22、DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements 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 1

23、000F (538C). Factory-built chimneys 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

24、Mechanical Code. They are intended for installation inside or outside of buildings 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

25、 1700F (927C) ue-gas temperature test or a limited duration 2100F (1149C) ue-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 p
