USE OF THE BURNER
The burner is a fully automatic burner; it is activated by closing the isolating switch and the control box switch;
Burner operation is controlled by control and monitoring devices as stated in the chapter “Description of operation”.
The “lock-out” position is a safety position automatically taken up by the burner when a burner component or the
electric equipment is inefficient; before connecting the “released” burner again, it is good practice to make sure that
no defects exist in heating plant. The burner can remain in a lock-out” position without any time limit. To reset the
burner, press the appropriate push-button. “Lock-out” can be caused also by transient flaws (a little water in the fuel,
air in the pipes, etc.); if reset, the burner will start up normally. When “lock-out” occur repeatedly do not try to start,
first check if there is fuel in the tank and then call the local service to repair the defect.
MAINTENANCE
The burner requires no special maintenance, but it is good practice to perform the following operation at least at the
end of heating season:
1) Remove and throughly wash with solvents (petrol, trichoethylene, oil) the filters, the nozzles, the turbolator disk
and the ignition electrodes. When cleaning the nozzle, avoid using metal tools (use wood or plastic).
2) Clean the photoresistant-cell.
3) Have the boiler cleaned and also the chimney if necessary.
Remarks: The nozzle or nozzles should be replaced at least every two heating season. It may be necessary to
perform such operation more frequently.
