This British Standard specifies requirements for the design and installation of the following types of domestic heating and cooking appliances, rated up to 50 kW, burning wood, woody biomass and solid fuels in both new and existing buildings (see Clause 6<\/b>):<\/p>\n

    \n
  1. \n

    open fires;<\/p>\n<\/li>\n

  2. \n

    room heaters;<\/p>\n<\/li>\n

  3. \n

    free-standing cookers; and<\/p>\n<\/li>\n

  4. \n

    independent boilers.<\/p>\n<\/li>\n<\/ol>\n

    The standard also specifies the procedures to be followed for on-site testing of the installations.<\/p>\n

    \n

    NOTE Where manufacturers\u2019 installation instructions are more onerous and give a higher level of safety, these take precedence over the requirements of this British Standard.<\/p>\n<\/blockquote>\n
