Document ‘J’ is the building regulation for the installations of stoves, flues and open fires. These regulations must be adhered to not only for a correct ‘sign off’ of the installation but also to make sure certain issues are addressed that help the stove to perform correctly.
A very important part of the building regulations is that you must fit the stove according to the manufacturers instructions – these override building regulations.
Your HETAS installation certificate is proof that your work has been carried out to the correct regulations. Without this you may have difficulties when selling the property and your house insurance may become invalid.
