Room heaters fired by solid fuel - Requirements and test methods

This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) instructions and marking together with associated test methods and test fuels for type testing residential roomheaters fired by solid fuel.
This Standard is applicable to non-mechanically fired appliances which are listed under categories 1a and 2a of Table 1. These appliances provide heat into the space where they are installed. Additionally, where fitted with a boiler, they also provide domestic hot water and/or central heating. These appliances may burn either solid mineral fuels, peat briquettes, natural or manufactured wood logs or be multi-fuel in accordance with the appliance manufacturer’s instructions.
This standard is not applicable to appliances with fan assisted combustion air.

Raumheizer für feste Brennstoffe - Anforderungen und Prüfungen

Diese Europäische Norm gilt für freistehende oder eingebaute Raumheizer für feste Brennstoffe, ohne funktionalen Änderungen, die mit Feuerraumtüren entweder geschlossen oder geschlossen und offen betrieben werden können und die in den Kategorien 1a und 2a in Tabelle 1 aufgeführt sind. Diese Europäische Norm ist nur für nicht mechanisch beschickte Feuerstätten der Kategorien 1a und 2a von Tabelle 1 anwendbar. Diese Europäische Norm beschreibt Anforderungen an Auslegung, Herstellung, Ausführung, Sicherheit und Leistungsvermögen (Wirkungsgrad und Emission) von Raumheizer für feste Brennstoffe (im Folgenden als "Feuerstätte(n)" bezeichnet) und deren Anleitungen. Weiterhin enthält diese Norm Festlegungen für die Konformitätsbewertung, das heißt Typprüfung (ITT) und werkseigene Produktionskontrolle (FCP) und die Kennzeichnung der Feuerstätten. Diese Feuerstätten beheizen den Aufstellungsraum. Sofern sie mit wasserführenden Bauteilen ausgestattet sind, liefern sie Heizwasser und/oder dienen der Zentralbeheizung. Diese Feuerstätten können entsprechend der Bedienungsanleitung des Herstellers entweder feste mineralische Brennstoffe, Torfbriketts, Holzscheite, Holzbriketts oder mehrere dieser Brennstoffe verfeuern. Diese Norm gilt nicht für Feuerstätten mit Verbrennungsluftgebläse oder mechanisch beschickte Feuerstätten.

Poêles à combustible solide - Exigences et méthodes d'essai

La présente Norme européenne est applicable aux poêles à combustible solide, indépendants ou encastrés, sans modification fonctionnelle, qui fonctionnent avec des portes foyères uniquement fermées, ou ouvertes et fermées, et qui sont énumérés sous les catégories 1a et 2a du Tableau 1. D'autre part, la présente Norme européenne n'est applicable qu'aux poêles dépourvus d’alimentation mécanique qui sont énumérés sous les catégories 1a et 2a du Tableau 1. La présente Norme européenne spécifie les exigences relatives à la conception, la fabrication, la construction, la sécurité et la performance (en termes de rendement et d'émission) des poêles à combustible solide (appelés ci-après « appareils ») et fournit des instructions les concernant. En outre, elle fournit des dispositions pour l'évaluation de la conformité, c'est-à-dire l'essai de type initial (ITT) et le contrôle de fabrication en usine (FPC) ainsi que pour le marquage de ces appareils. Ces appareils produisent de la chaleur dans l’espace où ils sont installés. De plus, lorsqu’ils sont équipés d’un bouilleur, ils produisent également de l’eau chaude à usage domestique et/ou du chauffage central. Ces appareils peuvent utiliser soit des combustibles minéraux solides, des briquettes de tourbe, des bûches de bois naturel ou reconstitué, soit plusieurs combustibles conformément aux instructions du fabricant. Cette norme ne s’applique pas aux appareils équipés d'un ventilateur pour l'alimentation en air de combustion ou aux appareils à alimentation mécanique.

This European Standard is applicable to freestanding or inset roomheaters fired by solid fuel, without
functional modification, that operate with fire doors either as closed only or as closed or open and
which are listed under categories 1a and 2a of Table 1. This European Standard is also only
applicable to non-mechanically fired roomheaters as listed under categories 1a and 2a of Table 1.
This European Standard specifies requirements relating to the design, manufacture, construction,
safety and performance (efficiency and emission) of roomheaters fired by solid fuel (hereafter referred
to as “appliance(s)”) and provides instructions for them. Furthermore, it also gives provisions for
evaluation of conformity i.e. initial type testing (ITT) and factory production control (FPC) and marking

4.1 Production documentation
The type of appliance in accordance with Table 1 submitted for testing shall be stated and the
appliance shall be tested using the standard appropriate to that claim.
The parameters and characteristics considered in making the decisions in relation to either the family
or range of appliances to be submitted for initial type testing (see 8.2.1) shall be recorded. Where
changes are made to an appliance in the design, the raw material, the supplier of the components, or
in the production process, which would significantly alter the performance characteristics of the
appliance, especially in respect of one or more of the list of characteristics detailed in Table 9 and
Table 10, (see 8.2.2) these shall be recorded. A copy of the parameters and characteristics
considered in making the decisions shall be included in the production documentation for each
appliance.
To identify the appliance, related documents and/or scaled assembly drawings shall be available
showing the basic design and construction of the appliance. The documentation and/or the drawings
shall include at least the following information:
 the specification of the materials used in the construction of the appliance;
 the manufacturer’s declared nominal heat output in kW using fuels recommended by the
manufacturer together with the declared minimum refuelling intervals for these fuels.

oSIST prEN 13240:2011
prEN 13240:2011 (E)
If the appliance is fitted with a boiler, then the following additional details shall also be specified:
 the welding process used in the manufacture of the boiler shell;
NOTE The symbol for the type of weld used is sufficient.
 the permissible maximum operating water temperature, in °C;
 the permissible maximum operating pressure, in bar;
 the type test pressure, in bar;
 the water heating output, in kW.
4.2 Construction
4.2.1 General construction
4.2.1.1 Design, manufacture and assembly
The shape and dimensions of the components and equipment and the method of design and
manufacture and, if assembled on site, the method of assembly and installation, shall ensure that,
when operated as specified in accordance with the test procedures of this standard and exposed to
the associated mechanical, chemical and thermal stresses, the appliance shall operate reliably and
safely such that during normal operation no combustion gas posing a hazard can escape into the
room in which the appliance is installed nor can embers fall out. Non-combustible materials shall be
used, except that it shall be permissible to use combustible materials for the following applications:
 components or accessories fitted outside the appliance;
 internal components of controls and safety equipment;
 operating handles;
 electrical equipment.
No part of the appliance shall comprise any material known to be harmful.
When fired with solid mineral fuels, the appliance shall have a bottomgrate and an ashpan.
Component parts, which require periodic replacement and/or removal shall be either so designed or
marked for identification to ensure correct fitting.
NOTE 1 Because the entire heat dissipating surfaces of the appliance including the flue spigot/socket and the
flue gas connector are working surfaces, there is no requirement for limiting the surface temperature of the
appliance.
NOTE 2 All operations which the user carries out, including loading and emptying of the appliance, adjusting
controls and de-ashing should be easy, safe and effective.
4.2.1.2 Durability
The durability aspects of the appliance shall be deemed to be satisfied if it is shown to meet
the constructional requirements specified in 4.2.2 to 4.2.13, the safety requirements specified
in Clause 5 and the performance requirements specified in Clause 6.
NOTE The long practice with these products shows that such an approach for dealing with durability is
sufficient.
