Securing the burner to the boiler
Before fixing the burner to the boiler, check from the opening of the blast tube that the probe and the electrode are correctly positioned,
as in Fig. 13.
If, in the previous check, the position of the probe or electrode was not correct, remove the screw 1)(Fig. 14), extract the inner part
2)(Fig. 14) of the head, and adjust them.
Do not rotate the probe: leave it as in Fig. 13 If it is located too close to the ignition electrode, the control box amplifier may be damaged.
