Flame adjustment
Oven burner
The burner is correctly adjusted when the flame is
stable, silent and goes out without any noise.
When the flames are too short, the injector is
whistling or the flames have the tendency to
detach from the burner, it means that there is
too much air in the burner. If there is too much
air there is a risk that the flames will extinguish.
But, if the flames are too long, soft, lighting,
there is not enough air in the burner. These
flames discolour the bottom of pans.

Move the air adjuster A forward or backward
until achieving the right mixture (see table no.

Tighten the securing screw M.
