EOLO MAIOR @
EXTRACTION AND EXHAUST SYSTEMS
(see extraction and exhaust end instructions )
The EOLO Maior @ series of boiler are ready for connection to the special coupling type extraction and
exhaust pipes.
- EXHAUST
Connection to the exhaust pipes is done by means of a flange
(1) or a flanged curve to be fastened to the union (4) on the top
part of the sealed chamber after placing in between a special
shaped seal (6).
The flange differs according to whether the doubled or
concentric system is used. In the former case, the opening for
extraction of combustion air (5) is closed, while in the latter
case, this is used.
For correct boiler operation, a diaphragm (7) must be fitted on
the exhaust (4) in between the flange used (1).
Diaphragms of different diameter are available which must be
fitted according to the type of pipe and its length
(see boiler
instruction booklet).
- EXTRACTION
Using the doubled system, connection to the extraction
pipes is done in the same way as the exhaust pipes, by
connecting up to one of the two 80 mm diameter holes (2)
on the top part of the sealed chamber. The hole which is not
used is closed by means of one of the special caps (3)
equipping the boilers.
If coaxial pipes are used, extraction is done through the concentric hole outside the exhaust pipe (5).
- EXTRACTION EXHAUST KIT
The kits and relevant accessories make it possible to use four concentric systems and two doubled systems.
As regards pressure drop relating to each accessory, the various possible combinations and the use of the
diaphragms to be fitted according to the length of the pipes,
see the instructions concerning the extraction
and exhaust ends (boiler instruction booklet).
The accessories (
curves, extensions and end pieces
) are of the
coupling type and seal is provided by special lip seals.
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.
