Single wall flue when used inside a building must be kept well away from any inflammable materials. This must at least 3 times its diameter. A 6” (150mm) single wall flue pipe must be 18” (450mm). This often means that twin wall flue is more suitable as it can be as close as 2-3” from inflammables, depending on the manufacture.
Good access for cleaning should always be designed into the chimney system.
If fitted with a fan flue it is recommended to connect from a 45deg or 90deg angle through a Tee pipe.
