22 Ignition transformer
22.1 Ignition transformer ZE 30 / 7.5 (single pole)
22.1.1 Description
The ignition transformer is equipped with a unilaterally earthed high-voltage winding. It functions with single
pole ignition. That means that the ignition electrode ignites against mass. The ignition electrode can me
moved and adjusted on the connection piece of the burner head. It functions as mass against the burner
head.
22.1.2 Technical data
NOTICE:
The best spark gap distance is between 2 and 3mm.
22.1.3 Single-pole ignition
