Performing the conversion
1. Take off pan bracket, burner cover and burner crown without using tools
(fig. 1, 2).
2. Replace all main jets (fig. 3). To do this you will need a 7 mm socket spanner.
3. Screw the air regulators onto the main jets as tight as they will go
(fig. 4).
4. Remove all knobs and rubber seals on the control panel (fig. 5).
5. Adjust all low setting jet (fig. 5).
6. Use a water proof pen to write on the conversion label and stick it on the
underside of the hob near the gas tap (fig. 6).
7. As a final check, turn the knob of each burner quickly (in about 1 second)
from the maximum setting to the minimum setting. When you do this, the
flame must not go out. If this should happen, an adjustment of the low
setting jet is required.
8. After the conversion has been carried out all jets are to be re-sealed.
