ELECTRODES ADJUSTMENT
The position of the electrodes should always be checked after any work on the combustion
head. They should be positioned according to the indications supplied in the figure below.
IMPORTANT: the ignition electrodes and the control electrode must never touch the
diffuser, the draught tube or other metallic parts. If this were to happen they would no
longer work, thus impairing operation of the burner itself.
