LIMITATIONS OF USE
THE BURNER IS AN APPLIANCE DESIGNED AND CONSTRUCTED TO OPERATE ONLY AFTER BEING CORRECTLY CONNEC-
TED TO A HEAT GENERATOR (E.G. BOILER, HOT AIR GENERATOR, FURNACE, ETC.), ANY OTHER USE IS TO BE CONSIDE-
RED 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
Turn to the “ON” position the main switch on the burner control panel.
Check the control box is not locked and eventually release it by means of the reset pushbutton (for further information about the ,
please refer to the manual’s Appendix).
Check the series of thermostats or pressure switches enables the burner to operate.
Check that the gas pressure in the gas network is sufficient.
The check cycle of the gas proving system starts; the end of this check is signalled by the related light on the device (see page 25).
To unlock the system, press the reset pushbutton on the gas proving system.
The fan motor starts, the servocontrol drives the air damper to the maximum opening position; the pre-purge time countdown starts
now.
At the end of the pre-purgue time, the air damper moves to the ignition position (about 5°), the ignition transformer is energised, the
solenoid gas valves
EV1
and
EV2
are energised.
The flame must appear within few seconds after the gas valves opening, otherwise the control box locks out. Some seconds after
the gas valves opening the ignition transformer turns off.. The burner is now on and at the same time the actuator drives itself to the
high flame position (90° - see pag. 26).
Some seconds after the gas valves opening, the burner starts the automatic operation: it works in high or low-flame operation (for
progressive PR- burners) or in the phase requested by the burner modulator (Fully modulating - MD buners) according to the requi-
rements of the plant.
ATTENTION: BEFORE STARTING THE BURNER UP, BE SURE THAT THE MANUAL CUTOFF VALVES ARE OPEN
AND CHECK THAT THE PRESSURE VALUE UPSTREAM THE GAS TRAIN MATCHES THE VALUE ON PARAGRAPH
“TECHNICAL SPECIFICATIONS”). CHECK THAT THE MAINS SWITCH IS CLOSED. CAREF
