Annual maintenance procedures
The following checks and maintenance should be performed at least once a year.
- Clean the flue side of the heat exchanger.
- Clean the main burner.
- Make a visual inspection of the flue extraction hood for wear or corrosion.
- Ensure correct ignition and operation.
- Ensure correct settings of the burner in domestic water and heating modes.
- Verify correct operation and adjustment of the boiler, in particular:
- operation of the electrical main switch on the boiler;
- operation of the system control thermostat;
- operation of the domestic water control thermostat or sensor.
- Ensure gas soundness of the gas intake circuit; insert a “U” or digital type pressure gauge in the pres-
sure
test point upstream of the gas valve and then close the boiler shutoff valve. No pressure variation must
occur in the next five minutes on the gauge.
- Ensure activation of the device for protection against the ionisation flame control gas; activation time
must
be less than ten seconds
- Visually inspect to check for leakage of water or oxidation of fittings.
- Check visually that the water safety valve outlets are not blocked and that the tundish is clear.
- Check that the charge of the expansion vessel after discharging system pressure to the zero setting
(check via boiler pressure gauge) is at 1,0 bar.
- Check that the system static pressure (in cold conditions and after system recharging via the filling
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
particular:
- temperature safety thermostat;
- air pressure switch.
- Ensure correct maintenance and condition of the electrical installation with particular reference to:
-electrical cables must be correctly routed
-no traces of black marking or burns
