Maintenance
Pump
The delivery pressure must be 25 bar.
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 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. 45)
Check the filtering baskets on line 1) and at nozzle 2) present in
the system. Clean or replace if necessary. If rust or other impuri-
ties 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.

Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
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.
