7.3.2 Set air pressure switch
The switch point must be checked and if necessary adjusted during commission-
ing.
Connect pressure measuring device for differential pressure measurement.
Start the burner.
Carry out differential pressure measurement across the whole capacity range of
the burner and determine the lowest differential pressure.
Calculate switch point (80 % of release pressure or lowest differential pressure).
Set the switch point determined at the setting cam

.
Example
Lowest differential pressure
7.5 mbar
Switch point air pressure switch (80 %) 7.5 mbar × 0.8 = 6.0 mbar
Site specific influences on the air pressure, (e g. by the flue gas system, heat ex-
changer, installation location or air supply) may make it necessary to vary the set-
ting of the air pressure switch.
