Dieses Dokument legt die Konstruktionsmerkmale, Funktionen und Markierungen in Zusammenhang mit der Sicherheit und der wirtschaftlichen Verwendung von Energie von tragbaren, flachen Gasgeräten fest, die direkt mit LPG-Dampfdruck versorgt werden und über eine integrierte Gaskartusche in Übereinstimmung mit EN 417:2012 verfügen, die horizontal in das Gehäuse eingebaut ist.
ANMERKUNG 1 Diese Geräte werden im gesamten Text als „Geräte“ bezeichnet.
Dieses Dokument ist nur für Geräte anzuwenden, die für die Verwendung im Freien oder in gut belüfteten Bereichen bestimmt sind.
Dieses Dokument ist nicht für Geräte anzuwenden, die von einer externen Gasquelle versorgt werden.
Abgedeckt sind beispielsweise folgende Arten von Geräten:
a) Kochgeräte (Kocher, Grills);
b) Heizgeräte.
Dieses Dokument legt die Anforderungen an diese Geräte bzw. deren funktionswichtige Bauteile fest, unabhängig davon, ob letztere separat oder in eine Baugruppe integriert sind.
Durch dieses Dokument sind nur Geräte abgedeckt, die nicht an Abgasleitungen zur Abführung der Verbrennungsprodukte und nicht an das elektrische Netz angeschlossen sind.
Dieses Dokument bezieht sich weder auf Geräte, die mit Flüssiggas (LPG, en: liquefied petroleum gas) in flüssiger Phase versorgt werden, noch auf Geräte mit fest eingebautem, durch den Anwender nachfüllbarem oder nicht nachfüllbarem Gasbehälter.
Dieses Dokument bezieht sich nicht auf Geräte der Kategorie mit unmittelbarem Propandruck.
Die Anforderungen an die wirtschaftliche Nutzung der Energie wurden in Hinblick auf die Brenner der Kocher berücksichtigt.
ANMERKUNG 2 Dagegen wurden derartige Anforderungen nicht für die anderen Gerätearten festgelegt, denn:
- für Grills ist das Kochergebnis je nach Art der Nahrung und der Region, in der das Gerät eingesetzt wird, unterschiedlich;
- für Heizgeräte wird die gesamte Wärme auf die Umgebung übertragen.

or by endorsement, at the latest by November 2021, and conflicting national standards shall be withdrawn at the

latest by November 2021.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document has been prepared under a mandate given to CEN by the European Commission and the European

Free Trade Association, and supports essential requirements of EU Regulation (EU) 2016/426 of the European

Parliament and of the Council of 9 March 2016 on appliances burning gaseous fuels and repealing Directive

2009/142/EC.

For relationship with EU Regulation (EU) 2016/426, see informative Annex ZA, which is an integral part of this

document.

Appliances covered by this document differ from the ones covered by EN 521:2019+AC:2019 by the fact that the

1 Scope

This document specifies the construction characteristics, performances and marking related to safety and the

rational use of energy of portable, flat gas appliances directly supplied at the LPG vapour pressure, incorporating

a gas cartridge complying with EN 417:2012, inserted horizontally in the chassis.

NOTE 1 These appliances are referred to in the body of the text as “appliances”.

This document covers appliances for outdoor or in well ventilated areas uses only.

This document does not cover appliances supplied by an external gas source.
For example, the following types of appliances are covered:
a) cooking appliances (stoves, barbecues);
b) heating appliances.

This document specifies the requirements applicable to these appliances or their functional sections whether or

not the latter are independent or incorporated into an assembly.

Appliances covered by this document are not connected to a flue for the discharge of products of combustion and

are not connected to the mains electricity supply.

This document covers neither appliances supplied with LPG in the liquid phase nor appliance with fixed integral

container which could be refilled by the user.
This document does not cover appliances of direct pressure propane category.
Requirements for rational use of energy have been considered for stove burners.

NOTE 2 However, such requirements have not been considered for the other types of appliances because:

— for barbecues, this type of cooking varies according to the type of food and region where the appliance is used;

— for heating appliances, all the heat produced is discharged into the environment.

European foreword

This document (prEN 17476:2020) has been prepared by Technical Committee CEN/TC 181 “Dedicated

liquefied petroleum gas appliances”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.

This document has been prepared under a mandate given to CEN by the European Commission and the European

Free Trade Association, and supports essential requirements of EU REGULATION (EU) 2016/426 OF THE

EUROPEAN PARLIAMENT AND OF THE COUNCIL of 9 March 2016 on appliances burning gaseous fuels and

repealing Directive 2009/142/EC.

For relationship with EU REGULATION (EU) 2016/426), see informative Annex ZA, which is an integral part of

this document.

Appliances covered by this document differ from the ones covered by EN 521:2019 by the fact that the gas

cartridge is incorporated inside the appliance body in a position which can create particular situations which

need different approach than these used in EN 521:2019.

1 Scope

This document specifies the construction characteristics, performances and marking related to safety and the

rational use of energy of portable, flat gas appliances directly supplied at the LPG vapour pressure, incorporating

a gas cartridge complying with EN 417:2012, inserted horizontally in the chassis.

NOTE These appliances are referred to in the body of the text as “appliances”.

This document covers appliances for outdoor or in well ventilated areas uses only.

For example the following types of appliances are covered:
a) cooking appliances (stoves, grills, barbecues);
b) heating appliances;

The requirements apply to these appliances or their functional sections whether or not the latter are independent

or incorporated into an assembly.

Appliances covered by this document are not connected to a flue for the discharge of products of combustion and

are not connected to the mains electricity supply.

This document covers neither appliances supplied with LPG in the liquid phase nor appliance with fixed integral

container which may or may not be refilled by the user.
This document does not cover appliances of direct pressure propane category.
Requirements for rational use of energy have been considered for stove burners.

NOTE However, such requirements have not been considered for the other types of appliances because:

— for grills, this type of cooking varies according to the type of food and region where the appliance is used;

— for heating appliances, all the heat produced is discharged into the environment;
