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
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.
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
and 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. If in
doubt, disassemble the elbow (Fig. 41 at page 52).
Fan
Check to make sure that no dust has accumulated inside the fan
or on its blades, as this condition will cause a reduction in the air
flow rate and provoke polluting combustion.
Burner
Clean the outside of the burner.
Flame inspection window
Clean the glass of the flame inspection window (Fig. 38).
Gas leaks
Make sure that there are no gas leaks on the pipes between the
gas meter and the burner.
Gas filter
Replace the gas filter when it is dirty.
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.
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
Disconnect the electrical supply from the burner
by means of the main system switch.
DANGER
Close 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.
