Instructions for the Installer
4.Gas connection
If the appliance is installed above an over, the gas hose must be passed around the back of the oven to prevent overheating.
The connection to the gas mains may be made using a copper pipe or a continuous-wall steel hose in accordance with the relevant regulations. To simplify connection, the horizontal position of the fitting A on the back of the appliance is adjustable. Undo the hexagonal nut B, turn the fitting A into the required position and re-tighten the hexagonal nut B (it has a rubber gasket to ensure it provides an effective seal). When installation is complete, check for any leaks with a soapy solution, never with a naked light. The hob is tested with G20 (2H) natural gas at the pressure of 20 mbar. For use with other types of gas, see point "5. ADAPTING TO DIFFERENT TYPES OF GAS". The gas intake connection has an external ½" gas thread (ISO 228-1).
Connection with copper pipe: The connection to the gas supply mains must be made so that no stresses or strains of any kind are applied to the appliance. The connection can be made using the adapter unit D with two conical elements, always fitting the gasket C supplied.
Connection with steel hose: use only continuous-wall stainless steel hoses compliant with the relevant regulations, and always fit the gasket C supplied between the fitting A and the hose E.
When connecting with a hose, ensure that the total length of the pipeline is not more than 1.5 metres; also ensure that the hoses do not touch moving parts and are not crushed.
