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 fl ange 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 fl ue 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.

CONCENTRIC OUTLETS (ø 60-100)
The boiler has been designed to be connected to concentric outlet/suc-
tion pipes and with the opening for air suction (E) closed (fi g. 10b). The
concentric outlets can be places in the most suitable direction according
to room requirements, com plying with the maximum lengths indicated
in the table.
For installation, follow the instructions supplied with the kit.
According to the length of the pipes used, it is necessary to insert a
fl ange, selecting one from those contained in the boiler (see the follow-
ing table). When necessary, the fl ue gas fl ange (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 fl ange, selecting one from those contained in the boiler (see
the following table).
