Independent gas-fired flueless space heaters for nominal heat input not exceeding 6 kW

This document specifies, for the purpose of type examination, the requirements and test methods for construction, safety, marking and rational use of energy of 2nd and 3rd family gas-fired domestic flueless space heating appliances having a nominal input not exceeding 6 kW (based on net calorific value).
It covers the following Type AAS fixed flueless heaters:
   Note: These are type A appliances fitted with an atmosphere sensing device, with or without a       fan
a)   heaters with or without a catalytic converter;
b)   Category 1 appliances burning gases of the second family;
c)   Category 2 appliances burning gases of the second and third families.
It does not cover
a)   Mobile heaters.
b)   Category 1 appliances burning gases of the third family.
c)   Portable flueless heaters.
d)   Diffusive catalytic combustion heaters.
There are no specific thermal efficiency requirements appropriate to these types of appliance as:
a)   All the heat produced by the combustion process is released into the space to be heated.
b)   The requirements with regard to the combustion performance, which is a safety matter, ensure the effective burning of the fuel gas.
This standard is only applicable to appliances which are to be type tested. Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary devices are not dealt with by this standard.

Konvektions-Raumheizer ohne Abgasabführung für gasförmige Brennstoffe mit einer Nennwärmebelastung kleiner oder gleich 6 kW

Diese Europäische Norm legt Anforderungen und Prüfbestimmungen für Bau, Sicherheit, Kennzeichnung und rationelle Energienutzung von Konvektions-Raumheizern ohne Abgasabführung für gasförmige Brennstoffe mit einer Nennwärmebelastung kleiner oder gleich 6 kW (bezogen auf den unteren Heizwert) fest, die für Gase der 2. und 3. Familie gebaut sind. Diese Norm gilt für Baumusterprüfungen.
Sie gilt für folgende Gerätetypen:
a) Fest eingebaute Heizer ohne Abgasabführung;
b) Heizer ohne Abgasführung mit Katalysator;
c) Geräte der Kategorie 1, die Gase der 2. Familie verbrennen;
d) Geräte der Kategorie 2, die Gase der 2. und 3. Familie verbrennen.
Sie gilt nicht für
a) Mobile Heizgeräte mit einer Nische für die Installation von Flüssiggasbehältern, transportable wiederauffüllbare Flüssiggasbehälter oder Geräte für flüssige Brennstoffe.
b) Geräte der Kategorie 1, die Gase der 3. Familie verbrennen
c) tragbare Heizer ohne Abgasabführung.
Es gibt keine spezifischen Bestimmungen des thermischen Wirkungsgrades, die für diese Gerätetypen geeignet sind wie:
a) Die gesamte Hitze, die durch den Verbrennungsprozess entsteht, gelangt an die Stelle, die beheizt werden soll.
b) Die Bestimmungen bezüglich der Verbrennungsleistung, die eine Sicherheitsangelegenheit darstellt, stellen die wirkungsvolle Verbrennung der Abgase sicher.
Diese Norm ist lediglich anwendbar auf Geräte, die geprüft werden sollen.

Appareils de chauffage domestiques non raccordés indépendants utilisant les combustibles gazeux pour un débit calorifique nominal inférieur ou égal a 6 kW

Le présent document spécifie, pour les besoins d'un examen de type, les exigences et les méthodes d'essai relatives a la construction, la sécurité, le marquage et l'utilisation rationnelle de l'énergie par les appareils de chauffage domestiques non raccordés utilisant les combustibles gazeux des deuxieme et troisieme familles, dont le débit nominal est inférieur ou égal a 6 kW (sur la base du pouvoir calorifique inférieur).
La présente norme couvre les types d'appareil suivants :
a) les appareils de chauffage fixes non raccordés ;
b) les appareils de chauffage non raccordés comportant un convertisseur catalytique ;
c) les appareils de catégorie 1 utilisant des gaz de la deuxieme famille ;
d) les appareils de catégorie 2 utilisant des gaz des deuxieme et troisieme familles.
La présente norme ne couvre pas :
a) les appareils de chauffage mobiles intégrant un compartiment d'installation pour une bouteille portative rechargeable et transportable de GPL ou autres appareils a gaz de pétrole liquéfié exclusivement ;
b) les appareils de catégorie 1 utilisant des gaz de la troisieme famille ;
c) les appareils de chauffage non raccordés portatifs.
Il n'existe aucune exigence spécifique concernant le rendement thermique, appropriée a ces types d'appareils, dans la mesure ou :
a) toute la chaleur produite par le processus de combustion se dégage dans l'espace a chauffer ;
b) les exigences concernant les performances de combustion, qui relevent de la sécurité, assurent la combustion effective du combustible gazeux.
La présente norme s'applique uniquement aux appareils devant etre soumis a un essai de type.
