EN 14543:2017 (E) 5 European foreword This document (EN 14543:2017) has been prepared by Technical Committee CEN/TC 181 “Dedicated liquefied petroleum gas appliances”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2018, and conflicting national standards shall be withdrawn at the latest by January 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14543:2005+A1:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 2009/142/EC of the European Parliament and of the Council of 30 November 2009 relating to appliances burning gaseous fuels. For relationship with EU Directive 2009/142/EC, see informative Annex ZA, which is an integral part of this document. The following changes were implemented with regard to the previous edition:
addition of max pressure in the scope;
access to the cylinder valve (only one hand movement without the use of any key or tool);
limitation of the ignition output to 5 kW;
requirement for internal flexibles;
distinction between wall mounted, suspended and grounded appliances;
requirement for water protection of electrical equipment;
removal of any reference to EN 449 compliant appliances;
addition of warning of the changing of tubing or flexible. Annexes A, B and ZA are informative. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 14543:2017 (E) 6 1 Scope This European standard specifies the design, safety and marking requirements and test methods for flueless patio heaters for outdoor or amply ventilated area use only. These appliances are for use exclusively with gases of the third family as defined in Clause 4. This European standard applies to appliances that have a nominal heat input not exceeding 17 kW (based on the gross calorific value), supplied with a maximum inlet pressure of 50 mbar: — fixed or, — movable, including those which comprise a housing for a transportable and rechargeable liquefied petroleum gas cylinder. This European standard does not apply to appliances equipped with a fan for either combustion or circulation of the convection air. This European standard does not cover LPG containers for liquefied petroleum gas, their associated regulator, tubing and flexible hoses used for gas supply of appliances covered by this European standard. Regulator, tubing and flexible hoses are covered by others standards (EN 16129, EN 16436-1 and prEN 16436-2, etc.) and national regulations. This European standard does not lay down any specific requirements for the thermal efficiency of this type of appliances, but the requirements relating to combustion, which is a safety matter, ensure that the gas fuel will burn efficiently. However a method to measure the performance is described in informative Annex B. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
