This changes the position of the baffle in relation to the nozzle and accordingly the air passage.

To adjust the air delivery, turn the screw "

tighten the nut " D ".
To limit dispersion to the flue with the boiler turned off, the burner is equipped with a gravity-
operated air lock that shuts automatically when the burner stops.
