Maintenance
7.1 Notes on safety for the maintenance
The periodic maintenance is essential for the good operation,
safety, yield and duration of the burner.
It allows you to reduce consumption and polluting emissions and
to keep the product in a reliable state over time.
Before carrying out any maintenance, cleaning or checking oper-
ations:
7.2 Maintenance programme
7.2.1 Maintenance frequency
7.2.2 Checking and cleaning
Combustion
Carry out an analysis of the combustion discharge gases.
Significant differences with respect to the previous check indicate
the points where more care should be exercised during mainte-
nance.
Combustion head
Open the burner and make sure that all components of the
combustion head are in good condition, not deformed by the
high temperatures, free of impurities from the surroundings
and correctly positioned.
Fan
Check to make sure that no dust has accumulated inside the fan
or on its impellers, as this condition will cause a reduction in the
air flow rate and provoke polluting combustion.
Voltage on the QRI cell
Min value for a good work: 25 mV.
If the value is lower, it could be due to:
-
cell not positioned correctly
- bad regulation of the burner.
Burner
Clean the outside of the burner.
Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics in-
tact, especially: the flue gas temperature and combustion cham-
ber pressure.
Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
Combustion
In case the combustion values found at the beginning of the inter-
vention do not respect the standards in force or, in any case, do
not correspond to a proper combustion, contact the Technical As-
sistance Centre in order to carry out the necessary adjustments.

7 Maintenance
DANGER
The maintenance interventions and the calibration
of the burner must only be carried out by qualified,
authorised personnel, in accordance with the con-
tents of this manual and in compliance with the
standards and regulations of current laws.
DANGER
Turn off the burner's electrical supply using the
main system switch.
DANGER
Turn off the fuel interception tap.
Wait for the components in contact with heat
sources to cool down completely.
The gas combustion system should be checked at
least once a year by a representative of the man-
ufacturer or another specialised technician.
The operator must use the required equipment
during maintenance.
