This British Standard gives detailed requirements, including safety and performance requirements and methods of test, for direct gas fired forced convection air heaters having heat inputs up to 2 MW, intended for industrial and commercial applications. Appliances covered by this standard are not intended for installation in domestic dwellings. The scope of this standard includes direct gas fired forced convection air heaters for use both with and without ducting, and intended primarily for space heating applications. It therefore includes air heaters designed to provide make-up air, door curtain heaters, spray booth heaters, portable air heaters and direct fired air heaters capable of providing full space heating. This standard specifies the requirements for direct gas fired forced convection air heaters designed for permanent outdoor installation. It also specifies the requirements for transportable direct gas fired forced convection air heaters. This standard applies to appliances designed to operate on normal low pressure district supplies of 2nd family gas. For appliances fitted with gas boosters, additional requirements may apply. NOTE. The titles of the publications referred to in this standard are listed on the inside back cover.
