BS EN 12809:2001+A1:2004 Page 4 1 Scope This European Standard specifies requirements relating to the design, manufacture, construction, performance (efficiency and emission), safety, instructions and marking together with associated test methods and test fuels for type testing
30、 residential independent boilers fired by solid fuel. This standard is applicable to hand and automatically fired appliances having nominal heat outputs up to 50 kW, the primary function of which is to provide hot water for central heating and/or domestic use, and which are designed for use only wit
31、h open vented systems at a working pressure not exceeding 2 bar. In addition to their primary function of providing hot water these appliances also provide space heating to the place of installation. These appliances may burn either solid mineral fuels, peat briquettes or natural or manufactured woo
32、d logs or be multi-fuel in accordance with the appliance manufacturers instructions. This standard is not applicable to independent boilers for hot water only production and having heat outputs of less than 5 kW. This standard is also not applicable to the design and construction of automatic stokin
