Adjusting the combustion head

E165A, E205A

The burner is factory-adjusted with the combustion head in the "MAX" position, accordingly to the maximum power. To operate the bur-
ner at a lower power, progressively shift back the combustion head, towards the "MIN" position, screwing the screw

VRT

. The ID index

shows how much the combustion head moved.

CAUTION:

perform these adjustments once the burner is turned off and cooled.

Attention! if it is necessary to change the head position, repeat the air and fuel adjustments described above.
