Changing the gas inlet:
For some countries, the gas inlet type can be different for NG/LPG gases. In such a case, remove the
current connection components and nuts (if any) and connect the new gas supply accordingly. In all
conditions, all components used in gas connections should be approved by local and/or
international authorities. In all gas connections, refer to the "Assembly of gas supply and leakage
check" clause explained before.
