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 2 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
reaches the middle of the green area (1,2 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
;
