适用范围：This British Standard specifies requirements for the installation, including design, inspection, commissioning and maintenance, of gas-fired hot water boilers of net rated heat inputs exceeding 70 kW but not exceeding a net heat input of 1.8 MW. Groups of boilers with individual net heat inputs of 70 kW or less, but with aggregate net heat inputs in excess of 70 kW, are also covered.This British Standard is applicable to the installation of boilers that are designed to utilize normally distributed gases of Group H of the second family (e.g. natural gas), and gases of Group P (e.g. propane) and Group B (e.g. butane) of the third family. For the purposes of this installation standard, LPG/air mixtures are regarded as third family gases.This British Standard is applicable to the installation of the following gas-fired hot water boilers:Boilers supplied as a complete assembly and conforming to BS EN 656 or BS 5978 (all parts); Boilers supplied as a complete assembly and used in multiple boiler installations where the total net heat input exceeds 70 kW and conforming to BS EN 297, BS EN 483 or BS EN 677; Boilers and burners delivered separately and assembled on site, comprising: 1) a boiler shell conforming to BS EN 303-1, BS EN 12952 (all parts), BS EN 12953 (all parts), BS 779, BS 855 or BS 2790; 2) a burner conforming to BS EN 676; 3) an assembly conforming to BS EN 303-3 or BS 5987-1 and BS 5978-3.
