AIR ADJUSTMENT
In the case of the PM/M type burners, the air gate is operated by an electrical servo control. The positions of
the gate are determined by cams, with reference to graduation markings shown on the disc.
The cams are operated by means of the key provided: they feature a clutch and are self-locking.
By pushing button B, the air gate drive system is disengaged, freeing this for manual movements.
