DESIGN CHARACTERISTICS
Burners are composed by:
•
Combustion head complete with stainless steel nozzle.
•
Mounting flange to the sliding generator, to adapt the
protuberance of the head to various types of heating generators.
•
Combustion air inlet equipped with sound insulation material,
designed to optimize the air flow to the air gate, (not provided
in the TBG 260 ME).
• 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

≤ 170
2
≤ 120
3
≤ 80
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.
•
Combustion head with partial recycling of exhaust gasses at
low NOx emissions (class II).
•
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.
•
Possibility of mounting the gas ramp in up or down position
compared to the head group.
