The first start-up must be carried out by personnel from the relevant
Technical Assistance Centre. Before starting up the boiler, check:
that the data of the supply networks (electricity, water, gas) corre-
spond to the label data
that the flue gas evacuation and air intake pipes comply with current
regulations and respect the maximum permissible lengths
that conditions for regular maintenance are guaranteed if the boiler is
placed inside or between items of furniture
the seal of the fuel adduction system
that the fuel flow rate corresponds to values required by the boiler
that the fuel supply system is sized to provide the correct flow rate to
the boiler, and that it has all the safety and control devices required
by current regulations
that the circulator rotates freely because, especially after long periods
of inactivity, deposits and/or debris can prevent free rotation

5.2
Initial start-up
On first start-up, in the event of prolonged non-use and in the event of
maintenance work, it is essential to proceed as described in the following
paragraphs before putting the appliance into operation.
At the first start-up, the calibration procedure (GAC) is also recommen-
ded to allow the boiler to reach its optimal performance.
5.2.1
Condensate trap filling
Fill the condensate collection drain-trap, pouring about 1 litre of water
into the boiler combustion analysis outlet, and check that:
- the water leaving the boiler via the discharge tube is running off cor-
rectly
- the seal on the condensate discharge connection line.

level (max).

on action or after 60 days of non-use (electrically powered boiler). In this
mode the boiler, for 60 minutes, limits the power in heating to a minimum
and the maximum temperature in DHW to 55°C. Activating the combus-
tion analysis temporarily disables this function.
During execution, the function is shown on the display with the mes-
MODE".
5.3
Venting cycle
Turn the main system switch ON.
Every time the boiler is energised, a 4-minute vent cycle is performed.
The display shows:
To interrupt the vent cycle press

When the vent cycle is running all heat requests are inhibited
except for DHW requests when the boiler is not in OFF.
The cycle can also be interrupted by a DHW request, if the boiler is not
OFF.

Manual calibration procedure (GAC)
The GAC procedure, which is useful to calibrate the gas valve and
combustion control system, is mandatory following: gas conversion - gas
valve replacement - board replacement - fan replacement - cleaning of
electrode (ionisation) - replacement of burner insulation panel -

however it may be limited in performance and may also process com-
bustion control signals.

Any repetition of the GAC that is not successfully completed leaves the
system in the "GAC not completed"
