Foreword This document (EN 12662002) has been prepared by Technical Committee CENTC 62“ Independent gas-fired space heat
22、ers“, the secretariat of which is held by BSI. 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of an identical text or by endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest by April 2003. This d
23、ocument has been prepared under a mandate given to CEN by the Commission and the European Free Trade Association, and supports the essential requirements of Directive 90/396/EEC. For relationship with EU Directives, see informative annexZA, which is an integral part of thisdocument. According to the
24、 CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spa
25、in, Sweden, Switzerland and the United Kingdom. Page 4 EN 1266 : 2002 1 Scope This European Standard specifies the requirements and test methods for the construction, safety, marking and rational use of energy of independent gas-fired convection heating appliances that are fitted with fan-assisted a
26、tmospheric burners, or fully pre-mixed burners. This standard is applicable to independent convection heaters, burning gas having a fan to assist the transportation of combustion air and/or flue gases, hereafter referred to as appliances: - that are wall mounted, free-standing or built-in; - that ha
27、ve a nominal heat input not exceeding 20 kW (based on the net calorific value). In addition, this standard is applicable to live fuel effect appliances. This standard is not applicable to: a) open fronted appliances to prEN 13278:1998; b) appliances fitted with automatic forced-draught burners to EN
28、 676; c) ducted-air appliances; d) appliances installed by means of a closure plate (see 3.3.3.8). This standard is only applicable to appliances which are intended to be type tested. Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary
29、 devices are not dealt with by this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated
30、references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

Such an appliance may also contain radiant heating elements provided that it complies with all the requirements of this standard 3.1.2 forced convection heater convection appliance that incorporates a fan and thus allows an acceleration of the ci
39、rculation of the air in contact with the heating body. Such an appliance is designed to discharge air directly into the room in which the appliance is installed and not to be connected to a warm air distribution system 3.1.3 convection fan device to assist in the distribution of heated air 3.1.4 liv
