This part of BS 8660 specifies requirements for the selection, installation, inspection, commissioning, servicing and maintenance of room-sealed gas-fired Stirling engine micro-cogeneration appliances and their protection devices designed to operate in parallel with public low-voltage distribution networks.
NOTE 1 Sometimes micro-cogeneration appliances are referred to as small-scale embedded 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:
is rated up to and including 16 A per phase, single or multiphase 230/400 V a.c.;
has a total rated heat input not exceeding 70 kW, based on net calorific value;
utilizes 1st, 2nd or 3rd family gases and is designed to operate in the condensing mode for the heating of domestic dwellings, including domestic dwellings in commercial premises, by the circulation of heated water in open or closed systems;
has been shown to meet the type verification tests in the appropriate annex of Engineering Recommendation G83/1/1;
carries a CE mark (see 6.2.1).
This standard does not apply to:
micro-cogeneration appliances with a rated input of over 70 kW;
groups of micro-cogeneration appliances with individual ratings of less than 70 kW with an aggregate input of greater than 70 kW.
NOTE 3 Groups of micro-cogeneration appliances with individual ratings of less than 70 kW, but with a maximum aggregate input of ≤70 kW, may be installed to this standard but specialist advice on the system design, installation and control needs to be sought from the appliance manufacturer.
It is not applicable to the detailed design and installation of the whole heating system, which is specified in BS EN 12828:2003 (incorporating corrigendum January 2009), BS EN 12831:2003 (incorporating corrigendum January 2009) and BS 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NOTE 4 With the publication of BS EN 12828, BS EN 12831 and BS EN 14336, BS 5449 has been withdrawn.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 and installation practices; they cover commercial as well as domestic heating systems and exclude hot water. Consequently, these standards include national annexes covering all the relevant material from BS 5449.
NOTE 5 In this standard, heat input is expressed in terms of net calorific values (CV), unless stated otherwise. The ratio of gross to net heat input is approximately 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 any micro-cogeneration appliances are competent to do so. Clause 4 gives information on competence.
