scope:

This document specifies requirements and the basic performance criteria for chimneys, flue liners, connecting flue pipes, components and accessories used to convey the products of combustion from combustion appliances to the outside atmosphere. This document is to be used as a reference for all product standards of CEN/TC 166.

This document specifies sootfire resistant chimneys, flue liners, connecting flue pipes, fittings and accessories for combustion appliances burning solid, liquid and gaseous fuels and non-sootfire resistant chimneys, flue liners, connecting flue pipes, components and accessories for combustion appliances burning liquid and gaseous fuels only. It also specifies sootfire safe accessories for combustion appliances burning solid, liquid and gaseous fuels.

NOTE 1 This means that chimneys, flue liners, connecting flue pipes and components which are non-sootfire resistant and accessories which are non-sootfire resistant or non-sootfire safe are not suitable for combustion appliances burning solid fuel.

This document also identifies minimum requirements for marking, instructions, product information and provides guidance for the assessment and verification of constancy of performance (AVCP).

This document does not apply to structurally independent chimneys and custom-built chimneys consisting of non-CE-marked components.

NOTE 2 This document can be used as a basis for the specifications of products covered by a European Technical Assessment.

NOTE 3 All product standards drafted by Technical Committee CEN/TC 166 are based on the Mandate M/105.
