6.1
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 op-
erations:

Maintenance programme
6.2.1
Maintenance frequency
The gas combustion system should be checked
at least once a
year
by a representative of the manufacturer or another
specialised technician.
6.2.2
Checking and cleaning
Combustion
The optimum calibration of the burner requires an analysis of the
flue gases. Significant differences with respect to the previous
measurements indicate the points where more care should be
exercised during maintenance.
Gas leaks
Make sure there are no gas leaks on the conduit between the
gas meter and the burner.
Gas filter
Replace the gas filter when it is dirty.
Flame inspection window
Clean the glass of the flame inspection window.
Combustion head
Open the burner and make sure that all the components of the
combustion head are:
– undamaged
– not deformed due to high temperature
– free of ambient dirt or dust
– free of rusted materials
– adequately positioned
Make sure that the gas outlet holes for the start-up, on the com-
bustion head distributor, are free of dirt or rust deposits.
In case of doubt, disassemble the elbow 5)(Fig. 37).
Combustion
Adjust the burner if the combustion values found at the begin-
ning of the operation do not comply with the regulations in force
or, at any rate, do not produce good combustion.
Use the appropriate card to record the new combustion values;
they will be useful for subsequent controls.
