This standard does not cover:  chimneys designated H (high positive pressure chimneys), and chimneys designated P (normal positive pressure chimneys) serving more than one appliance,  chimneys which serve a mixture of fan assisted or forced draught burners or natural draught appliances,  installations having a configuration of the type C2. This European Standard does not apply to freestanding chimneys covered by EN 13084-1. This standard also specifies limitations for supporting a chimney, and the maximum unsupported chimney height for system chimneys and custom built chimneys. NOTE Roomsealed gas appliances are classified as type C according to CEN/TR 1749. 2 Normative references The following referenced documents are indispensable for the application of this document.

3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 1443:2003, EN 15287-1:2007 and the following apply. NOTE 1 Examples of balanced air/flue configurations for roomsealed applications are given in Figures 1 and 2. The configurations of Figure 1 and Figure 2 may be created from converting or relining an existing chimney. NOTE 2 The European scheme for the classification of gas appliances is given in CEN/TR 1749.
3.1 air supply duct duct in a chimney system only for conveying combustion air to a room-sealed appliance 3.2 balanced flue chimney configuration configuration where the air entry to the combustion air supply duct is adjacent to the discharge of combustion products from the flue, the inlet and outlet being so positioned that wind effects are substantially balanced 3.3 concentric chimney configuration configuration in which the chimney flue is fully surrounded by the air supply duct NOTE This includes chimney configurations where the flue duct and air supply duct do not share a common axis. 3.4 connecting air supply pipe component or components connecting the heating appliance air supply to the chimney system air supply duct

3.7 custom-built chimney for roomsealed heating applications chimney configuration that is installed or built on-site using a combination of compatible components that may be from one or different sources 3.8 flue duct the duct containing the flue of the chimney system 3.9 relined chimney existing chimney where a liner is restored or replaced NOTE The process of inserting a new liner into an existing chimney without a change of the air/flue configuration is also regarded as relining the chimney 3.10 roomsealed appliance appliance in which the combustion circuit (air supply, combustion chamber, heat exchanger and evacuation of the products of combustion) is sealed with respect to the room in which the appliance is installed 3.11 roomsealed chimney configuration
combination of both a flue duct and an air supply duct for roomsealed applications 3.12 separate chimney configuration configuration in which the air supply duct and the chimney flue are separate
3.13 system chimney for roomsealed heating applications chimney configuration that is installed using a combination of compatible components, obtained or specified from one manufacturing source with product responsibility for the whole roomsealed chimney configuration NOTE This product is understood to constitute a kit under the Mandate M 105.
Key 1 flue gas 2 combustion air Figure 1 — Concentric configurations

Key 1 flue gas 2 combustion air Figure 2 — Separate configurations 4 Design 4.1 General In order to design a chimney system installation, the following steps should be followed to achieve a safe chimney installation. Specify whether the chimney system design is for a single appliance or multiple appliance application. Specify the type of multiple appliance configuration, i.e. whether cascade or multiple inlet. The design shall specify whether the chimney configuration to be installed shall comprise two concentric or separate ducts. Chimney system shall comply with national regulations and nationally accepted rules. NOTE Where a chimney is approved together with the heating appliance, the information for flue sizing or the designation parameters not associated with the installation aspects are not necessary as the combination of appliance and chimney has been certificated together. 4.2 Data requirements 4.2.1 Sources of data and information The data and information specified in 4.2.2 to 4.2.5 shall be obtained and documented as appropriate. NOTE The sources may be:
-heating appliance manufacturer‘s literature,
-chimney manufacturer‘s literature including installation instructions,
-architects drawings or plans and/or site surveys,
-Annexes of this document (e.g. material characteristics),
-local building rules. A possible source of typical or average data is EN 13384-1, and Annex A of this document. 4.2.2 Heating appliance information The information for the heating appliance(s) in Annex B shall be obtained from the documentation of the heating appliance manufacturer or if not available, default values may be used (see Annex B of EN 13384-1:2002), but the source of the data shall be documented in the design (see 4.2.1).
