Adjusting the combustion head
In order to adjust the combustion head, proceed as follows:
1 remove the bunrer cover;
2 set the combustion head by means of a screwdriver, working on the screw VRT: rotate counterclockwise to move the combustion
head forward, or rotate clockwise to move it backwards;
3 replace the burner cover.
The burner is adjusted in the factory with the combustion head in the position that refers to the "MAX" output. The maximum output set-
ting refers to the “fully-ahead” position of the combustion head, as far as standard models (Fig. 10), and to “fully-backward” position for
low NOx burners (Fig. 11). As for “fully-ahead” position, it means that the head is placed inside the boiler, “fully-backward” position
means that the head is towards the operator. To remove the combsution head, please refer to par. “Removing and cleaning the combu-
stion head” on page 22. As far as the reduced output operation, progressively move the combusiton head towards the “MIN” position,
rotating clockwise the VRT screw (see next figure). The ID index shows how much the combustion head moved.
