4 Classification of appliances
4.1 Classification according to the nature of the gases used (categories)
4.1.1 Classification of gases
Gases are classified into three families, possibly divided into groups as a function of the Wobbe index in
accordance with the values given in EN 437:2021, Table 1.
4.1.2 Appliance categories
Appliance are classified into categories defined according to the gases and the pressures for which they
are designed as given in EN 437:2021, 6.1.

4.2 Classification according to the method of evacuation of the products of combustion
Appliances are classified into types according to the method of evacuation of the products of
combustion and of admission of the combustion air:
• Type B: An appliance intended to be connected to a flue which evacuates the products of
combustion to the outside of the room containing the appliance. The combustion air is drawn
directly from the room.
• Type B : A type B appliance incorporating a draught diverter.
