Airflow control

The combustion air is regulated at two
points:
· On the pressure side by means of the
opening gap between the turbulator
and burner tube.
· On the suction side by means of the
air flap actuated by servomotor Y10.
Airflow control in the burner head
has an effect on the air quantity, as well
as on the mixing zone and the air
pressure in the burner tube. Turn
