BS 6798:2009 specifies requirements for the selection, installation, inspection, commissioning and maintenance of gas‑fired boilers for central heating and other purposes, which have a total rated heat input not exceeding 70 kW, based on net calorific value. This includes cookers with integral boilers used to provide central heating.

It applies to boilers utilizing 1st, 2nd or 3rd family gases designed to operate in the condensing or non‑condensing mode for the heating of domestic dwellings or domestic dwellings in commercial premises by the circulation of heated water in open or closed systems. It applies both to boilers which carry a CE mark and also to previously used boilers which do not carry the CE mark.

BS 6798 gives recommendations on:

Selection of equipment and pre‑installation
Installation
Post‑installation.

In line with BS 5440-1 , this revision has acknowledged that European work on chimney standards has brought about the need in British
Standards to redefine chimney concepts and adopt common terminology consistent with the range of products used across the whole European community where a chimney is treated as a structure containing a flue (the passageway) and might include a liner (inner wall), insulation and an outer wall. The common terminology in UK industry, which has regarded a chimney as a masonry structure generally associated with solid fuel appliances, has been superseded.

BS 6798:2009 supersedes BS 6798:2000, which is withdrawn.
