Pump
The delivery pressure must be stable.
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 mea-
sure permits the cause of the anomaly to be traced to either the
suction piping or the pump.
If the pump is found to be responsible, check to make sure that
the filter is not dirty. The vacuum meter is installed upstream from
the filter and consequently will not indicate whether the filter is
clogged or not.
Contrarily, 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.
Flexible hoses
Check to make sure that the flexible hoses are still in good con-
dition and that they are not crushed or otherwise deformed. Che-
ck periodically the flexible pipes conditions. Using kerosene, they
have to be replaced at least every 2 years.
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.
Filters
Check the following filter boxes:
• on fuel supply line;
• in the pump;
and clean or replace as required.
If rust or other impurities are observed inside the pump, use a se-
parate pump to lift any water and other impurities that may have
deposited on the bottom of the tank. Then clean the insides of the
pump and the cover sealing surface.
Nozzles
Do not clean the nozzle openings; do not even open them.
Combustion must be checked after the nozzles have been chan-
ged.
Combustion head
Check to make sure that all the parts of the combustion head are
in good condition, positioned correctly, free of all impurities, and
that no deformation has been caused by operation at high tem-
peratures.
Flame detector
Clean the flame detector.
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
Leave the burner working without interruptions for 10 min. and set
rightly all the components stated in this manual.
Then carry out a combustion check verifying:
• smoke temperature at the chimney;
• content of CO 2 (%);
• content of CO (ppm);
• smoke value according to opacity smokes index according to
Bacharach scale.
