Decorative fuel-effect gas appliances

This document specifies the requirements and test methods for the construction, safety, and marking of decorative fuel effect gas appliances not exceeding a nominal heat input of 20 kW (based on the net calorific value), thereafter referred to as appliances.
This document is applicable to appliances that are designed to simulate a solid fuel fire and incorporate a natural draught burner with or without an ignition burner. The appliances are for decorative purposes only and are not heating appliances.
This document is applicable to type BAS, as described in 4.2, decorative fuel effect gas appliances that are designed to be installed within a non-combustible builder's opening or a non-combustible fireplace recess.
This document includes additional requirements for Type BBS appliances which are specified in Annex F.
In addition, this document is applicable to decorative fuel-effect gas appliances that are designed to be installed under a non-combustible canopy which is independent or integral with a flue box, for which additional requirements are specified in Annex A.
The use of toxic gases is not covered.
This document is not applicable to:
-   catalytic combustion appliances;
-   appliances in which the supply of combustion air and/or the evacuation of products of combustion is achieved by mechanical means.
NOTE   Requirements concerning the rational use of energy have not been included in this document because the appliances are for decorative purposes.

Dekorative Gasgeräte mit Brennstoffeffekt

Diese Europäische Norm legt die Anforderungen und die neuen Prüfbestimmungen für Konstruktion, Sicherheit, und Kennzeichnung von dekorativen Gasgeräten mit Brennstoffeffekt mit einer Nennwärmebelastung von höchstens 20 kW, (bezogen auf den Heizwert), im Folgenden als Gerät bezeichnet, fest.
Diese Norm gilt für dekorative Geräte mit Brennstoffeffekt, die mit Gas betrieben werden und einen atmosphärischen Brenner mit oder ohne Zündbrenner besitzen. Diese Geräte erfüllen nur eine dekorative Funktion und gelten nicht als Heizgeräte.
Diese Norm gilt für dekorative Gasgeräte mit Brennstoffeffekt der Art BAS - wie in 4.2. beschrieben, die zum Einbau in offene Kamine oder Einbaunischen aus nichtbrennbaren Werkstoffen bestimmt sind.
Dieses Dokument enthält zusätzliche Anforderungen für Geräte vom Typ BBS, die in Anhang F aufgeführt sind.
Außerdem gilt diese Norm für dekorative Gasgeräte mit Brennstoffeffekt, die unter einer nicht-brennbaren Abzugshaube zu installieren sind, welche entweder angebaut oder in einem Abgassystem integriert ist; hierfür sind zusätzliche Anforderungen im Anhang A enthalten.
Diese Norm gilt nicht für:
-   Geräte mit katalytischer Verbrennung;
-   Geräte mit mechanischer Verbrennungsluftzufuhr
und/oder Abgasabführung.
Diese Norm bezieht sich ausschließlich auf Geräte, die für eine Baumusterprüfung bestimmt sind.
Fragen in Zusammenhang mit Qualitätssicherung, Kontrollprüfung während der Produktion und Konformitätszertifikate von Hilfsgeräten werden nicht in dieser Norm behandelt.
In dieser Europäischen Norm sind Anforderungen an die rationelle Energienutzung nicht enthalten, da diese Geräte nur eine dekorative Funktion erfüllen.

Appareils à effet décoratif de combustion utilisant les combustibles gazeux

Le présent document spécifie les exigences et les méthodes d'essais pour la construction, la sécurité et le marquage des appareils à effet décoratif de combustion utilisant les combustibles gazeux de débit calorifique ne dépassant pas 20 kW (par rapport au pouvoir calorifique inférieur), appelés ci-après « appareils ».
Le présent document s'applique aux appareils conçus pour simuler un feu de combustible solide, équipés d'un brûleur atmosphérique avec ou sans brûleur d'allumage. Ces appareils ont un but uniquement décoratif et ne sont pas des appareils de chauffage.
Le présent document s'applique aux appareils de type BAS, comme indiqué en 4.2, les appareils à effet décoratif de combustion utilisant les combustibles gazeux qui sont conçus pour être installés dans la cavité non combustible d'un foyer ou dans le renfoncement non combustible prévu par l'architecte pour le foyer.
Le présent document comprend les exigences complémentaires relatives aux appareils de type BBS spécifiés en Annexe F.
De plus, ce document s'applique aux appareils à effet décoratif de combustion utilisant les combustibles gazeux prévus pour être installés sous une hotte non combustible qui est séparée ou fait partie intégrante de l'appareil avec le conduit d'évacuation des produits de combustion, pour lesquels des exigences complémentaires sont indiquées dans l'Annexe A.
Le présent document ne s'applique pas :
-   aux appareils à combustion catalytique ;
-   aux appareils dans lesquels l'amenée d'air comburant et/ou l'évacuation des produits de combustion est effectuée par un moyen mécanique.
Le présent document ne s'applique qu'aux appareils qui sont destinés aux essais de type.
Les points relatifs à l'assurance qualité des systèmes, aux essais en production et aux certificats de conformité aux équipements auxiliaires ne sont pas traités dans ce document.
Les exigences relatives à l'utilisation rationnelle de l'énergie n'ont pas été traitées dans le présent document, car ces appareils n'ont qu'un but décoratif.
