Chimneys & flues
an air gap between the walls of the inner and outer blocks. The air gap combined with the natural insulating properties of pumice provide effective insulation along the length of the chimney and maintaining the flue gas temperature will enable the flue gases to freely escape to the atmosphere.
UKCA marking
The UKCA mark will be mandatory in Great Britain from 1st January, 2023, replacing the CE mark. In Northern Ireland the CE mark will still be required because of Brexit regulations. The UKCA mark confirms that the flue meets all the relevant chimney
standards and has been tested in accordance with these standards. Chimneys and flues are required to discharge a variety of combustion gases and different types of flue will be required to safely handle the different gases. Linked to the UKCA and CE mark is a user-readable classification system that designates the features of the flue components. The features covered include temperature and pressure rating, fire, condensate, corrosion resistance and distance to combustibles. With stainless steel components, a label showing the classification must go with each flue component so that it’s specification can be easily verified. The UKCA mark applies to both flue components and to system chimneys. It is worth pointing out that a CE/UKCA mark for a system chimney applies to the complete flue system, including add on components like rain caps. The use of components that have not been tested with the flue invalidates the CE/UKCA mark and turns the system chimney into a custom flue.
The BFCMA is a UK Trade Association representing the chimney and flue industry and works closely with Government, public bodies and other organisations to further the interest of the chimney and flue industry. It represents the majority of manufacturers and sole distributors in the industry.
