The hob has been inspected for G20 (2H) natural gas at a pressure of 20 mbar. To allow the unit to work with this type of gas, perform the same operations described in paragraph “5.2 Regulation for LPG”, but choose the nozzles and regulate the primary air for natural gas, as shown in the following table and in paragraph "5.4 Regulation of primary air”. After the regulations have been carried out, restore the seals with sealing wax or equivalent material.
