IMPORTANT INFORMATION

Conversion of the 6” W.C. pres- sure regulator to 10” W.C.

Remove the hexagonal lid from the upper part of the regulator with an adjustable wrench. Remove the plastic button on the lid and turn it, pressing it firmly into place so that the letters "LP", instead of "NAT" can be clearly read on the button. Replace the lid and button set on the upper part of the regulator, properly sealing it. Make sure that the spring is in place. Do not over-tighten.

NOTE: The arrow on the rear part of the regulator should point in the direction of the gas flow on the cooktop. Fig. 9.

After performing the gas transformation, always ensure that the flame of the burners is correct, so that when changing from the maximum to the minimum setting it does not go out, or cause backflashing.

5 - It is important to ensure the proper placement of all seals in order to prevent any short circuits in case of spillage on the cooktop.

6 - Replace the control knobs on the taps. Never remove the tap shaft. In case of fault, change the whole tap.
