LIGHT OIL OPERATION
Pump
The delivery pressure must comply with the table on page 29.
The depression must be less than 0.45 bar.
Unusual noise must not be evident during pump operation.
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 (Fig. 38)
Check the filtering baskets on line 1) and at nozzle 2) 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.

Nozzles
It is advisable to replace nozzles once a year during periodical
maintenance.
Do not clean the nozzle openings.
Hoses
Check that these are in good conditions.
Fuel tank
Approximately every 5 years, suck any water on the bottom of the
tank using a separate pump.
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 Service in order to carry out the necessary adjustments.
