exceed 1000F (538C). Factory-built chimneys are intended for installation in accord
25、ance 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. They are intended for installation inside or outside of bu
26、ildings or both, in a manner that provides a vertical (30 degree maximum offset) conduit or passageway to transport ue gases to the outside. 1.2 The chimneys covered by these requirements comply with either a limited duration 1700F (927C) ue-gas temperature test or a limited duration 2100F (1149C) u
27、e-gas temperature test, at the manufacturers option. 1.3 These requirements cover dual purpose residential type and building heating appliance type chimneys, and single purpose building heating appliance type chimneys. Dual purpose residential type and building heating appliance type chimneys are te
28、sted enclosed and intended to be installed unenclosed or enclosed with combustible construction. Single purpose building heating appliance type chimneys are tested unenclosed and intended to be installed unenclosed or enclosed in a noncombustible chase. 2 Components 2.1 Except as indicated in 2.2, a
29、 component of a product covered by this standard shall comply with the requirements for that component. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this st
30、andard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are inte
31、nded for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.
