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 recommended 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.
The hoses supplied with this burner are not
suitable for use with light oil containing a bio
blend.
WARNING
In case of use with light oil containing up to 30%
bio blend, it will be essential to use flexible oil lines
suitable for biofuel use.
Please contact the manufacturer for further
information.
Air damper
Inside the suction casing 2)(Fig. 27) there is a damper that opens
due to the effect of the depression generated when operating.
The device interrupts the natural flow of air from the burner to the
boiler and vice-versa during stop phases.
It is important to periodically check the device and clean if there
are accumulations of dust that can obstruct the regular opening
and closing of the damper.

Maintenance
Fuel tank
If water or contamination is present within the fuel tank, it is es-
sential that this is removed before the equipment is to be used.
This is extremely important when light oil containing bio diesel is
in use. If in doubt about how to achieve this then please contact
the fuel or oil tank supplier.
Cleaning the 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
WARNING
polluting combustion.
When performing these operations, take care not
to damage the fan.
Proceed as follows:
unscrew the screws 1)(Fig. 27) and take out the air damper
2);
loosen the screws 3) and take out the suction inlet 4);
clean the fan and the inside of the suction inlet, using a suit-
able brush and compressed air.
If necessary, carefully disassemble the fan (Fig. 28).
It is essential to respect position B)(Fig. 28), indi-
cated in the table.
WARNING
When reinstalling, follow the above indications in reverse order;
