LIMITATIONS OF USE
THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY CON-
NECTED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO BE CONSI-
DERED 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 AUTHORI-
SED 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
1
Turn to the “ON” position the main switch
A
, on the burner’s control panel (see Fig. 29).
2
Check the control box is not locked (LED
B
, on) and eventually release it by means of the pushbutton
C
(reset - for more informa-
tion about the device, please refer to the manual’s Appendix).
3
Check the series of thermostats or pressure switches gives the burner the start signal for operating (closed contact).
4
Check that the gas pressure in the gas network is sufficient (if the pressure is normal, the LED
E
lights up).
5
The gas proving system checking cycle starts: the proving system
LC
LED lights up when the cycle ends.
6
The fan motor starts, the servocontrol drives the air damper to the maximum opening position (LED
G
on); the pre-purge time
countdown starts now.
7
At the end of the pre-purgue time, the air damper moves to the ignition position (about 5°), the ignition transformer is energised
(LED
I
on), the solenoid gas valves
EV1
and
EV2
are energised (LEDs
L
and
M
on). As far as burners with pilot gas train, the pilot
gas valves open.
8
The flame must lights up within few seconds after the gas valves opening, otherwise the control box locks out. Few seconds after
ATTENTION:
before starting the burner up, be sure that the manual cutoff valves are open and check that the pres-
sure upstream the gas train complies the value quoted on paragraph “Technical specifications”.
