This part of BS 5410 gives recommendations and guidance on the design, installation, commissioning and maintenance of liquid fuel firing installations for heating, hot water and steam supply services in non-domestic buildings. This also includes buildings containing multiple separate dwellings which are all served by a single heating and hot water system and buildings where public assembly, entertainment or hospitality take place.

This part of BS 5410 is applicable to installations burning liquid fuel conforming to BS 2869, and other equivalent fuels, including biofuels, for example, those containing fatty acid methyl esters (FAME) conforming to BS EN 14214, and blends thereof.

This British Standard covers the provision of new installations and also gives guidance on the modernizing of existing installations. This British Standard also gives recommendations and guidance on the selection and installation of liquid fuel storage tanks associated with these installations.

This part of BS 5410 is applicable to the liquid fuel firing equipment forming part of a multi-fuel installation in which liquid fuel is not burnt simultaneously with any other fuel. It is not applicable to liquid fuelled systems for marine installations.

This British Standard is intended for use by designers, specifiers, installers and building owners.
