EXTRACTION AND EXHAUST SYSTEMS
(see extraction and exhaust end instructions )
EOLO Mini is set for connecting to the special extraction/exhaust coupling ducts.
- EXHAUST
Connection to the exhaust ducts is done by means of a
flange (1) or a curved flange to be fitted to the
connector (4) on the top part of the sealed chamber,
placing in between a special shaped seal (6).
The flange differs according to whether the doubled or
concentric system is used.
In the first case, the opening for combustion air
extraction (5) is closed while in the second case, it is
exploited.
For correct boiler operation, a diaphragm (7) must be
placed on the exhaust connector (4) in between the
flange used (1).
Diaphragms of different diameter are contemplated
which must be fitted according to the type of duct and
its length (see boiler instruction booklet).
- EXTRACTION
Using the doubled system, connection to the extraction ducts is done in the same way as the exhaust pipes,
connecting up to one of the two 80 mm dia. holes (2) on the top part of the sealed chamber.
The unused hole is closed by means of one of the special caps (3) featured on the boilers.
In the event of coaxial pipes being used, extraction takes place by exploiting the concentric hole outside the
exhaust connector (5).
Coupling type horizontal concentric kit 60 /100
The exhaust pipe (φ 60 mm) is fitted inside the extraction
pipe (φ 100 mm).
Connection to the boiler is made using a 90° curve (1)
that can be positioned in any direction and which, by
means of the necessary extensions, must be connected to
the special extraction and exhaust end (2).
Max possible overall length beyond the first curve (1) is
3 straight and horizontal metres.
Coupling type horizontal concentric kit 80 /125
The exhaust pipe (φ 80 mm) is fitted inside the extraction
pipe (φ 125 mm).
Connection to the boiler is made using a 90° curve
diameter 60/100 (1) that can be positioned in any
direction and which, by means of the adapter 60/100-
80/125 (2) and necessary extensions, must be connected
to the special extraction and exhaust end (3).
Max possible overall length beyond the first curve (1) is
7.3 straight and horizontal metres.
