This British Standard specifies constructional, dimensional and performance requirements for inset open fires designed to burn solid mineral fuels (i.e. bituminous coal, Welsh dry steam coal, anthracite or manufactured fuels derived from these coals). It does not apply to inset open fires designed to give space heating by convection (see BS 3376).
This standard covers appliances of nominal widths 350 mm, 400 mm, 450 mm and 500 mm, designed for use either with fireplace components complying with BS 1251 and installed in accordance with BS 8303, or with special fireplace components or boilers supplied with the appliance.
The essential components of appliances covered by this standard are the firefront, bottomgrate, ashpit cover, ashpan and means of primary air control.
Specified optional features comprise a deepening bar, deepening plate, front firebars, undergrate gas igniter and boiler.
Appliances are designated as either intermittent or overnight.
