DESIGN CHARACTERISTICS
Burner with low NOx and CO/O2 emissions in accordance with
European standard EN676
• Low NOx and internal recirculation combustion head with stainless
steel nozzle.
• Mounting flange to the sliding generator, to adapt the protuberance
of the head to various types of heating generators.
• Control panel complete with operation mimic panel and indicator
lights.
• Automatic burner command and control equipment with
microprocessor in compliance with European standard EN298
integrated with valve seal control.
• Display showing the operating sequence and error code in the event
of a lockout.
• Flame detection by means of ionisation electrode.
• Flame inspection glass.
• Three-phase electric motor to run fan.
• Main gas train in EC version consisting of an operating and safety
valve with electro-magnetic operation, valve seal control, minimum
and maximum pressure switch, pressure regulator and gas filter.
• Intelligent connection between boiler and gas train (fail safe).
¹) NATURAL GAS EMISSIONS
Classes defined according to EN 676 standards.
Class NOx emissions in mg/kWh natural gas
1 ≤ 170
2 ≤ 120
3 ≤ 80
4 ≤ 60
Propane / natural gas CO emissions ≤ 100 mg/kWh
TECHNICAL FUNCTIONAL CHARACTERISTICS
• Operation at two progressive stages / modulating.
• Ability to operate with output modulation by means of automatic
regulator mounted on the control panel (to be ordered separately
with the modulation kit).
• Fuel / combustion air flow rate regulation by means of two
servomotors controlled by the electronic equipment.
• 7-pole connectors for the auxiliary power supply and thermostat
connection, 4-pole connector for connecting the power electronic
regulator.
• High fan output, low electrical input, low noise.
• Modulation ratio ≥1:5.
• Hinge opening on both sides for easy access to the combustion
head when burner is installed.
• Air minimum and maximum flow rate regulation by means of electric
stepper servomotor with pause closure of damper to prevent any
heat dispersion to flue.
• Electrical system with protection rating IP40.IP20.
• Possibility of mounting the gas ramp in up or down position compared
to the head group.
