Scope:

These requirements cover the design and construction of Type L vents intended for the venting of flue gases having temperatures not exceeding 300 °C. They may also be used where Type B gas vents are used. They are intended for installation in buildings to provide a passageway for conveying flue gases to the outer air. These requirements are also intended to cover the investigation of Pellet vents for use in residential dwellings for the venting to the outdoors of the products of combustion from particulate-fuelled space heaters.
