•
Comburent air intake with throttle gate for the regulation of the air
flow rate.
•
Sliding generator connection flange to adapt the head protrusion to
the various types of heat generators.
•
Air pressure switch to ensure the comburent air presence.
•
Main gas train in EC version consisting of an operating and safety
valve with electro-magnetic operation, minimum pressure switch,
pressure regulator and gas filter.
•
Flame detection by means of ionisation electrode.
•
Automatic burner command and control equipment according to
European standard EN298.
•
Display showing the operating sequence and error code in the
event of a lockout.
