SUGGESTIONS FOR CORRECT OPERATION
-
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 proper operation of electrodes.
If it is necessary to clean the outside of the combustion head, take
out its components according to the procedure described below:
- remove the holding nut and unhook the gas butterfly valve
control lever (1).
- unscrew the two screws (2) and turn the burner around the pin
(3) in the hinge (figure 1).
- 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), causing it to move forward
inside gas outlet connector (8) in figure 3 to a sufficient amount
to ensure successful disassembly of the mixing unit.
- With the same wrench turn the ball joint (6) in the direction
indicated with the arrow, unhooking the lever that moves the
combustion head forward (figure 2).
- Slightly raise the gas delivery connection (8) (figure 3) and
remove the entire mixing unit in the direction indicated by the
arrow in figure 4.
- Having completed the maintenance work, replace the combustion
head, following in reverse order the operations described above,
after having checked the correct position of ignition and ionisation
electrodes.
When closing the burner, gently pull towards the electrical
panel, putting the two ignition and ionisation cables slightly in
tension, then arrange them in their housings (7) as in figure
2. This will ensure that the two cables do not get damaged by
the fan during the operation of the
burner.
