4.6 Starting up the boiler
Once the system has been filled, proceed as
follows:
Check that the exhaust duct is free from
obstructions and correctly connected to the flue
exhaust system;
Switch on the power supply to the boiler;
only for the first start-up, the ignition system will
automatically start the ’System purging’ function.
The function code F33
will appear on the display.
When the function is active, the pump circulates but
the burner will not start for 5 minutes. The starting of
the boiler is enabled only once the purging cycle has
been completed.
Open the gas feed valve;
Use
button
to select the WINTER mode. The
symbol
will light up (fixed light) to indicate the
selected operation mode.
In case of RS version with remote storage cylinder,
use button
to select WINTER-SUMMER mode.
The symbol
will light up (fixed light) to
indicate the selected operation mode.
The automatic ignition system will then light the
burner.
In case of flame failure, the ignition system repeats
the ignition procedure after the fan-overrun cycle (20
sec). It may be necessary to repeat the operation in
order to remove all the air from the pipes. To repeat
the operation, wait approximately 5 seconds from the
last ignition attempt before resetting the error code
E01
(pressing the reset button
‘
’).
With the boiler ignited, if the system still emits noises,
the operations must be repeated until all the air has
been removed;
Check the pressure in the system. If the pressure has
fallen, re-open the filling tap until the pressure gauge reads 1.2 ÷ 1.5 bar on completion, close the filling tap.
Unscrew the aluminium plug and insert an analyser in the exhaust sampling point
PF
(see fig. 1) to check the
CO2 value. Make sure that the value complies with that reported in table 1;
If the CO2 value does not correspond to the specified value, carry out adjustment as provided in paragraph
“
5.5.1 – Max. power supply regulation - CO
2
value” ;
