When necessary, the flue gas flange ( A ), must be removed or replaced
using a screwdriver as a lever.
In this case, the combustion supporting air is taken from the
room in which the boiler is installed, which must be a suitable
and ventilated technical room.
Non-insulated fumes outlet ducts are potential sources of danger.
It is appropriate to install a condensate collector and specific
pipes. In this case realize an inclination of 3° to the condensate
collector.

“SEALED” INSTALLATION (TYPE C)
The boiler must be connected to concentric or twin fumes discharge
and air intake ducts which must both be taken outside. Do not use
the boiler without them.
Concentric outlets (ø 60-100, fig. 10d)
The concentric outlets can be placed in the most suitable direction
according to room requirements.
For installation, follow the instructions supplied with the kit.
When necessary, the flue gas flange ( A ), must be removed or replaced
using a screwdriver as a lever.

Concentric outlets (ø 80-125, fig. 10g)
The boiler has been designed to be connected to concentric outlet/
suction pipes and with the opening for air suction closed.
The concentric outlets can be placed in the most suitable direction
according to room requirements, complying with the maximum lengths
indicated in the table.
For installation, follow the instructions supplied with the kit.
To go through the wall, drill a hole of Ø 130 mm.
According to the length of the pipes used, it is necessary to insert a
flange selecting from those contained in the boiler.
Pay special attention to external temperature and pipe length. Refer
to the diagram (fig. 10h) in order to establish if it is compulsory or not
to use a condensation collector. In case of operation at temperature
lower than 60 °C, it is compulsory to use a condensation collector. If
a condensation collector is used, provide a slope of the flue exhaust
pipe of 3° towards the collector.
Connect the condensation trap syphon to a white water outlet pipe.
Non insulated outlet pipes are potential sources of danger.

If it is necessary to install the boiler on systems already existing (replacement
types Residence KIS), there is a “reduced concentric bend kit” available that
allows positioning the boiler by keeping the same flue gas hole.

Twin outlets (ø 80, fig. 10e)
Twin outlets can be placed in the most suitable direction according to
the room requirements.
Remove the closure plug secured with the screws and use the specific
adaptor for the combustion air intake pipe ( E ).
The air inlet adaptor ø 80 ( E ) must be correctly directed, it is
necessary to fasten it with the appropriate screws, so that the
positioning flap does not interfere with the shell.
When necessary, the flue gas flange ( A ), must be removed using
a screwdriver as a lever. The table indicates the permitted linear
lengths. According to the length of the pipes used, it is necessary to
insert a flange, selecting one from those contained in the boiler (see
the following table).
