Suction pipe length (m)
Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80 (fig. 24)
Thanks to the boiler characteristics, a flue gas discharge pipe ø 80 can
be connected to the ducting ranges Ø50 - Ø60 - Ø80.
For the ducting, you are advised to make a project calculation in
order to respect the relevant standards in force.
The table shows the standard configurations allowed.

(*) Use flue gas system accessories in plastic (PP) for condensing boilers:
Ø50 and Ø80 H1 class and Ø60 P1 class.
The boilers are factory set to:
25 R.S.I.: 4.900 r.p.m. (CH) and 6.100 r.p.m. (DHW) and the maximum
length that can be reached is 7 m for the ø 50 pipe, 25 m for the ø 60 pipe
and 75 m for the ø 80 pipe.
Should it be necessary to achieve greater lengths, compensate the pres-
sure drop with an increase in the r.p.m.of the fan, as shown in the adjust-
ments table, to ensure the rated heat input.
The minimum calibration is not modified.

4 - SWITCHING ON AND OPERATION
4.1 Switching on the appliance
When the boiler is first started the siphon for collecting the
110
100 105
condensate is empty.
It is therefore indispensable to create a head of water filling the
siphon before starting up, following these instructions:
- remove the siphon by releasing it from the plastic pipe connec-
ting to the combustion chamber
- fill the siphon about 3/4" full with water, making sure it is free of
any impurities
- check the float of the plastic cylinder
- put back the siphon, being careful not to empty it, and secure it
with the clip
The plastic cylinder inside the siphon has the job of preventing combustible
gas coming out into the surroundings if the appliance is started without first
creating the head of water in the siphon.
Repeat this operation during routine and extraordinary maintenance opera-
tions.
Every time the appliance is powered up, a series of data is shown on the
display including the flue gas sensor meter reading (-C- XX) (see paragraph
4.3 - fault A09); the automatic purge cycle then starts, lasting around 2 min-
utes. During this phase, the symbol
To interrupt the automatic purge cycle proceed as follows:
access the electronic board by removing the housing, turning the instru-
ment panel towards you and opening the board casing (fig. 16)
Then:
- using a small screwdriver included, press the CO button (fig. 26).
Live electrical parts (230 V AC).
To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the flow of fuel
- set the room thermostat to the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fig. 27) within the area marked
+ and -, the boiler provides hot water for heating and, if connected to an
external storage tank, supplies hot water for DHW.
If there is a heat request, the boiler switches on. The digital monitor indi-
cates the heating water temperature, the icon to indicate heating and the
flame icon (fig. 29).
If there is a domestic hot water request, the boiler switches on.
The digital display shows the hot water system temperature, the icon to
indicate the hot water supply and the flame icon (fig. 30)
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 27) within the area marked + and -.
Depending on the type of system, it is possible to pre-select the suitable
temperature range:
- standard systems 40-80°C
- floor systems 20-45°C.
For further details, consult the "Boiler configuration" section.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery tempera-
ture is automatically chosen by the system which rapidly adjusts ambient
temperature to the changes in external temperature. To increase or decre-
ase the temperature with respect to the value automatically calculated by the
electronic board, turn the heating water selector clockwise to increase and
anticlockwise to decrease. Adjustment settings range from comfort levels - 5
to + 5 which are indicated on the digital display when the knob is turned.
Summer mode (only active when the external storage tank is connect-
ed): turning the selector to the summer mode symbol
the traditional domestic hot water only function, the boiler supplies water
at the temperature set on the external storage tank.
If there is a domestic hot water request, the boiler switches on. The digital
display shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon (fig. 30).
