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.

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

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

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

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

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;
