Yearly appliance check and maintenance.
The following checks and maintenance should be performed at least once
ES
a year.
- Clean the fume side of the heat exchanger.
- Clean the main burner.
TR
- Visually check the fume extractor hood for wear or corrosion.
- Check correct ignition and operation.
- Check correct setting of the burner in domestic hot water and heating
RO
phases.
- Check correct operation of appliance control adjustment devices, in
particular:
IE
- activation of the electrical main switch on the boiler;
- activation of the system control thermostat;
- activation of the domestic hot water control thermostat.
- Check the tightness of the gas circuit section between the appliance
on/off valve (cock) and gas valve (cut out). Inserting a "U" type or
differential digital pressure gauge in the pressure point ahead of the gas
valve and subsequently closing the boiler on/off valve (cock) and closing
the gas valve, after 5 minutes there must be no pressure variation on the
gauge.
- Check activation of the device against no gas ionization flame control;
intervention time must be less than ten seconds.
- Visually check for water leaks or oxidation in relative couplings.
- Check visually that the water safety drain valves are not blocked.
- Make sure that after discharging system pressure and bringing it to the
zero (read on boiler pressure gauge), the expansion tank charge is 1.0
bar.

- Check that the system static pressure (with system cold and after system
recharging via the filler cock) is between 1 and 1.2 bar.
- Visually check that the safety and control devices have not been tampered
with and/or shorted, in particular:
- overtemperature safety thermostat;
- system pressure switch;
- fume pressure switch.
- Check correct maintenance and good condition of the electrical system
and in particular:
- electrical feed wires must be inside the whipping;
- there must be no traces of blackening or burning.
