measured by the relative pressure points located at the top of
the sealed chamber (9-10).
When it triggers it causes a switch to close (S6) that acts on the
integrated board enabling or preventing burner ignition.

Fan (5).
e extractor operates downstream from the combustion
chamber and is fixed vertically to the top of the draught diverter
(4) from where it extracts the flue and conveys them to the ex-
haust pipes to which the boiler is connected. It simultaneously
guarantees the flow of air inside the sealed chamber.
A venturi pipe is inserted inside the fan outlet terminal pipe
(1); the negative signal of the pressure switch (6) is detected
on the Venturi pipe outlet.
It is controlled by the integrated board and its operation co-
incides essentially with that of the burner.
Air inlet and exhaust systems.
(see air inlet and exhaust terminal instructions).
EOLO Eco kW is connected to the push-fitting air inlet/
exhaust pipes and can be installed either with a fan-assisted
sealed chamber (type C) configuration or, by means of the
relative kit, the fan-assisted open chamber configuration
(type B
22
).
Fan-assisted, open chamber configuration
(type B
22
) for installing outdoors in a partially
protected place.
U
sing a specific kit, the EOLO Eco kW boiler can be installed
outdoors in a partly sheltered place.
In this way, the appliance works in the fan-assisted open
chamber configuration (type B
22
) so the combustion air can
be taken directly from the environment.
Inlet.
Air inlet is possible through holes present on the external
surface of the flange (2).
e flange must be mounted on the central hole in the upper
side of the sealed chamber after inserting the respective gasket
(1) and fixing it through the 4 screws.
On the flange (2) it is necessary to install the cover cap Ø180
(3) through the two self-tapping screws, combining the two
holes present on the cover cap and on the flange.
