He should observe the Regulations and Codes of Practice governing such installation of gas appliances. Note: It is recommended that the gas connection to the appliance is installed with a flexible connecting tube made to BS5386. Notes: – Flexible hoses can be used where the sited ambient temperature of the hose does not exceed 70°C. These hoses must be manufactured in accordance with BS669 part 1 and be of the correct construction for the type of gas being used. – Gas hoses designed for natural gas MUST NOT be used for supplying LPG gas (LPG gas hoses can be identified by a either a red band or stripe on the rubber outer coating of the hose). The hose should not be crushed or trapped or be in contact with sharp or abrasive edges. 15 15 Gas connection Cat: II 2H3+ The fitting (fig. 17) is made up of: – 1 nut “A” – 1 elbow fitting “C” – gasket “F” Connection to the Gas Supply – Be careful when flexible pipes are used that they do not come into contact with moving parts. – To maintain the thickness of 3 cm, the hob is fitted with a channel to contain the connection pipe. – The gas inlet union can be turned in the direction required after the elbow fitting “C” and nut “A” connection (figure 17) has been slackened (fig. 18). – Never put it in the horizontal or vertical position. – Never attempt to turn the elbow “C” without having first slackened off the relative lock nut “A”. – The gasket “F” (fig. 17) guarantees the seal of the gas connection. It is recommended that it be replaced whenever it shows even the slightest deformation or imperfection. – Using a suitable leak detection fluid solution (e.g. Rocol) check each gas connection one at a time by brushing the solution over the connection. The presence of bubbles will indicate a leak. If there is a leak, tighten the fitting and then recheck for leaks. IMPORTANT! Do not use a naked flame to test for leaks. 1/2" G conical (ISO 7-1) male 1/2" G cylindrical (ISO 228-1) male 1/2" G cylindricalemale1/2" G cylindrical (ISO 228-1) female C F A If installation is to be carried out using a flexible connector (to BS669), then the following points must be adhered to: Note: The gas installation pipes and the final connection to the appliance connecting pipe shall be sufficient size to maintain the heat output of the appliance as specified under installation. 1. The appliance flexible connector should not be subject to undue forces, either in normal use whilst being connected or disconnected. 2. The appliance flexible connector should not be subject to excessive heat by direct exposure to flue products or by contact with hot surfaces. 3. The socket into which the plug of the appliance flexible connector fits should be permanently attached to a firmly fixed gas installation pipe and positioned such that the hose hangs freely downwards. 4. The appliance flexible connector should be positioned such that it will not suffer mechanical damage; eg abrasion from the surrounding kitchen furniture which may be moved in use, such as a door or drawer, or by being trapped by a stability device. 5. The plug-in connector should be accessible for disconnection after moving the appliance.

The burners are conceived in such a way so as not to require the adjustment of the primary air.

The adjustment is performed with the burner lit, as follows: – Turn the knob to the minimum position. – Remove the tap knob. – Turn the screw “A” to the correct setting with a screwdriver (fig. 21). For LPG, tighten the adjustment screw completely. A Fig. 21 Lubrication of the Gas Taps The operations must be executed by a qualified technician. IMPORTANT: All intervention regarding installation maintenance and conversion of the appliance must be fulfilled with original factory parts. The manufacturer declines any liability resulting from the non-compliance of this obligation. 18 18 Incorrect installation may be dangerous and the manufacturer can not be held responsible. Warning! This appliance must be earthed The manufacturer declines all ...
