22The connection of the cooker to the gas bottle or to themains should only be carried out after the unit has beenregulated for use with the type of gas which will besupplied. Be sure that you are going to connect the unitto the same kind of gas written on the plate. For safeoperation, minimum consumption and longer duration ofthe unit, make sure that the pressure of supply is equalto the value indicated in the Technical Data section.IMPORTANTOnce installation is complete, check the perfectseal of every pipe fitting, using a soapy solution,never a flame.Rigid connectionFor a greater safety, it is advisable to make a rigidconnection to the gas installation. The coupling to theunit is of Gc 1/2 type. If the connection pipe is in metal,an insulated adaptor must be interposed between thecoupling and the tube.Connection with flexible pipeUse a flexible gas pipe, according to the characteristicsindicated by the existing regulations. The pipe should bewell fitted and fixed by means of a clamp. To reach thesupply connection, the pipe should be passed behindthe cooker as shown in the diagram. We bring to yourattention some of the main existing regulations. Theflexible tube must not be reach in any point a temperatu-re higher than 90°C, it should not be no longer than 1,5m.It should not be subjected to any kind of traction or torsionand it should not be allowed to be excessively bent. Aneasy access should be allowed to periodically check itscondition.Should any leaking occur, do not repair il but insteadreplace it.ServiceTo guarantee good working order and safety, theregulation taps should be periodically greased. Servicecan be made in the following way: Remove the knobsand the control panel after having removed the fixingscrews. Unscrew the 2 screws placed at the sides of theburner valve shaft. Unwind the cone and clean it withcare; then spread over the valve a thin layer of grease notsoluble by hydrocarbon. Pay attention to the fact thattoo much grease can obstruct the passage of gas. To fitagain the burner valve in the normal position, you shouldreverse the procedure outlined above.Gas connectionFO 0163Electric cableFlexible pipe
