Gas connection
Choose fixed connections or use a flexible pipe in stainless steel in compliance with the regulation in force. If using flexible metallic pipes, be careful they do not come in contact with mobile parts or they are not squeezed. Use the same attention when the hob is combinated with an oven. IMPORTANT - To ensure a correct operation, a saving of energy and the long-life of the appliance, the voltage pressure of the appliance must correspond to the recommended values. The adjustable connection is fixed to the comprehensive ramp by means of a threaded nut GJ 1/2". Interpose the sealing between the components as shown in fig. 4. Screw the parts without forcing, adjust the connection in the required direction and tighten everything.
Connection using flexible non metal pipes
When the connection can be easily inspected in its full extent, there is the chance to use a flexible pipe according to the rules in force. The flexible pipe must be tightly fixed using clamps according to the rules in force. Natural gas : use the pipe fitting «D» (Fig. 4). LPG : use the rubber pipe holder «E». Always insert the gasket «B». Then proceed with the gas connection. The flexible pipe should be made ready for use in such a way that: - nowhere it can reach overtemperature, other than room temperature, higher than 30°C; if the flexible pipe, to reach the cock, must run behind the range, it must be installed as shown in Fig. 4; - it is no longer than 1500 mm; - it shows no throttles; - it is not subject to traction or torsion; - it doesn't get in touch with cutting edges or corners; - it can be easily inspected in order to check its condition. The control of preservation of the flexible pipe consists in checking that: - it doesn't show cracks, cuts, marks of burnings both on the end parts and on its full extent; - the material is not hardened, but shows its normal elasticity; - the fastening clamps are not rusted; - expiry term is not due. If one or more abnormalities are seen, do not repair the pipe, but replace it.

Important
Once installation is complete, check the perfect seal of every pipe fitting, using a soapy solution, never a flame
