CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this Europe an Standard the status of a national standard without any alteration. Up to date lists and bibliographical references concerning s uch national standards may be obtained on application to the Management Centre or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by tra nslation under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official versions.

Heating systems also include the effect of attached systems such as hot water production systems. All these standards are system standards, i.e. they are based on requirements addressed to the system as a whole and not dealing with requirements to the products within the system. Where possible, reference is made to other CEN or ISO standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed.EN 12170:2002 (E) 4 (intended blank page)EN 12170:2002 (E) 5 Introduction This European Standard is intended to be used in the preparation of documents for operation, maintenance and use of heating systems for new projects and renovation projects as well as in the updating of existing such documents. Documents for operation, maintenance and use are hereafter termed OM - system designers (as guidance when preparing their part of the OM - manufacturers (as guidance when establishing the OM - installers and commissioning personnel (as guidance when preparing their part of the OM - commissioning engineers (as guidance when verifying conformity with OM - owners (as guidance when specifying the requirements for the OM - safety arrangements, including air supply; - district heating heat exchangers, heat meters and primary domestic hot water production facilities; - energy sources, storage and supply; - flue gas systems, including condensate treatment and disposal; - heat distribution network, including associated components;EN 12170:2002 (E) 6 - heat emitters, including accessories; - systems for control and supervision; - water treatments and procedures (e.g. chemical and physical, including antifreeze). 2 Terms, definitions and abbreviations For the purposes of this European Standard, the following terms and definitions apply. 2.1 operation those actions necessary to make available the services, which the system has been designed to provide 2.2 maintenance combination of all technical, administrative and managing actions necessary to retain an item in, or restore it to, a state in which it can perform an intended function 2.3 use action of receiving the services, which the system has been designed to provide 2.4 item any part, component, device, sub system, functional unit, equipment or system that can be individually considered NOTE 1 Any item may consist of hardware, software or both, and may also in particular cases include people.
