Annual appliance maintenance.
ES
e following checks and maintenance should be per formed
at least once a year.
- Clean the fl ue side of the heat exchanger.
PL
- Clean the main burner.
- Make a visual inspection of the fl ue extraction hood for
wear or corrosion.
CZ
- Ensure correct ignition and operation.
- Ensure correct settings of the burner.
HR
- Verify correct operation and adjustments of the ap pli ance,
in particular:
- activation of the electrical main switch on the boil er;
SL
- activation of the system control thermostat.
- Ensure sealing effi ciency of the gas intake circuit; insert a
HU
"U" or digital type pressure gauge in the pressure socket
upstream of the gas valve and sub se quent ly closing the
boiler shutoff valve (cock) and closing the gas valve, no
IE
pressure variation must occur in the next fi ve minutes on
the gauge.

N.W.: Pressure values specifi ed in the table indicate the dif-
ference of pressure values between the gas valve outlet and
the combustion chamber. Ad just ments are therefore carried
out with the diff erential pressure gauge ( "U" or digital type)
with the sensors inserted in the test pressure outlet of the
modulating adjustable gas valve and on the sealed chamber

- Ensure activation of the device for protection against the
ionisation fl ame control gas; ac ti va tion time must be less
than ten seconds.
- Visually inspect to check for leakage of water or oxidation
of relative couplings.
- Check visually that the water safety drain valve is not
blocked.
- Check that the charge of the expansion vessel af ter dischar-
ging system pressure to the zero set ting (check via boiler
pressure gauge), is at 1 bar.
- Check that the system static pressure (in cold con di tions
and after system recharging via the fi lling valve ) is between
1 and 1,2 bar.
- Check visually that the safety and control devices have not
been tampered with and/or shorted, in par tic u lar:
- temperature safety thermostat;
- air pressure switch.
- Ensure correct maintenance and condition of the electrical
installation with particular reference to:
- electrical cables must be inside the channels;
- no traces of black marking or burns.
