The installation of wood-burning stoves and chimney systems must follow wood burning stove building regulations. The regulations are in place to guide the installer with the installation and system design of the wood burning stove. Part J of the regulation titled ‘Combustion appliances and fuel storage systems’ covers the installation of wood burning stoves. Document J contains 4 requirements that need to be met when installing wood burning stoves and chimney systems; these are J1, J2, J3, and J4.
Wood Burning Stove Building Regulations – Requirements:
J1 ‘Air Supply’. This covers the importance of having a good air supply to the wood- burning stove. This prevents overheating and also explains general efficiency of the flue and how it should be maintained.
J2 ‘Discharge of Products of Combustion’. This expands into the importance of being able to make sure that the products of combustion have an adequate outlet to the outside air. Most new wood burning stoves do not emit much in the way of smoke and we will touch on clean burn technology in another article soon.
J3, ‘Protection of the building’. Wood burning stoves with chimney systems and fireplaces with chimneys need to be designed and installed so that there is minimal risk to the building. All manufacturers of wood burning stoves and chimney systems have their own standards relating to each product. If it is greater than that stated in the building regulation then this should be followed. Wood burning stove and chimney systems get extremely hot and so a safe distance must be kept from anything combustible.
J4, ‘Provision of information’. This provision relates to having a durable notice near the wood burning stove or chimney system once it has been installed. Anyone who has to come in contact with it in the future for maybe service or maintenance, will be able to have access to detailed information about the installation.
Official, approved documents are intended to be a guide to help with the installation of the wood burning stove and chimney system. However, there may be alternative approaches that also achieve the end goal. The ultimate responsibility of the installation of the wood burning stove and chimney system is with the installer. If the installer can demonstrate an alternative method appropriately whilst adhering to the wood burning stove building regulations, using correct channels, alternate methods can be used.
