MAINTENANCE
Carry out periodic analysis of the exhaust combustion gas, che
-
cking the emissions.
Periodically replace the gas filter when dirty.
Check that all the components of the combustion head are in a
good state, not deformed by the temperature and free from im
-
purities or deposits from the installation environment or by poor
combustion and check also the electrodes are working efficiently.
If the combustion head needs to be cleaned, remove the compo-
nents following the procedure indicated below:
Unscrew the two screws (2) and turn the burner around the pin (1)
in the hinge (figure 1).
After pulling out the ignition and ionisation cables (3) from the ter-
minals 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 indica
-
ted with the arrow, unhooking the lever that moves the combustion
head forward (figure 2).
Slacken, by means of a socket head screw of 3 mm (a) the M6
screw (b) that secures the air pressure pipe (c) inside the tube unit
and then remove it from its position.
Slightly raise the gas outlet connector (8) (figure 3). and pull out
the whole mixing assembly in the direction indicated by the arrow
(9) in figure 4. Complete maintenance operations, proceed with re-
assembly of the combustion head, following the above instructions
in reverse order, after having checked the correct position of the
ignition and ionisation electrodes (see 0002934690).
Note: important
On closing the burner, gently pull towards the electrical panel, put
-
ting them slightly in tension, the two ignition and ionisation cables,
and then arrange them in their places (7) as in figure 2. This will
ensure that the two cables do not get damaged by the fan during
the working of the burner.
