for model BT 250 DSG (steel fixing flange)
for model BT 300 - 350 DSG
REMARKS
When tightening the flange, it is important to do it evenly so that the inner faces are parallel between them. Since
the locking system is highly efficient, do not tighten the nuts too much.
During this operation (tightening of the flange locking nuts) keep the body of the burner lifted so that the combustion
head is kept in a horizontal position.
