    Abstract - (Show below) - (Hide below)

    Provides detailed requirements, including safety and performance requirements and methods of test, for indirect gas fired forced convection air heaters having heat inputs greater than 330 kW but not exceeding 2 MW, intended for industrial and commercial applications.

    Scope - (Show below) - (Hide below)

    This British Standard specifies detailed requirements, including safety and performance requirements and methods of test, for indirect gas fired forced convection air heaters having heat inputs greater than 330 kW but not exceeding 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 indirect gas fired forced convection air heaters for use both with and without ducting, and intended primarily for space heating applications.

    This standard also specifies the requirements for indirect gas fired forced convection air heaters designed for permanent outdoor installation.

    It applies to appliances designed to operate on normal low pressure district supplies of 2nd family gas.

    For appliances fitted with gas boosters and/or flue dampers, additional requirements may apply.

    This standard does not apply to portable and transportable indirect gas fired forced convection air heaters.
