The manual is designed to be used alongside Document J of the Building Regulations England & Wales (stoves without boilers) and Document G of the Building Regulations England & Wales (stoves with boilers) coupled with any advice provided by your local Building Control. Note that regulations for Scotland and Northern Ireland differ slightly and precise details should be checked for compliance. Other regulations may be applicable (e.g. for electrics if adding controls to wet systems). In all cases you should not rely on this manual alone.
