22、d by Technical Committee CEN/TC 295 “Residential solid fuel burning appliances”, 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 March 2011, and conflictin
23、g national standards shall be withdrawn at the latest by June 2012. 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 has
24、been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CEN
25、ELEC 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, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuan

DIN EN 15821:2011-01 EN 15821:2010 (E) 5 1 Scope This European Standard covers multi-firing sauna stoves in which the heating stones are separated from and in
27、directly heated by the fire and the flue gases and which may be re-fuelled with several fuel loads. This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) of multi-firing sauna stoves fired by wood logs and pr
28、ovides instructions for them. Furthermore, it also gives provisions for evaluation of conformity (i.e. initial type testing (ITT) and factory production control (FPC) and marking of these products. This standard is applicable to hand-fuelled intermittent burning multi-firing sauna stoves, which prov
29、ide heat into the space where they are installed. These multi-firing sauna stoves may be supplied either as an assembled appliance or as a manufacturers pre-designed unit consisting of pre-fabricated components designed to be built on site in accordance with the manufacturers specified assembly inst
30、ructions. One-off installations are not included. These multi-firing sauna stoves may burn only natural wood logs in accordance with the appliance operating instructions. Single-firing heat storage sauna stoves, in which the stones are directly heated by the fire and the flue gases, which pass throu
31、gh them, are not covered by this European Standard. This standard is also not applicable to mechanically fed sauna stoves, sauna stoves having fan assisted combustion air, sauna stoves fitted with a boiler, sauna stoves with incorporated flue or sauna stoves having any electrical connection. 2 Norma
