LIMITATIONS OF USE
THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY
CONNECTED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO
BE CONSIDERED IMPROPER AND THEREFORE DANGEROUS.
THE USER MUST GUARANTEE THE CORRECT FITTING OF THE APPLIANCE, ENTRUSTING THE INSTALLATION OF IT
TO QUALIFIED PERSONNEL AND HAVING THE FIRST COMMISSIONING OF IT CARRIED OUT BY A SERVICE CENTRE
AUTHORISED BY THE COMPANY MANUFACTURING THE BURNER.
A FUNDAMENTAL FACTOR IN THIS RESPECT IS THE ELECTRICAL CONNECTION TO THE GENERATOR’S CONTROL
AND SAFETY UNITS (CONTROL THERMOSTAT, SAFETY, ETC.) WHICH GUARANTEES CORRECT AND SAFE FUNCTIO-
NING OF THE BURNER.
THEREFORE, ANY OPERATION OF THE APPLIANCE MUST BE PREVENTED WHICH DEPARTS FROM THE INSTALLA-
TION OPERATIONS OR WHICH HAPPENS AFTER TOTAL OR PARTIAL TAMPERING WITH THESE (E.G. DISCONNEC-
TION, EVEN PARTIAL, OF THE ELECTRICAL LEADS, OPENING THE GENERATOR DOOR, DISMANTLING OF PART OF
THE BURNER).
NEVER OPEN OR DISMANTLE ANY COMPONENT OF THE MACHINE.
OPERATE ONLY THE MAIN SWITCH, WHICH THROUGH ITS EASY ACCESSIBILITY AND RAPIDITY OF OPERATION
ALSO FUNCTIONS AS AN EMERGENCY SWITCH, AND ON THE RESET BUTTON.
IN THE EVENT OF REPEATED LOCKOUTS, DO NOT PERSIST WITH THE RESET BUTTON AND CONTACT QUALIFIED
PERSONNEL WHO WILL PROCEED TO ELIMINATE THE MALFUNCTION.
WARNING: DURING NORMAL OPERATION THE PARTS OF THE BURNER NEAREST TO THE GENERATOR (COUPLING
FLANGE) CAN BECOME VERY HOT, AVOID TOUCHING THEM SO AS NOT TO GET BURNT
OPERATION
z
Choose the fuel with the switch B in Fig. 19, located on the burner casing.
z
Turn on the power supply with the main switch A in Fig. 19.
z
Check the flame control device is not lock, eventually release it by means of the pushbutton located on the hole on the bur-
ner casing.
z
Check the series of thermostats (or pressure switches) enable the burner to operate.
z
The start cycle of the burner begins, the flame controller starts the burner fan and meanwhile energizes the ignition transfor-
mer.
z
At the end of the pre-purge, the solenoid valve of the selected fuel and the ignition transformer are both energized and the
burner starts.
z
The ignition transformer remains in operation for any seconds after the flame appears (post-ignition time) and after this time
it is sutted off.
ONLY BURNERS HS18: at the end of the safety time the flame controller energizes the second light oil solenoid valve.
