This European
33、 Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2008, and conflicting national standards shall be withdrawn at the latest by February 2008. This document has been prepared under a mandate given to CEN
34、 by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national st

37、 domestic flueless space heating appliances having a nominal input not exceeding 6 kW (based on net calorific value). It covers the following Type AASfixed flueless heaters: NOTE These are type A appliances fitted with an atmosphere sensing device, with or without a fan. a) heaters with or without a
38、 catalytic converter; b) Category 1 appliances burning gases of the second family; c) Category 2 appliances burning gases of the second and third families. It does not cover i. Mobile heaters. ii. Category 1 appliances burning gases of the third family. iii. Portable flueless heaters. iv. Diffusive
39、catalytic combustion heaters. There are no specific thermal efficiency requirements appropriate to these types of appliance as: All the heat produced by the combustion process is released into the space to be heated. The requirements with regard to the combustion performance, which is a safety matte
40、r, ensure the effective burning of the fuel gas. This standard is only applicable to appliances which are to be type tested. Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary devices are not dealt with by this standard. 2 Normative r
