The EOLO Star 23 kW is designed for being connected to the
special intake/exhaust coupling pipes.
(until serial number 2972938) It is possible to use the concen-
tric flue pipes (Ø60/100 and Ø80/125), only.
(from serial number 2972939) over than the concentric flue
pipes (Ø60/100 and Ø80/125) it is also possible to use the
Ø80/80 coupling type separator kits.
These kits are able to split the air inlet and discharge of the
exhaust flues.
Sealed chamber, fan-assisted configuration
(type C).
Exhaust.
Connection to the fumes exhaust pipes is through a flange (1)
or a flanged curve to fix to the fitting (4) at the top of the sealed
chamber, placing a shaped seal in between (6).
The flange differs according to whether the system is used split
or concentric.
In the first case, the passage for the intake of combustion air
(5) is closed while in the second case it is used.
To ensure correct operation of the boiler it is necessary to put
a diaphragm (7) on the exhaust fitting (4), between it and the
flange used (1).
There are different diameter diaphragms, mounted accord-
ing to the type of pipe and its length
(see boiler instruction
booklet).
Intake.
Using the split system, connection to the intake pipes is done
in exactly the same way as for the exhaust pipes, connecting
to one of the two 80 mm Ø holes (2) at the top of the sealed
chamber.
The unused hole is closed with one of the plastic caps (3) sup-
plied with the boiler.
If coaxial pipes are used, the intake of combustion air is done
exploiting the concentric hole, outside the exhaust fitting
(5).
Intake and Exhaust Kits.
The kits and their accessories permit use of four concentric
systems and two split systems.
As regards pressure losses relating to each accessory, the various
possible combinations and the use of the diaphragms depend-
ing on the length of the pipes used, follow the instructions
given for the intake and exhaust terminals (see the boiler
instruction booklet) .
The coupling of the accessories (bends, extensions and termi-
nals) is the fitted type while sealing is guaranteed by silicone
lip seals.
Coupling type horizontal concentric kit Ø 60/100.
The exhaust pipe (60 mm Ø) is fitted inside the aspiration
pipe (100 mm Ø).
Connection to the boiler is done using a 90° bend (2) that can
be positioned in any direction and which, by means of the
necessary extensions, is connected to the specific aspiration
and exhaust terminal (3).
The maximum overall permitted length beyond the first bend
(2) is 3 straight horizontal metres.
Extraction and exhaust systems.
Coupling type horizontal concentric kit Ø 80/125.
The exhaust pipe (80 mm Ø) is fitted inside the aspiration
pipe (125 mm Ø).
Connection to the boiler is done using a 90° 60/100 Ø bend
(2) that can be positioned in any direction and which, by
means of the 60/100-80/125 adapter (3) and necessary ex-
tensions, is connected to the specific aspiration and exhaust
terminal (4).
The maximum overall permitted length beyond the first bend
(2) is 7.3 straight horizontal metres.
