6.5.1 Classification
B
23
An appliance intended to be connected to a flue that evacuates
the products of combustion to the outside of the room containing
the appliance. The combustion air is drawn directly from the room.
B
23P
A type B appliance intended to be connected to a flue system that
23
is designed to operate at a positive pressure
B
33
Appliance designed for connection to a common duct system
incorporating a fan upstream of the combustion chamber/heat
exchanger. This common duct system consists of a single natural
draught flue. Combustion air is drawn into the appliance from the
room by means of a concentric duct, which encloses the flue. The
combustion air is drawn directly from the room and enters through
defined orifices situated in the surface of the duct.
C
13
Appliance that is designed for connection via its ducts to its
horizontal terminal, which at the same time admits fresh air to the
burner and discharges the products of combustion to the outside
through orifices that are either concentric or close enough to come
under similar wind conditions.
must be fitted inside a 50 cm square. Detailed instructions are
provided with the individual accessories.
C
33
Appliance that is designed for connection via its ducts to a vertical
terminal, which at the same time admits fresh air to the burner
and discharges the products of combustion to the outside through
orifices that are either concentric or close enough to come under
similar wind conditions. The terminals for separate flues must be
fitted inside a 50 cm square. Detailed instructions are provided
with the individual accessories.

C
43
Appliance connected via its two ducts to a common duct system designed
for more than one appliance. This common duct system consists of two
ducts connected to a terminal, which at the same time admits fresh air
to the burner and discharges the products of combustion to the outside
through orifices that are either concentric or close enough to come under
similar wind conditions.
C
53
Appliance connected via its separate ducts to separate terminals for
the supply of combustion air and the evacuation of the products of
combustion. These ducts may terminate in zones of different
but not on different walls of the building.
C
63
Appliance which is intended to be connected to a separately approved
and marketed system for the supply of combustion air and discharge
of the combustion products. The pressure drop of the ducts must not
exceed 100 Pa. The ducts must be certified for this specific use and for
a temperature in excess of 100°C. The flue terminal must be certified to
EN 1856-1.
C
83
Appliance connected via one of its ducts to a single or common duct
system. This duct system consists of a single natural draught duct (i.e.
not incorporating a fan) that evacuates the products of combustion. The
appliance is connected via a second of its ducts to a terminal, which
supplies air to the appliance from outside the building.
C
93
Appliance similar to a type C
33
with a vertical terminal, which at the same time admits fresh air to
the burner and discharges the products of combustion to the outside
through orifices that are either concentric or close enough to come
under similar wind conditions.
