4.5 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;
•
Check the pressure in the system. If the
pressure has fallen, re-open the filling tap until
the code H2O
disappears on the display
and
the pressure gauge reads 1 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, adjust screw
V
(see fig. 1) on the venturi clockwise to reduce the CO2 value or anticlockwise to
increase it
