LIGHT-OIL BURNERS TWO STAGES PROGRESSIVE OR MODULATING
FGP 650/M
Burners for light-oil two stages progressive (hi-low flame) or modulating (PID fully modulating) if equipped with
addition of optional modulation kit and probe.
They are composed by: fan at high pressurisation and combustion head with adjustment at high efficiency and high
flame stability.
Compact overall dimensions and disposition rationalized of the components with accessibility facilitated for the
operations of setting and maintenance.
The adoption of strong metal components makes the burner durable also in heavy duty conditions.
Complete of nozzle, flexible pipes and line filter.
Complete of flange and gasket for installation on generator.
Available with mechanical cam or with electronic cam.

The firing rates has been obtained based on test boilers in accordance with EN267 standards and are indicative of matching the burner to the boiler.
For the correct operation of the burner, combustion chamber dimensions must be in accordance with current regulation. In case of non-compliance,
contact the manufacturer.

PRODUCT SPECIFICATION
SHORT DESCRIPTION
Light-oil burners two stages progressive (hi-low flame) or modulating (PID fully modulating) if equipped with addition
of optional modulation kit and probe.
DETAILED SPECIFICATION
Light-oil burner two stages progressive (hi-low flame) or modulating (PID fully modulating) if equipped with addition
of optional modulation kit and probe; composed by:
• Frame made of steel;
• Centrifugal fan at high pressurization with reverse curved blades at low noisiness;
• Combustion head with adjustment at high performance and elevated flame stability equipped with inox steel blast tube and
steel flame disc;
• Easy extraction of combustion head without get off the burners by bolier;
• Flange and insulating gasket for fixing at boiler/furnace;
• Control box for control and supervision of burner;
• Photoresistance for flame detection;
• Three-phase power supply;
• Fan motor start-up made by delta/star system;
• IP40 electric protection level;
• Safety air pressure switch to stop the fuel pump in case of failed or anomalous fan operation, causing the lockout of the burner;
• Servomotor for air shutter and for the fuel pressure regulator;
• Mobile shutter with total closure when idle for minimize the energetic losses related at boiler cooling;
• Light-oil gear pump operated by specific electric motor;
• Nozzle assembly with magnet to control inlet/return needle nozzle;
• Maximum light-oil pressure switch to stop the burner in case of the light-oil pressure on the return is higher then the set point
value;
• Set up for the additional specific kit that transforms burner operation as modulating i.e.the modulating kit allows to supply any
power between the minimum and maximum value based on instantaneous loading request.
