33、rs flue and air supply ducts for room sealed appliances meaning the combination of chimney and 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 a

34、ppliances in which the combustion air supply duct and flue duct may be separate or as a concentric 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-

36、It also specifies the requirements for marking, manufacturers instruction, product information and evaluation of conformity. NOTE 1 Recommendations for preferred dimensions of products are given in the informative Annex A. NOTE 2 In this European Standard, only general requirements are specified for

37、 elastomeric and plastic components. Elastomeric and plastic products used in flue systems are covered by separate standards, i.e. EN 14241-1 and EN 14471. 2 Normative references The following referenced documents are indispensable for the application of this document.
