Chimneys. Requirements and test methods for metal chimneys and material independent air supply ducts for roomsealed heating applications - Vertical air/flue terminals for C6-type appliances Ingestion-build-52208 BS EN ISO 9001 andBS EN 14989 1: 2007 covers vertical air flue terminals with metal flue ducts for chimneys for roomsealed heating applications meaning the combination of flue duct and air supply duct needed for the correct functioning of a C6 roomsealed appliance. BS EN 14989 1 specifies the requirements and test methods for positive pressure air flue terminals with metal flue ducts for C62 and C63 type gas appliances, which convey air for combustion, and the products
