40.2 Configuring the air pressure switch
dreizler
®
gas power burners are equipped with air pressure switches as standard, which are set to the pres-
sure range of the burner as differential pressure on the blower.

NOTICE:
These air pressure switches must be set to 80% of min. differential pressure (in accordance with DIN/EN
676 'Gas power burners').
NOTICE:
An unalterable trouble shut-off occurs if the air pressure value falls below the preset value.

The burner must then be manually unlocked by pressing the release button on the automatic gas control
box.
The air pressure switch must be set by a technician during commissioning and must be checked during
each maintenance. The standard value is the air pressure value during pre-purge phase, and not the air
pressure value during burner operation.


Measuring the min. differential pressure by way of a differential pressure manometer during pre-purging

Configuring the air pressure switch to 80% of min. value.
