BS EN 14989-2:2007EN 14989-2:2007 (E) 6 Introduction This European Standard covers flue and air supply ducts for room sealed appliances meaning the combination of chimney an
31、d air supply duct needed for the correct functioning of a room sealed appliance. The requirements in this European Standard have been drawn up in connection with the widespread use of so-called room sealed appliances in which the combustion air supply duct and flue duct may be separate or as a conce
32、ntric configuration. The requirements for flue ducts for separate air/flue configurations are in EN 1856-1. The requirements for terminals for room sealed appliances type C62 and C63 are covered by EN 14989-1. BS EN 14989-2:2007EN 14989-2:2007 (E) 7 1 Scope This European Standard specifies requireme
