LIGHT OIL OPERATION
Pump
Delivery pressure must correspond with the table on pag. 19.
The depression must be less than 0.45 bar
Unusual noise must not be evident during pump operation
If the pressure is found to be unstable or if 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 meas-
ure permits the cause of the anomaly to be traced to either the
suction line or the pump.
If the problem lies in the suction line, check to make sure that the
filter is clean and that air is not entering the piping.
Filters (Fig. 42)
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 every year during regular
maintenance operations.
Do not clean the nozzle openings; do not even open them.
Flexible hoses
Check to make sure that the flexible hoses are still in good con-
dition.
Fuel tank
Approximately every 5 years, or whenever necessary, suck any
water or other impurities present 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
Assistant and have him carry out the necessary adjustments.
