Bibliography

Describes the method of specifying the design criteria and the installation method for building custom-built chimneys with rigid metal liners, for relining a chimney with rigid or flexible metal liners and for single wall system chimneys or multi-wall system chimneys with rigid metallic liners, used to convey the products of combustion from heating appliances to the outside atmosphere.
