3.14 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
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.
- 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 posi-
tioned outside of the boiler;
- system control thermostat intervention;
- domestic hot water control thermostat inter-
vention.
- 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,
- water pressure switch.
- 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.

3.15 VARIABLE HEAT OUTPUT.
NOTE:
the pressures indicated in the tables
represent the difference in existing pressures
between the gas valve outlet and the combustion
chamber. The adjustments should therefore,be
carried out using a differential manometer
(small "U"-shaped column or digital manometer)
with the probes inserted in the pressure test gas
valve outlet and on the sealed chamber positive
pressure test. The power data given in the table
is obtained with 0.5m long intake/exhaust pipe.
Gas flow rates refer to heating power below a
temperature of 15°C and pressure of 1013 mbar.
Burner pressure values refer to use of gas at 15°C.
