3.1 Settings
Head and air damper adjustment
The adjustment of the head depends on the flow-rate of the
burner. The head is adjusted by rotating the adjustment screws
"B" clockwise or anticlockwise until the notch on rod "A" is n
line with the reference.
This modifies the position of the baffle in respect to the drau-
ght tube, and as a consequence the flow of air.
To limit the amount of dispersion from the stack when
the boiler is off, the burner is fitted with a gravity-
closing air damper that closes automatically when the
burner stops.

"1".
2° stage:
to remove the cap "3" and swivel the screw "4" with a screwdriver till the desired value.
Reposition the cap.
