These changes, which apply only to England*, update the guidance on materials and workmanship. The provisions for flue outlet clearances relative to adjacent pitched roofs have been clarified in Diagram 17.

3 The guidance on the provision of hearths and wall clearances for solid fuel appliances have been made more flexible to take account of the availability of modern appliances . Section 2, 3 & 4. The guidance for permanent ventilation openings for open flued appliances in very airtight houses (those with a design air permeability less than or equal to m3/( )) have been increased to counteract the decrease in adventitious ventilation relative to older houses. Appendix F gives advice on assessing the air permeability of older houses in relation to this guidance. Section 4. This section now explicitly includes liquid biofuel and blends on mineral oil and liquid biofuel within the scope of Combustion installations designed to burn oil. Section 5.

4 The guidance on identifying where secondary containment for oil tanks is necessary has been expanded to include locations in inner protection zone as shown on the Environment Agency's groundwater sources map. Appendix G. This informative appendix provides and explanation of the European designation system for certain flue and chimney products. * This approved document gives guidance for compliance with the Building Regulations for Building work carried out in England.
