EN 13384-1. This European Standard does not itself provide the diagrams and/or tables for use in the design of a chimney; it provides only the method to create these diagrams and tables. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1443:2003, Chimneys — General requirements EN 13384-1:2002, Chimneys — Thermal and fluid dynamic calculation methods — Part 1: Chimneys serving one appliance EN 13384-2:2003, Chimneys — Thermal and fluid dynamic calculation methods — Part 2: Chimneys serving more than one heating appliance EN 12391-1:2003, Chimneys — Execution standard for metal chimneys — Part 1: Chimneys for non-roomsealed heating appliances 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 1443:2003,
EN 13384-1:2002, EN 13384-2:2003 and EN 12391-1:2003 apply. 4 Principle of the method The purpose of the method is to simplify the determination of the performance of chimneys using the procedures of EN 13384-1, by the production of tables or diagrams giving the result of predetermined conditions. The basis of the calculation is EN 13384-1. Normative Annex A gives a list of all the characteristics for which a value shall be given and how the values should be specified. Figure 1 is a diagrammatic representation of some of the symbols used in the calculation method. SIST EN 13384-3:2006

Figure 1 – Diagrammatic representation of some symbols The method for producing a table is to undertake the calculation for a single condition and repeat the calculation for the range of parameters. Where a diagram or table covers a range of parameters it is necessary to specify the limiting conditions e.g. for a connecting flue pipe the minimum diameter allowed and/or the maximum length, and/or number and type of bends. A typical diagram would cover the determination of the chimney diameter for a range of chimney heights or appliance outputs for a specified construction and appliance type. 5 Procedure Determine the range/scope for the diagram or table e.g. based on fuel type, appliance type and chimney construction. NOTE All diagrams/tables eventually give either a chimney size for a particular application i.e. a diameter for a chimney serving a particular appliance of x kW or which appliance can be fitted to a particular chimney configuration. Collect the data and fill in the table of the normative Annex A. For each characteristic it is necessary to specify where the value is to be identified (information source), the value or range for which the diagram or table is valid, and the values which are used for the calculation. Annex B gives an example of the data used, and the resulting diagram for determining which appliance can be used with an existing chimney. Annex C gives an example for producing diagrams for new built chimneys. Annex D gives an example for producing a table for determining the maximum heat output of an appliance possible for a particular existing chimney construction, or for a new chimney the size needed for a particular appliance type and heat output.
