Concentric pipes (ø 80/125)
The boiler has been designed to be connected to concentric outlet/
suction pipes and with the opening for air suction closed. The concen-
tric 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 140 mm. According to the length
of the pipes used, it is necessary to insert a flange selecting from
those contained in the boiler (see table). Pay special attention to
external temperature and pipe length. Refer to the diagrams 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 1% towards the collector.
Connect the condensation trap syphon to a white water outlet pipe.
Non insulated outlet pipes are potential sources of danger.

TWIN OUTLETS (ø 80) (fig. 11)
Twin outlets can be placed in the most suitable direction according
to the room requirements.
To use the combustion air suction pipe, one of the two inlets (G and
H) must be selected. Remove the closure plug which is fixed using
screws, and use the specific adaptor relating to the inlet selected.
The air inlet adaptor ø 80 (X) must be correctly oriented, it is
therefore necessary to fix it using the appropriate screws, so
that the locating tab does not interfere with the casing: X air
inlet adaptor ø 80 - Y air inlet adaptor from ø 60 to ø 80.
When necessary, the flue gas flange (F) 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).
The maximum lengths of individual pipes are shown in the graphs
(fig. 11).

reduced concentric bend kit
If it is necessary to install Quadra on existing systems (replace-
ment of Ciao N/Ciao range), there is a "reduced concentric bend"
kit that allows boiler positioning while keeping the same flue
gas hole.
