Adjusting the minimum level
Fig. 6 To adjust the minimum level of the burners, proceed as follows: 1. Light the burner. 2. Turn the knob on the minimum position. 3. Remove the knob. 4. With a thin screwdriver, adjust the by-pass screw (see Fig. 7). If changing from natural gas to LPG, completely tighten clockwise the screw, until a small regular flame is obtained. 5. Finally check the flame does not go out when quickly turning the knob from the maximum position to the minimum position. This procedure can easily be carried out, anyhow the hob has been positioned or built in the working top.
