3.19 Yearly appliance check and servicing.
The following checks and maintenance should be performed at least once
ES
a year.
- Clean the flue side of the heat exchanger.
- Clean the main burner.
PL
- Check correct lighting and operation.
- Ensure correct calibration of the burner in domestic water and heating
phases.
TR
- Check correct operation of control and adjustment devices and in par-
ticular:
- intervention of electrical main electrical switch on boiler;
CZ
- system control thermostat intervention;
- domestic water control thermostat intervention.
SI
- Check that the internal system is properly sealed according to specifica-
tions.
- Check intervention of the device against no gas ionization flame con-
trol:
HU
- ensure intervention time is less than ten seconds.

N.B.: the pressures given in the table indicate the differences in pressure at
the ends of the mixer Venturi and measurable at the pressure points at the
top of the sealed chamber (see pressure test 16 and 17 page 193+). Adjust-
ments must therefore be made with a digital differential pressure gauge
having a scale in tenths of mm or Pascal. The power data given in the table
is obtained with intake/exhaust pipe of length 0.5 m. Gas flow rates refer
to heat power below temperature of 15°C and at a pressure of 1013 mbar.
Burner pressure values refer to use of gas at 15°C.

- Visually check for water leaks or oxidation from/on connections and
traces of residual condensation inside the sealed chamber.
- By means of the condensate drain plug check for any residual material
possibly blocking the flow of condensate.
- Check contents of the condensate drain trap.
- Visually check that the water safety drain valve is not blocked.
- Check that, after discharging system pressure and bringing it to zero (read
on boiler pressure gauge), the expansion tank charge is at 1.0 bar.
- Check that the system static pressure (with system cold and after refilling
the system by means of the filler cock) 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;
- Check the condition and integrity of the electrical system and in par-
ticular:
- electrical power cables must be inside the whipping;
- there must be no traces of blackening or burning.
