manual movement possible.
Cam I maximum air opening
Cam II air closure, while still
Cam III air opening, 1st stage ignition
Cam IV consent for the opening of 2nd stage valve
(at least 6o more than cam III)

TECHNICAL NOTE REGARDING "ECO DEN" LOW-SULPHUR COMBUSTION OIL
ECO DEN fuel has low sulphur contents (≤ 0.5% in weight) and can therefore be considered an environmentally-friendly
fuel, with emissions of sulphur dioxide (SO
12-15° E at 50° C does not normally consent direct suction from the tank by means of the burner pump. In such cases it is
advisable to provide a "ring" supply circuit for the burner with an auxiliary pump which will make fuel circulate and supply
