1 Scope
This European Standard specifies 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. It also gives information on commissioning,
cleaning and maintenance of an installed chimney.
This standard does not cover the design, installation, commissioning, cleaning and maintenance of chimneys
designated H (high positive pressure chimney) and chimneys for roomsealed appliances.
This standard also specifies limitations for supporting a chimney, and the maximum unsupported chimney height
for system chimneys and custom-built chimneys within or against a building, and for supporting by a mast or other
structures than a building.
This European Standard does not apply to structurally independent (free-standing or self-supporting) chimneys.
2 Normative references
