4.3 Starting up the boiler
Once the system has been filled, proceed as
follows:
•
Check that the exhaust flue is free of
obstructions and correctly connected to
the boiler;
•
Switch on the power supply to the boiler;
•
Open the gas isolation valve;
•
Place switch 1 in the ON position (see
2.7 “Control Panel”), after a few seconds
the circulating pump will start to run;
•
Use button 6 to set the SUMMER,
WINTER or SUMMER/WINTER function. The
symbols
will light up (fixed light) to
indicate that the boiler is working;
•
The automatic ignition system will then light
the burner. This operation is repeated for 3
times. It may however be necessary to repeat
the operation in order to eliminate all the air
from the pipes. To repeat the operation, wait
approximately three minutes before re-
attempting to light the boiler. To reset the
boiler Switch off switch 1 (see 2.7 “Control
Panel”) and switch it back on again and repeat
the lighting procedure;
•
With the boiler ignited, if the system still emits
noises, the operations must be repeated until
all the air has been removed;
•
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, adjust screw V (see fig. 1) on
the venturi clockwise to reduce the CO2 value
or anticlockwise to increase it
;
