Standard Specification for Clay Flue Liners and Chimney Pots

ABSTRACT
This specification establishes the criteria for acceptance, prior to installation, of clay flue liners and chimney pots used for conveying hot gases in masonry chimneys. The liners and pots shall be manufactured from fire clay, shale, surface clay, or a combination of these materials that when formed and fired to suitable temperatures, shall yield a product that is strong, durable, serviceable, and conforms to this specification. The liners and pots shall be subjected to absorption, acid resistance, and freeze-thaw cycle tests.
SCOPE
1.1 This specification establishes the criteria for acceptance, prior to installation, of clay flue liners and chimney pots used for conveying hot gases in masonry chimneys.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 For installation of clay flue liners, see Practice C1283.
