26、ed Kingdom. EN 14989-1:2007 (E) 5 Introduction This standard 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 C6roomsealed appliance. The current

27、requirements and test methods apply to balanced flue type applications. Requirements and test methods for other roomsealed applications will follow in separate documents. A standard covering the design, installation and commissioning of room sealed heating applications is in the current CEN/TC 166 w

28、ork program, which includes this Part 1: Vertical Terminals for C6-type appliances, and Part 2: Flue and air supply ducts for individual roomsealed appliances. EN 14989-1:2007 (E) 6 1 Scope This standard specifies the requirements and test methods for positive pressure air/flue terminals with metal

29、flue ducts for C62- and C63-type gas appliances, which convey air for combustion, and the products of combustion from appliances to the outside atmosphere. It also specifies the requirements for marking, manufacturers instructions, product information and evaluation of conformity. NOTE The classific

30、ation of gas appliances is according to CEN/TR 1749. 2 Normative references The following referenced documents are indispensable for the application of this document.
