RESIDENCE KIS
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 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 ( 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 conden -
sation 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.

If it is necessary to install
Residence KIS on systems
alreadyexisting (replacement
types Residence KIS), there is
a “reduced concentric bendkit”
available that allows positio-
ning the boiler by keeping the
same flue gas hole.

POSSIBLE OUTLET CONFIGURATIONS (fig. 25)
B22P-B52P Intake inside and outlet outside
C12 Concentric wall outlet. Pipes can leave the boiler independently, but the outputs must be concentric
or near enough in order to be subjected to similar wind conditions (within 50 cm).
C22 Concentric outlet in regular smoke pipe (suction and outlet in the same pipe).
C32 Concentric roof outlet. Output as C12.
C42 Outlet and suction line in regular separate smoke pipes, but subjected to similar wind conditions.
C52 Separate wall or roof outlet and suction line and in areas with different pressures. Outlet and
suction line must never be placed on opposite walls.
C62 Outlet and suction line carried out with pipes marketed and certified separately (1856/1).
C82 Outlet in single or regular smoke pipe and wall suction line.
C92 Roof outlet (like C33) and air intake from a single existing smoke pipe.
TWIN O UTLETS (ø 80)
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 (E-F fig. 23)
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 (E) must be correctly oriented, it is the -
refore necessary to fix it using the appropriate screws, so that the
locating tab does not interfere with the casing.
When necessary, the flue gas flange (L) must be removed using a screwdri -
ver 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).
