1、Designation: C1283 11Standard Practice forInstalling Clay Flue Lining1This standard is issued under the fixed designation C1283; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses ind
2、icates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the minimum requirements forinstalling clay flue lining for residential concrete or masonrychimneys.1.2 The values stated in inch-pound uni
3、ts are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsib

T
22、he flueliner shall contact the chimney wall only as necessary forsupport and alignment in order to permit the flue liner toexpand and contract freely. The separation of the flue linerfrom the surrounding concrete or masonry shall not exceed thewall thickness of the flue liner. Where seismic reinforc
