It must be possible to clean flue systems easily and safely. It must be
possible:
• to check the cross-section and tightness of the pipework.
• to check the required cross-section between the flue and duct
(secondary ventilation) for safe operation of the combustion system,
and to clean it.
▶ Observe local standards and regulations.
