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.
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
DANGER
standards and regulations of current laws.

Maintenance programme

7.2.1

Maintenance frequency

The combustion system should be checked at
least once a year by a representative of the man-
ufacturer or another specialised technician.
7.2.2

Checking and cleaning

The operator must use the required equipment
during maintenance.
Combustion
The optimum calibration of the burner requires an analysis of the
flue gases.
Significant differences with respect to the previous measure-
ments indicate the points where most care should be exercised
during maintenance.
Combustion head
Open the burner and make sure that all components of the com-
bustion head are in good condition, not deformed by the high
temperatures, free of impurities from the surroundings and cor-
rectly positioned.
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.
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.

Maintenance
Before carrying out any maintenance, cleaning or checking oper-
ations:
Disconnect the electrical supply from the burner
by means of the main system switch.
DANGER
Turn off the fuel interception tap.
DANGER
Wait for the components in contact with heat
sources to cool down completely.
Pump
If the pressure is unstable, or the pump runs noisily, the flexible
hose must be detached from the line filter and the fuel must be
sucked from a tank located near the burner. This measure per-
mits the cause of the anomaly to be traced to either the suction
piping or the pump.
If the problem lies in the suction line, check the filter is clean and
that air is not entering the piping.
Filters
Check the filtering baskets on line and at nozzle present in the
system.
Clean or replace if necessary.
If rust or other impurities are observed inside the pump, use a
separate pump to lift any water and other impurities that may
have deposited on the bottom of the tank.
Hoses
 Check periodically the flexible pipes conditions. They have
to be replaced at least every 2 years.
 In case of use of gas oil and biofuel blends, it is strongly rec-
ommended to inspect even more frequently the hoses and
replace them where contamination has occurred.
 Check to make sure that the hoses are still in good condi-
tion.
In case of use with light oil containing bio blend, it
will be essential to use flexible oil lines suitable for
biofuel use.
WARNING
Please contact the manufacturer for further
information.
