Building Regulations BUILDING REGULATIONS The basic requirements for the design and construction of chimneys in England and Wales are given in The Approved Document to the Building Regulations 2000 - Part J : 2002 Edition - Combustion appliances and fuel storage systems. In Scotland, the necessary requirements are laid down in Part F of the Building Standards (Scotland) and several deemed-to-satisfy examples are provided. In Northern Ireland the requirements are given in Technical Booklet L of the Building Regulations (Northern Ireland) 1990, published by the Department of the Environment for Northern Ireland. The Building Regulations have key requirements for heat producing appliances and chimneys: •That there is an adequate supply of air. •That the products of combustion are safely discharged to the outside air. •That the building is protected from catching fire. •That a check list detailing the construction of the chimney should be completed see Annex A. •That a notice plate detailing the correct application and use of the chimney should be attached within the building see Annex A. STANDARDS AND CODE OF PRACTICE Flue liners should be specified to the requirements of the European Standard, BS EN 1457:1999 A1:2002 – Chimneys – Clay/ceramic flue liners – Requirements and test methods. Flue terminals are specified in BS EN 13502:2002 - Clay/ceramic flue terminals – Requirements and test methods. The standards give the relevant details of dimensions and tolerances, performance requirements, sampling procedures, testing and marking. The construction of chimneys using clay flue liners is detailed in BS 6461: Part 1: 1984 - Installation of chimneys and flues for domestic appliances burning solid fuel (including wood and peat) Part 1 - Code of practice for masonry chimneys & flue pipes. MARKING Clay flue liners to BS EN 1457 are marked with the number of the standard EN 1457, the manufacturer‘s identification, the date of manufacture and their relevant class number e.g. A1 N1. They also will be stamped with the C.E. if CE certification has been achieved. Clay terminals to BS EN 13502: 2002 are marked with the number of the standard EN 13502, the manufacturer‘s identification and the date of manufacture, nominal size, nominal height and type of restricted terminal (if appropriate). They will also be stamped with the CE mark where this has been achieved.
