PART II - OPERATION
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 FUNCTIONING OF THE BURNER.
THEREFORE, ANY OPERATION OF THE APPLIANCE MUST BE PREVENTED WHICH DEPARTS FROM THE
INSTALLATION OPERATIONS OR WHICH HAPPENS AFTER TOTAL OR PARTIAL TAMPERING WITH THESE (E.G.
DISCONNECTION, 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 CASE OF A BURNER SHUT-DOWN, RESET THE CONTROL BOX BY MEANS OF THE RESET PUSHBUTTON. IF A
SECOND SHUT-DOWN TAKES PLACE, CALL THE TECHNICAL SERVICE, WITHOUT TRYING TO RESET FURTHER.
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
CAUTION: before starting the burner up, be sure that the manual cutoff valves on the
feeding line and on the return are open. Be that the mains switch is closed.
Read carefully the “WARNINGS” chapter in this manual.
Startup the burner by the boiler's master power switch;
as for double-stage models, turn the burner main switch A to On;
make sure that the control box has not shut down and reset if necessary using the reset button pressing the clear
rubber seal on the burner cover;
make sure that the set of thermostats (or pressure-switches) triggers burner operation (in double-stage models L1
LED lights on)
the burner starting cycle begins: the control box switches on the burner's fan, the ignition transformer switches on at
the same time (in double-stage models LT LED lights on);
at the end of the pre-purge time, the light oil solenoid valve is powered and the burner starts up;
the ignition transformer stays on for a few seconds after the ignition of the flame (post-ignition time) and at the end of
this time it is switched off.
Double-stage burners: after the start-up, the burner remains in the low flame operation (in double-stage models, L1
on) or switches to the high flame stage (in double-stage models, L2 on), according to the plant needs.
