The diagrams are intended asmere guidelines and are based ontest boilers complying withcurrent regulations.In reality, variations may occur,due to the following factors:a) the ability of the burner to
overcome the excess pressuregenerated upon lighting (not strictly linked to thatapplying during normaloperation) which tends to varyfrom one boiler to another;
b) high thermal load in furnace(ratio between thermal powerof furnace and relevant volume- kcal/h/m3) which may preventthe burner fan from exploitingthe entire operating range.

• Manual air flow adjustment.• Equipped with one flange and one insu-
lating seal for boiler fastening, 2 flexiblehoses, one line filter and one nozzle.
• On request: a device for air gate closureduring pause to avoid loss of heat upflue.
• Flame detection by photoresistance.• Control panel including stop/go switch,
operation and block indicators, heatingelement operation light.
• Terminal block for the electrical and ther-mostatic connections to the burner.
• Electrical protection rating IP40.

TWO-STAGE
EXTRA HEAVY OIL BURNERS
The diagrams are intended asmere guidelines and are based ontest boilers complying withcurrent regulations.In reality, variations may occur,due to the following factors:a) the ability of the burner to
overcome the excess pressuregenerated upon lighting (not strictly linked to thatapplying during normaloperation) which tends to varyfrom one boiler to another;
b) high thermal load in furnace(ratio between thermal powerof furnace and relevant volume- kcal/h/m3) which may preventthe burner fan from exploitingthe entire operating range.

the kit (to be order separately) consi-sting of: specific line filter, stainlesssteel flexible hoses and resistors forpump and pressure regulator valve.
• On request it is possible to add to theburner a supplementary heavy oil pre-heater using steam, which means thefuel can be heated by the steam fromthe boiler to provide an energy saving.
• Equipped with one flange and one insu-lating seal for boiler fastening, 2 flexi-ble hoses and one line filter; nozzle notincluded, to be ordered separatelydepending on the required flow.
• On request: steam pre-heater.
CONSTRUCTION CHARACTERISTICSThe burner consists of:• Light aluminium alloy fan part.• High performance centrifugal fan.• Combustion air intake with air flow
adjustment device.• Sliding boiler coupling flange to adapt
the head protrusion to the various types
of boilers.• Adjustable blast-pipe with stainless
steel nozzle and deflector disk in steel.• A three-phase electric motor to run fan
and another to run the pump.• Air pressure switch to ensure the pre-
sence of combustion air.• Electric servomotor with mechanical
cam for simultaneous regulation ofcombustion air and fuel.
• Gear pump with pressure regulator.• Atomisation unit with magnet to control
the outlet/nozzle return pins.• Electrical fuel preheater comprising
antigas valve, self-cleaning filter, thermometer, minimum and regulationthermostat; security thermostat excluded BT 120.
• Automatic control and command equip-ment for the burner compliant withEuropean standard EN230.
• Flame detection by photoresistance.• Control panel including stop/go switch,
1st/2nd stage selector, operation and
block indicators, heating element opera-tion light.
• Terminal block for the electrical andthermostatic connections to the burnerand to control the second stage of wor-king or for the connection of the electro-nic output regolator.
