This document describes the method of specifying the design, installation and labelling criteria for system chimneys, construction of custom-built chimneys, the relining of existing chimneys and connecting flue pipes for non-room sealed combustion appliances as well as the use of chimney products. It also gives information on commissioning of an installed chimney. This document applies to chimneys which are subject to the following limiting conditions: – the distance between the supports not to exceed 4 m; – the distance above the last structural attachment not to exceed 3 m; – the free-standing height above the uppermost structural support attachment for chimneys with rectangular cross section is not more than five times the smallest external dimension. The methods in this part of this document are applicable to chimneys and connecting flue pipes for non-room sealed combustion appliances. The methods in Part 2 of this document are applicable to chimneys and connecting flue pipes for room sealed combustion appliances.
