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.
