Introduction
CEN/TC 166 started with its programme on standardization of chimneys approximately 30 years ago,
with standards for interfaces, for products, for tests and last but not least for design, installation,
construction and commissioning matters.
In the last years, first priority in the work program was given to product and test standards.
In the meantime, most of the product and test standards were published or are nearly ready for
publication. In order to introduce the products in a simple way on the markets of the different Member
States, some common rules for design, installation, and commissioning especially with reference to the
designation of a chimney were considered helpful.
Initially, CEN/TC 166/SC 2 started the work on execution standards for metal chimneys, the first
standard being EN 12391-1 in 2003.
In order not to repeat this work in all material orientated WGs and SCs, CEN/TC 166 decided in 2002 to
give the task to WG 1 to develop a material independent design, installation and commissioning standard.
CEN/TC 166/WG 1 started the work in 2003 and decided first to draft two documents, one for chimneys
connected to non-room sealed combustion appliances and one for chimneys connected to room sealed
combustion appliances.
Application of this document presupposes awareness of applicable legal requirements in the different
CEN Member States and its affiliates. In CEN Member States and its affiliates where no applicable legal
requirements exist, this document provides guidance for the design, installation and commissioning of
chimneys.
NOTE Where “Member States” is mentioned in this document this also includes affiliates.
1 Scope
This document describes the method of specifying the design, installation and labelling criteria for
chimney systems, construction of custom-built chimneys, the relining or converting of existing chimneys,
connecting flue pipes and air supply pipes for room sealed combustion appliances as well as the use of
chimney products. It also gives information on commissioning of an installed chimney.
This document applies to chimneys which are subject to the following limiting conditions:
— the distance between the supports not to exceed 4 m;
— the distance above the last structural attachment not to exceed 3 m;
— the free-standing height above the uppermost structural support attachment for chimneys with
rectangular cross section is not more than five times the smallest external dimension.
This document does not cover:
— chimneys which serve a mixture of fan assisted or forced draught burners or natural draught
appliances;
— installations having a configuration of the type C .
NOTE Room sealed gas appliances are classified as type C according to EN 1749.
The methods in this part of this document are applicable to chimneys and connecting flue pipes for room
sealed combustion appliances. The methods in Part 1 of this document are applicable to chimneys and
connecting flue pipes for non-room sealed combustion appliances.

4 Design
4.1 General
In order to design a chimney, the following steps should be followed to achieve a safe chimney.
Specify whether the chimney design is for a single combustion appliance or multiple combustion
appliance application. Specify the type of multiple combustion appliance configuration, i.e. whether
cascade or multiple inlet.
The design shall specify whether the chimney configuration to be installed shall comprise two concentric
or separate ducts.
NOTE Where a chimney is approved together with the combustion appliance, the information for flue sizing or
the designation parameters not associated with the installation aspects are not necessary as the combination of
combustion appliance and chimney has been certificated together.
4.2 Characteristics
4.2.1 Designation of an installed chimney
In order to identify the characteristics of the chimney the installed chimney shall be designated.
The designation shall include information on the temperature class, the pressure class, the condensate
resistance class, the corrosion resistance class and the sootfire resistance class and where appropriate
the minimum distance to combustible material.
The meaning of the listed characteristics corresponds to the product characteristics of system chimneys
and components for chimneys such as flue liners, connecting flue pipes and accessories.

Introduction
CEN/TC 166 started with its programme on standardization of chimneys approximately 30 years ago,
with standards for interfaces, for products, for tests and last but not least for design, installation,
construction and commissioning matters.
In the last years, first priority in the work program was given to product and test standards.
In the meantime, most of the product and test standards were published or are nearly ready for
publication. In order to introduce the products in a simple way on the markets of the different Member
States, some common rules for design, installation, and commissioning especially with reference to the
designation of a chimney were considered helpful.
Initially, CEN/TC 166/SC 2 started the work on execution standards for metal chimneys, the first
standard being EN 12391-1 in 2003.
In order not to repeat this work in all material orientated WGs and SCs, CEN/TC 166 decided in 2002 to
give the task to WG 1 to develop a material independent design, installation and commissioning standard.
CEN/TC 166/WG 1 started the work in 2003 and decided first to draft two documents, one for chimneys
connected to non-room sealed combustion appliances and one for chimneys connected to room sealed
combustion appliances.
Application of this document presupposes awareness of applicable legal requirements in the different
CEN Member States and its affiliates. In CEN Member States and its affiliates where no applicable legal
requirements exist, this document provides guidance for the design, installation and commissioning of
chimneys.
NOTE Where “Member States” is mentioned in this document this also includes affiliates.
1 Scope
This document describes the method of specifying the design, installation and labelling criteria for
chimney systems, construction of custom-built chimneys, the relining or converting of existing chimneys,
connecting flue pipes and air supply pipes for room sealed combustion appliances as well as the use of
chimney products. It also gives information on commissioning of an installed chimney.
This document applies to chimneys which are subject to the following limiting conditions:
— the distance between the supports not to exceed 4 m;
— the distance above the last structural attachment not to exceed 3 m;
— the free-standing height above the uppermost structural support attachment for chimneys with
rectangular cross section is not more than five times the smallest external dimension.
This document does not cover:
— chimneys which serve a mixture of fan assisted or forced draught burners or natural draught
appliances;
— installations having a configuration of the type C .
NOTE Room sealed gas appliances are classified as type C according to EN 1749.
The methods in this part of this document are applicable to chimneys and connecting flue pipes for room
sealed combustion appliances. The methods in Part 1 of this document are applicable to chimneys and
connecting flue pipes for non-room sealed combustion appliances.

In order to design a chimney, the following steps should be followed to achieve a safe chimney.
Specify whether the chimney design is for a single combustion appliance or multiple combustion
appliance application. Specify the type of multiple combustion appliance configuration, i.e. whether
cascade or multiple inlet.
The design shall specify whether the chimney configuration to be installed shall comprise two concentric
or separate ducts.
NOTE Where a chimney is approved together with the combustion appliance, the information for flue sizing or
the designation parameters not associated with the installation aspects are not necessary as the combination of
combustion appliance and chimney has been certificated together.
