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
circulation pump will start to run.
•
Use
button
5
to set the SUMMER, WINTER or
SUMMER/WINTER function. L.e.d.s
8
and/or
9
will light up to indicate that the boiler is working.
•
The automatic ignition system will then light the
burner. It may however be necessary to repeat
the operation a number of times 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
(fig. 1 page 10)
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 external filling
loop until the indicator
11,
lights up and the
pressure on the pressure gauge reads 1 bar,
and then close the filling loop and remove
the flexible hose connection
.
•
Unscrew the aluminium plug and insert an
analyser in the exhaust sampling point
PF
(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
(fig. 1) on the
venturi clockwise to reduce the CO2 value or
anticlockwise to increase it.
