integral part of the boiler and are provided by
Sime
as an accessory kit, to be ordered separately from the appliance on the basis of the
type permitted and the system requirements.

Combustion air inlet into the atmosphere and smoke outlet to
open air.
Combustion air inlet into the atmosphere and smoke outlet into
single flue.
NOTE:
opening for combustion air (6 cm
2
x kW).
C(10)3
Type C appliance connected, via conduits, to a collective pipe
designed for more than one appliance. The collective pipe is
made up of two conduits connected to a terminal which also
feeds in air from outside the burner and evacuates the combus-
tion products externally through concentric orifices or those
close enough to result in the same wind conditions.
NOTE:
the boiler can be type C(10)3 only with accessory code
6296543.
If this accessory is used, it is necessary to increase by
15%
the
value of the
Minimum power heating/domestic hot water (pre-
mix)
; set the value of
PAR 20 = 15
. Install this accessory only
when separate flues are installed on the boiler;
DO NOT use it
when concentric flue are installed
.
C13
Concentric wall smoke outlet The pipes can start from the
boiler but the outlets must be concentric or close together (no
more than 50 cm) to be subject to similar wind conditions.
C33
Concentric roof smoke outlet The pipes can start from the
boiler but the outlets must be concentric or close together (no
more than 50 cm) to be subject to similar wind conditions.
C43
Outlet and inlet in shared or separate flue pipes but subjected
to similar wind conditions.
C53
Separate wall or roof inlet and outlet in different pressure ar-
eas.
NOTE:
the inlet and outlet must never be positioned on oppos-
ing walls.
C63

WARNINGS
– The smoke flue and the connection to the flue pipe must be in compliance with the national and local standards and legisla-
tion in force in the country where the appliance will be used.
– The use of rigid ducts which are resistant to temperature, condensate, mechanical stress and are air-tight is compulsory.
– Outlet ducts which are not isolated are a risk of danger.
