21、ppliances”, the secretariat of which is held by AFNOR. This document shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2007 and conflicting national standards shall be withdrawn at the latest by December 2007. Th
22、is document includes Amendment 1, approved by CEN on 2007-04-27. This document supersedes EN 14543:2005. The start and finish of text introduced or altered by amendment is indicated in the text by tags ! “. This document has been prepared under a mandate given to CEN by the European Commission and t
23、he European Free Trade Association, and supports essential requirements of EU Directive 90/396/EEC. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Annex A is normative. Annexes B,C and ZA are informative. According to the CEN/CENELEC Inte

26、ntilated area use only. Although they are not covered by this standard, the requirements of this standard are applicable to appliances that may be used inside habitations which, in addition, shall have a heat input not exceeding 4,2 kW and comply with EN 449. These appliances are for use exclusively
27、 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); fixed or, movable, including those which comprise a housing for a transportable and rechargeable liquefied pet
28、roleum 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, neither their associated regulator nor tubing and flexible hoses
29、which shall comply with national requirements in force. 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. How
30、ever a method to measure the performance is described in informative Annex C. This standard does not apply to appliances covered by EN 416-1, EN 419-1, EN 449, EN 461 and EN 521. This European standard only covers type testing. Items relating to quality assurance systems, production testing and part
31、icularly certificates of conformity of auxiliary equipment are not covered by this European standard. 2 Normative references The following referenced documents are indispensable for the application of this document.
