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 airfl ow. Therefore, it is always
necessary to fi ne-tune airfl ow using the burner’s airfl ow 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 airfl ow, turn the
airfl ow knob lever. The extent to which the airfl ow 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 airfl ow and anticlockwise to
decrease airfl ow.
