EN 15287-2 : Chimneys - Design, installation and commissioning - Part 2: Chimneys and connecting flue pipes for room sealed combustion appliances.

This standard describes the methods for specifying the design, installation and labelling criteria for chimney systems, site-built chimneys, the relining or conversion of existing chimneys, connecting flue pipes and air-supply ducts for room-sealed combustion appliances, as well as the use of components and the commissioning of a newly installed chimney. It applies where the spacing between supports does not exceed 4 m, the projection above the last fixing does not exceed 3 m, and, for a rectangular section, the free height above the highest fixing does not exceed five times the smallest external dimension. It excludes chimneys serving a combination of fan-assisted burners, forced-draught burners or natural-draught appliances, as well as C2 configurations. Room-sealed gas appliances are classified as type C in accordance with EN 1749. Part 1 deals with appliances that draw combustion air from the room.
