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;
