Intake and outlet systems.
(see the intake and outlet terminal instructions).
The EOLO Mini kW Special boiler is designed for connecting
the couple-on air intake/outlet pipes and can be installed indo-
ors or outdoors (in a partly sheltered location) in the following
configurations:
Outdoors (in a partly sheltered location):
- room-sealed fan-assisted with direct intake (type C) using
the (optional) compulsory top cover kit;
- room-sealed fan-assisted (type C) using the vertical or hori-
zontal concentric kits, keeping the side plates and without
having to use the top cover kit.
Indoors:
- fan-assisted with open chamber (type B
22
) using the (optional)
compulsory top cover kit;
- room-sealed fan-assisted (type C) using the vertical or hori-
zontal concentric kits or the 80/80 Ø separator kit.
As far as concerns the pressure losses of each accessory, the
various combinations that can be created and the use of the
diaphragms to install depending on the length of the pipes
see
the instructions for the air intake/outlet terminals (boiler
instruction manual)
.
The coupling of the accessories (curves, extensions, terminals)
is the push-fitting type and sealing is ensured by silicon lip
seals.
Room-sealed fan-assisted configuration with
direct air intake (type C) for outdoor installa-
tion in a partly sheltered location (see figure on
the right)
.
By using the cover (1), on top of the sealed chamber, the boiler
can be installed outdoors in a partly sheltered place.
Note:
in the 28 kW Special version, besides the cover (1), the
counterframe covering sheet (4) must also be mounted, fixing
it to the frame with two screws.
Intake.
In order to mount the cover (1) the two plates (3) – closing the
holes at the top of the sealed chamber – have to be removed.
Combustion air is taken directly from the environment,
exploiting the gap between the bottom of the cover (1) and
the top of the boiler.
Note:
in the 28 kW Special version it is compulsory to cover
the left intake hole with the plate (3).
Exhaust.
A flange (2) is used for coupling the 80 mm diameter outlet pi-
pes, used in the split systems. You can have either a horizontal
(A) or vertical (B) outlet depending on the accessories used.
To avoid condensate problems, the outlet pipe should be li-
mited
to 5 straight metres for normal pipes and 12 straight
metres for insulated pipes.
Maximum permitted length is 12 straight metres.
Note:
To ensure the boiler works properly with this kit it is
necessary to install a 40 Ø (EOLO 24 kW Special) or a 42.5 Ø
(EOLO 28 kW Special) diaphragm at the outlet of the sealed
chamber and before the outlet pipe
(see the boiler instruction
manual)
.
Fan-assisted with open chamber (type B
22
) for
indoor installation (see figure above).
The cover kit described previously is used. By removing the
side plates from the sealed chamber, air is taken in directly
from the room where the boiler is installed.
Fumes are discharged through 80 diameter pipes in a single
flue or directly outside.
