Adjusting the electrodes
Important Note: Check the ignition and detection electrodes after removing/adjusting the combustion head.
ATTENTION: avoid the ignition and detection electrodes to contact metallic
parts (blast tube, head, etc.), otherwise the boiler’s operation would be com-
promised. Check the electrodes position after any intervention on the com-
bustion head.
ATTENTION: avoid the ignition electrodes to contact metallic parts (blast tube, head, etc.), otherwise the boiler’s operation
would be compromised. Check the electrodes position after any intervention on the combustion head.
ATTENTION: avoid the ignition and detection electrodes to contact metallic parts (blast tube, head, etc.), otherwise the boi-
ler’s operation would be compromised. Check the electrodes position after any intervention on the combustion head.
