4.1.3 Insert control
The burner is equipped with a lever that changes the position of the brake
plate in the burner tube. This is used to set the correct pressure drop across
the combustion assembly, thereby obtaining good combustion without
pulsation.
The setting to be used depends on, among other things, the output settings
and overpressure in the boiler
Setting the brake plate
• Small column: turn the screw left
• Large column: turn the screw right
Setting the brake plate position affects airflow. Therefore, it is always
necessary to fine-tune airflow using the burner’s airflow regulator.
4.1.4 Air intake adjustment
Setting the air intake is very important to achieve good combustion with
neither too much nor too little air. To adjust the combustion airflow, turn the
airflow regulator lever using an Allen key. The extent to which the airflow
lever must be open is determined by the heat output and overpressure in
the boiler as well as other settings on the burner such as the position of the
brake plate.
4.1.5 Setting the air quantity
Turn the air intake clockwise to increase airflow and anticlockwise to
decrease airflow.
