24、:2010EN 15821:2010 (E) 5 1 Scope This European Standard covers multi-firing sauna stoves in which the heating stones are separated from and indirectly 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

25、the design, manufacture, construction, safety and performance (efficiency and emission) of multi-firing sauna stoves fired by wood logs and provides instructions for them. Furthermore, it also gives provisions for evaluation of conformity (i.e. initial type testing (ITT) and factory production contr

26、ol (FPC) and marking of these products. This standard is applicable to hand-fuelled intermittent burning multi-firing sauna stoves, which provide 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-d

27、esigned unit consisting of pre-fabricated components designed to be built on site in accordance with the manufacturers specified assembly instructions. One-off installations are not included. These multi-firing sauna stoves may burn only natural wood logs in accordance with the appliance operating i

28、nstructions. Single-firing heat storage sauna stoves, in which the stones are directly heated by the fire and the flue gases, which pass through them, are not covered by this European Standard. This standard is also not applicable to mechanically fed sauna stoves, sauna stoves having fan assisted co

29、mbustion air, sauna stoves fitted with a boiler, sauna stoves with incorporated flue or sauna stoves having any electrical connection. 2 Normative references The following referenced documents are indispensable for the application of this document.
