Chimneys - System chimneys with plastic flue liners - Requirements and test methods

This European Standard specifies the performance requirements and test methods for system chimneys with plastic flue liners used to convey the products of combustion from appliances to the outside atmosphere under dry and wet conditions. It also specifies the requirements for marking, manufacturer's instructions and evaluation of conformity. This European Standard describes chimney components from which system chimneys can be assembled. This European Standard is not applicable to chimneys with sootfire resistance classification class G. This European Standard is not applicable for chimneys with the following classification: - corrosion resistance class 2 concerning natural wood ); - corrosion resistance class 3; - pressure class N2. This European Standard is applicable to chimneys designed so that no condensate accumulation can occur, e.g. with a minimum inclination of 3° to the horizontal. This European Standard is not applicable - for system chimneys with plastic coated flue liners; - to structurally independent (free-standing or self-supporting) chimneys. Chimneys with components which need further processing during the installation to reach the final material properties are no system chimneys and therefore also not covered by this standard. This European Standard does not cover the requirements for horizontal terminals (as defined for C1 installation types in CEN/TR 1749) regarding aerodynamic behaviour, rainwater ingress and icing behaviour.

Overview

EN 14471:2013/FprA1 is a European standard developed by the European Committee for Standardization (CEN) that specifies the performance requirements and test methods for system chimneys with plastic flue liners. These chimneys are designed to safely convey combustion products from various appliances to the outside atmosphere under both dry and wet conditions. The standard also covers marking requirements, manufacturer’s instructions, and conformity evaluation to ensure quality and safety compliance.

This standard applies specifically to system chimneys assembled from standardized chimney components featuring plastic flue liners. However, it excludes chimneys with sootfire resistance classification class G, certain corrosion resistance and pressure classification levels, as well as chimneys with condensate accumulation or plastic coated liners. It is not applicable to free-standing or self-supporting chimneys that are structurally independent.

Key Topics

The standard focuses on several core technical and performance areas to ensure reliable chimney function:

• Material and Component Requirements
  Specifies the materials and components suitable for use in plastic flue liner chimneys, with emphasis on resistance to chemical corrosion, UV exposure, thermal loads, and condensation.

• Mechanical and Thermal Load Testing
  Defines test methods to evaluate resistance to mechanical stresses, wind loads, and long-term thermal exposure to replicate real-life operating conditions.

• Gas Tightness and Rainwater Penetration
  Establishes procedures to test gas tightness to prevent leaks and methods to resist rainwater ingress, ensuring chimney integrity and safety for external installation.

• Fire Resistance and Sootfire Safety
  Sets thermal resistance classifications necessary to withstand typical chimney operating temperatures, including sootfire resistance within defined classes.

• Marking and Documentation
  Requires clear CE marking, manufacturer identification, and comprehensive Declaration of Performance (DoP), facilitating traceability and compliance with EU regulations.

• Exclusions and Scope Limitations
  Clarifies that chimneys with certain pressure classes (e.g., N2), corrosion resistance levels, or free-standing designs fall outside this standard’s scope.

Applications

EN 14471:2013/FprA1 is directly applicable to:

• Residential and Commercial Heating Installations
  Including wood, gas, and oil-burning appliances where plastic flue liners are used within system chimneys to safely convey exhaust gases.

• Prefab Chimney Assemblies
  System chimneys assembled from standardized plastic-lined components used in building construction, renovation, or retrofit projects.

• Manufacturers and Installers
  Provides manufacturers with harmonized requirements for designing and testing chimney components and offers guidance for installers regarding proper system assembly.

• Regulatory Compliance
  Enables compliance with EU Construction Products Regulation (CPR) and harmonized standards required for placing chimney systems on the European market.

Related Standards

For a fully compliant system and holistic safety approach, EN 14471:2013/FprA1 works in conjunction with:

• EN 13384-1: Chimneys - Design and calculation of chimneys - Part 1: Chimney shafts
  Supports dimensioning and flow resistance evaluation for chimney sections and fittings.

• CEN/TR 1749: Technical Report on chimney terminal types and their aerodynamic, rainwater, and icing behaviors - though horizontal terminals are excluded from EN 14471’s scope.

• Construction Products Regulation (Regulation (EU) No 305/2011)
  Mandates harmonized assessment and declaration of performance (AVCP) systems and CE marking for construction products like chimneys.

By applying EN 14471:2013/FprA1, manufacturers and building professionals can ensure safe, durable, and efficient installation of plastic flue liner chimneys that meet strict European safety and performance standards. This boosts confidence in product quality and facilitates smoother market acceptance across the EU.
