It was prepared by Panel GSE/30/-/5, Boilers of rated inputnot exceeding 70kW and hot water supply, under the authority of TechnicalCommittee GSE/30, Gas installations (1st, 2nd and 3rd family gases). A list oforganizations represented on this committee

14、ty (the general requirementsfor which are specified in BS EN 1443) where a chimney is treated as a structurecontaining a flue (the passageway) and possibly a liner (inner wall), insulationand an outer wall. The common terminology in UK industry, which has regardeda chimney as a masonry structure gen

15、erally associated with solid fuel appliances,has been superseded.Use of this documentThe requirements of this specification are supported by commentary, often inthe form of recommendations. To comply with this specification, it is necessaryto comply with all its requirements. The operative may depar

23、111 ScopeThis part of BS 8660 specifies requirements for the selection, installation,inspection, commissioning, servicing and maintenance of room-sealed gas-firedStirling engine micro-cogeneration appliances and their protection devicesdesigned to operate in parallel with public low-voltage distribu

24、tion networks.NOTE 1 Sometimes micro-cogeneration appliances are referred to as small-scaleembedded generators (SSEG), e.g. in Engineering Recommendation G83/1/1.NOTE 2 A room-sealed appliance is designated as Type C in PD CEN/TR 1749.The term “micro-cogeneration appliance” refers to equipment that:

25、 is rated up to and including 16 A per phase, single ormultiphase 230/400 V a.c.; has a total rated heat input not exceeding 70 kW, based on net calorificvalue; utilizes 1st, 2nd or 3rd family gases and is designed to operate in thecondensing mode for the heating of domestic dwellings, including dom

26、esticdwellings in commercial premises, by the circulation of heated water inopen or closed systems; has been shown to meet the type verification tests in the appropriate annexof Engineering Recommendation G83/1/1; carries a CE mark (see 6.2.1).This standard does not apply to: micro-cogeneration appl

27、iances with a rated input of over 70 kW; groups of micro-cogeneration appliances with individual ratings of lessthan 70 kW with an aggregate input of greater than 70 kW.NOTE 3 Groups of micro-cogeneration appliances with individual ratings of lessthan 70 kW, but with a maximum aggregate input of 70

28、kW, may be installed tothis standard but specialist advice on the system design, installation and controlneeds to be sought from the appliance manufacturer.It is not applicable to the detailed design and installation of the whole heatingsystem, which is specified in BS EN 12828:2003 (incorporating c

29、orrigendumJanuary 2009), BS EN 12831:2003 (incorporating corrigendum January 2009) andBS EN 14336:2004 (incorporating corrigendum January 2009).NOTE 4 With the publication of BS EN 12828, BS EN 12831 and BS EN 14336,BS 5449 has been withdrawn. These standards are not aligned to UK design andinstalla

30、tion practices; they cover commercial as well as domestic heating systems andexclude hot water. Consequently, these standards include national annexes coveringall the relevant material from BS 5449.NOTE 5 In this standard, heat input is expressed in terms of net calorific values(CV), unless stated o

31、therwise. The ratio of gross to net heat input isapproximately 1.11:1 for natural gas, 1.09:1 for propane, and 1.08:1 for butane.NOTE 6 It is essential that persons carrying out the installation of anymicro-cogeneration appliances are competent to do so. Clause 4 gives informationon competence.BRITI
