3.16 VARIABLE HEAT OUTPUT.
- Check the function of the electrode.
- Check the condition and integrity of the elec-
trical system and in particular:
- electrical power cables must be inside the
fairleads;
- there must be no traces of blackening or
burning.
Note:
in addition to yearly maintenance, one
must also check the thermal system, with
frequency and procedures that comply with the
indications of the technical regulations in force.
- Check sealing efficiency of gas circuit and the
internal system.
- Check the intervention of the device against no
gas ionisation flame control. Intervention time
must be less than 10 seconds.
- Visually check for water leaks or oxidation
from/on connections.
- 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 vessel load is at 1.0 bar.
- Check that the system static pressure (with
system cold and after refilling the system by
means of 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;
- water pressure switch;
3.15 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
The following checks and maintenance should
be performed at least once a year.
- Check that the system's water PH is between 7
and 8.5.
- Clean the flue side of the heat exchanger.
- Clean the main burner.
- Visually check the flue hood for deterioration
or corrosion.
- Check correct lighting and operation.
- Ensure correct calibration of the burner in
domestic water and heating phases.
- Check correct operation of control and
adjustment devices and in particular:
- intervention of main electrical switch positi-
oned outside of the boiler;
- system control thermostat intervention;
- domestic hot water control thermostat inter-
vention.
