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.
• For the purposes of this standard a type B appliance is an a

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee

CEN/TC 62.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations

which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other

language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC

Management Centre has the same status as the official versions.
