27、d heating applications meaning the combination of flue duct and air supply duct needed for the correct functioning of a C6roomsealed appliance. The current requirements and test methods apply to balanced flue type applications. Requirements and test methods for other roomsealed applications will fol

28、low in separate documents. A standard covering the design, installation and commissioning of room sealed heating applications is in the current CEN/TC 166 work program, which includes this Part 1: Vertical Terminals for C6-type appliances, and Part 2: Flue and air supply ducts for individual roomsea

29、led 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 flue ducts for C62- and C63-type gas appliances, which convey air for combustion, and the products of combustion from appliances to the outside

30、atmosphere. It also specifies the requirements for marking, manufacturers instructions, product information and evaluation of conformity. NOTE The classification of gas appliances is according to CEN/TR 1749. 2 Normative references The following referenced documents are indispensable for the applica
