Flame adjustment
Oven burners
The burner is correctly adjusted when the flame
is stable, silent and goes out without any noise.
• When the flames are too short, the nozzle is
whistling or the flames have the tendency to
detach from the burner, it means that there is
too much air in the valve. If there is too much
air there is a risk that the flames will
extinguish.

there is not enough air in the valves. These
flames discolour the bottom of pans.
