MAINTENANCE
Analyse combustion gases and check that the emission values are
correct at least once a year, in compliance with current law.
Check the fuel filter: if it is dirty, replace it.
Check that all components of the combustion head are in good
condition, have not been deformed by high temperatures and contain
no impurities or deposits from the installation environment or from
poor combustion; check the efficiency of electrodes.
If it is necessary to clean the combustion head, take out its
components according to the procedure described below:
Unscrew the two screws (2) and turn the burner around the pin (1)
in the hinge.
After pulling out the ignition and ionisation cables (3) from the
terminals of the respective electrodes, unscrew completely the
nut (4) and tighten the screw (5), moving it forward inside the gas
delivery fitting (8) far enough to permit subsequent dismantling of
the mixing unit. With the same wrench turn the ball joint (6) in the
direction indicated by the arrow, unhooking the lever that moves the
combustion head forward.
Slightly raise the gas delivery fitting (8) and remove the entire mixing
unit in the direction indicated by the arrow (9). Having completed
the maintenance works, refit the combustion head, following in
reverse order the operations described above, after having checked
the correct position of the ignition and ionisation electrodes (see
0002934691).
When closing the burner, gently pull towards the
!
electrical panel, putting the two ignition and ionisation
cables slightly in tension, then arrange them into their
housings (7) as in figure 2. This will ensure that the two
cables do not get damaged by the fan during burner
operation.
