USING THE BURNER
The burner operates completely automatically; when the main switch and that on control panel are turned off, the
burner is turned on. The burner is operated by the command and control devices, as described in the chapter
“Description of operation”. The “cut-out” position is a position of safety that the burner goes to automatically when
some part of the burner or the system is not working properly. Before “resetting” the burner to activate it again, it
is advisable to check that there are no faults in the heating system.
The burner can stay in the shut down (cut-out) position for an unlimited time.
To reset it, press the special pushbutton (reset). Cut-outs can also be caused by temporary irregularities. When
this occurs, once the burner is reset it starts without any problem.
When the burner cuts out repeatedly (3 - 4 times) do not continue trying to reset it. Make sure fuel is reaching the
burner, and contact the local Assistance Service to correct the fault.
MAINTENANCE
The burner does not require any particular maintenance; however, it is a good rule to carry out the following
operations, at least at the end of the heating season:
1) For burners that use gas oil, remove and carefully clean the following with a solvent (petrol, trichloroethane,
petroleum): filters, nozzle, swirl disc, ignition electrodes. Do not use metal instruments to clean the nozzle
(use wood or plastic).
2) Clean the photocell.
3) Have the boiler and, if necessary, the flue cleaned by specialised personnel (boiler repairer). A clean boiler
offers a higher efficiency, lasts longer, and is quieter.
4) For gas burners, regularly make sure the gas filter is clean.
5) To clean the combustion head, all the inlet components must be removed. When reassembling the unit,
carefully centre the gas outlet head in relation to the electrodes, in order to avoid these earthing, which will
result in the burner cutting out. Also check that the spark from the ignition electrode only passes between the
electrode and the perforated metal disc.
