ELECTRODES ADJUSTMENT
An ignition electrode and a control electrode have been fit-
ted. 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.
The position of the electrodes should always be checked
after any work on the combustion head.
