Town gas a) Auxiliary burner and semi-rapid burners: after fitting the nozzles ( lett. "B"), screw the provided grid filter "A" (� 10) on them; b) Rapid and Ultra-rapid burner burners: screw the provided grid filter assembly "C" (� 16) on it. 4. Reassemble the parts, following the same procedure backwards. 5. Replace the rating label (placed near the gas supply pipe) with the relevant one for the new type of gas supply.

Adjusting the minimum level
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. When converting from LPG to town gas unscrew about one turn by-pass pin, until a regular small flame is reached. 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.
