MAINTENANCE
Analyse combustion gases and check that the emission values are
correct at least once a year, in compliance with current law.
• Clean air dampers, the air pressure switch with pressure port and
the relevant pipe (if fitted).
• Check the electrode condition. Replace them, if necessary.
• Have the burner and the chimney cleaned by specialised personnel
(stove repairer); a clean burner is more efficient, lasts longer and
is quieter.
• Check that the fuel filter is clean. Replace it, if necessary.
• Check that all components of the combustion head are in good
condition, have not been deformed and are free from deposits
deriving from the installation environment and/or from poor
combustion.
• In order to clean the combustion head, its outlet and components
must be disassembled. Be careful during the reassembly operations
to exactly centre the gas diffuser with respect to the electrodes,
making sure that they are not earthed, which would result in the
locking of the burner. Verify also that the ignition electrode spark
takes place exclusively between itself and the perforated sheet
metal disk (see combustion head and electrode disk distance
regulation diagram) for the version without pilot.
If it is necessary to clean the combustion head, remove its components
according to the procedure described below:
• Remove the holding nut and unhook the gas throttle control lever
-26.
• Unscrew the four screws -6 and turn the burner around the pin -10
inserted into the specific hinge (figure 1).
• After pulling out the ignition and ionisation cables -14 from the
terminals of the respective electrodes, unscrew completely the
nut -9 and tighten the screw -16, moving it forward inside the gas
delivery fitting -30 (figure 3), far enough to permit subsequent
dismantling of the mixing unit.
• With suitable wrench, loosen the screw -8 in the direction indicated
by the arrow, unhooking the lever that moves the combustion head
forward.
