Chimneys - Concrete System Chimneys - Part 2: Balanced flue applications
This European Standard specifies the materials, dimensional and performance requirements for straight concrete system chimneys for balanced flue applications comprising a concrete flue liner and a combustion air supply duct, and a combination of compatible chimney components, which may be concrete flue blocks (see clause 4), obtained or specified from one manufacturing source with product responsibility for the whole chimney.
The standard does not apply to concrete system chimneys with back ventilation.
This standard does not cover products designated wet (W) in conjunction with corrosion class 3.
This European Standard also applies to concrete system chimneys constructed from storey-height elements and flue blocks reinforced for handling.
NOTE Any reference to the term flue blocks implies both flue blocks and their fittings, except where otherwise indicated.

European foreword This document (EN 16497-2:2017) has been prepared by Technical Committee CEN/TC 166 “Chimneys”, the secretariat of which is held by ASI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2017, and conflicting national standards shall be withdrawn at the latest by December 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document. In this European Standard, the Annexes A, C and D are normative (not forming part of the product specification) and Annexes E and ZA are informative. This standard is one of a series of coordinated standards dealing with specification, design, and testing of chimneys, both single and multi wall. The coordinated package of standards is further divided by material of construction and this European Standard is one of a series of specifications and execution documents dealing with design and installation of concrete chimney products and systems. The standards in this series for concrete chimney products and systems are: EN 1857, Chimneys — Components — Concrete flue liners; EN 1858, Chimneys — Components — Concrete flue blocks; EN 12446, Chimneys — Components — Concrete outer wall elements.
