made as outlined below. Repeat the operation for the other cam points.
Adjustment the intermediate gas flow rates (see figure, detail 3): - using a suitable Allen wrench, change the position of
the cam guide blade; if you screw it down, the flow rate is reduced; if you unscrew it, the flow rate increases.
SETTING THE FIRING HEAD
The firing head position adjustment is made in order to obtain the best combustion efficiency. When used with mini-

The control of the detector current shall be carried out by plugging a microampe-
rometer with full scale at 1000 µA (D.C.) in series with the UV-cell. If the detec-
tor current is too low verify the connection between phase and neutral of the bur-
ner and the grounding of the burner itself. Minimum required detector current is
200 µA.
