Important
The burner should be serviced at least
once a year by a trained specialist.
· Turn off power supply at isolator
switch.
· Check absence of voltage.
· Close fuel input.
· Check for leaks;
Do not use: pressurized liquids or
chlorinated products.
The setting values are indicated in the
paragraph: "Start-up".
Use only original spare parts.
· Remove the burner housing.
Checking combustion components
· Take out the cell and wipe it with a
clean, dry rag.
· Disconnect the ignition cables from
the transformer and the oil tube.
· Unscrew the screws W on the cover
and turn (bayonet system) to release
the combustion components.
· Disconnect the electrode cables.
· Withdraw and clean the turbulator.
· Disassemble and change the nozzle
if necessary.
· Clean or, if necessary, change the
electrodes.
· Check their settings.
· If necessary, remove any dust from
the parts that are accessible from
the cover.
· Reassemble by performing the same
actions as during disassembly but in
reverse order.
Cleaning the air circuit

· Check pressure and absence of leaks.
Motor-driven pump unit
· Check:
– atomization pressure,
– absence of leaks in systems,
– coupling between pump and motor,
– state of flexible hoses.
Fuel-oil valves
The valves do not require any special
maintenance.
The valves must not be repaired.
Defective valves must be replaced by a
qualified specialist, who will then carry
out new checks for leaks, correct
running and combustion.
Checking connections
On the connection box, the fan motor
and the servomotor.
Cleaning the housing
· Clean housing with water and
detergent.
· Replace.
Remarks
After each intervention:
· Check combustion under actual
operating conditions (doors closed,
housing in place, etc.) and absence
of leaks in the different systems.
· Carry out the safety checks.
· Note the results in the appropriate
documents.
