Installation requirements for direct and indirect gas-fired forced convection air heaters for commercial and industrial space heating.
This British Standard specifies the installation requirements for direct and indirect gas-fired forced convection air heaters for space heating that are designed for commercial or industrial applications and to which the Gas Appliances (Safety) Regulations 1995 apply.
This standard applies to the installation of appliances that are designed to utilize gases of Group H of the second family (e.g. natural gas), gases of group P of the third family (e.g. propane) as well as gases of group B of the third family (e.g. butane) when supplied under the conditions of the third family pressure couple.
This standard also applies to air heaters designed to supply make-up air, door curtain heaters and transportable air heaters. It also covers installation of heaters in areas where petroleum or other flammable heavier-than-air vapours can be present.
It does not include the safety requirements for installation where flammable dusts, toxic gases or flammable lighter-than-air gases might be present in significant quantities.
This standard does not apply to the installation of air heaters to which the Gas Appliances (Safety) Regulations 1995 do not apply, or that are designed for use in domestic premises.
