[. . . ] - Re-install the primary air regulation bracket at the distance “H” as shown in table page 9, see also “Primary air regulation”. CONTROL OF PRIMARY AIR FLOW - Primary air can be considered correctly adjusted if no flame lift is ensured when the burner is cold and the injector lights when the burner is hot. - The distance “H” (see figure “Primary air regulation”) recommended for primary air adjustment is stated in table page 9 in the “Technical data”. REPLACEMENT OF INJECTORS FOR PILOT BURNER - The injector of the pilot burner can be reached by removing the lower front panel. - The pilot burner is in the front of the combustion chamber. - Unloose the screw and replace the injector with an appropriate one. COMMISSIONING AND TESTING - Once all the connections have been made, the appliance and the overall installation must be checked following the directions given in this manual. - Check in particular: - that the protective film has been removed from the external surfaces; - that connections have been made in accordance with the requirements and directions indicated in this manual; - that all safety requirements in current standards, statutory regulations and directives have been met; - that the water and gas connections are leak-free; - that the electrical connection has been performed according to standards. - Now the appliance can be ignited following the instructions for use and controlling the following points: - progressive ignition of the burner; - even flames; - flame security: check these points at both minimum and maximum output. - Check that the flue gas exhaust is not clogged and that they are expelled without any hindrance. - The test report must be completed in full and submitted to the customer who should then sign in acceptance. With effect from this moment, the appliance is covered by the manufacturer’s warranty. MINIMUM OUTPUT ADJUSTMENT - Once the appliance has been switched on, set the cock knob on the minimum position. - Remove the cock knob that will reveal a small hole on the panel of the appliance. - Turn the minimum adjustment screw on the cock with a screwdriver through the hole on the panel. Warning!: Measure the minimum output pressure directly at the output pressure connection on the injector tube (see figure “Measuring gas pressure”) - Set the output pressure of the gas cock according to the figures stated in table page 9 - Minimum output setting). - After setting, seal the adjustment screw!Warning!: After each conversion, it is necessary to check tightness and operation! 032- 03 - Gas kettles 12 MAINTENANCE OF THE APPLIANCE Warning!: All maintenance operations shall only be performed by a technically qualified service centre!- To ensure correct and safe operation, the appliance must be inspected and serviced at least once a year only. Maintenance includes also to control the components and tear of pipes, feeding pipes etc. . It is advisable to replace worn components during maintenance operations to avoid the need for other maintenance calls and unexpected failures. - It is also advisable to apply for a maintenance contract with the customer. POSSIBLE FAILURES AND THEIR ELIMINATION Warning!: Only technically qualified service centres can perform the operations described below!Warning!: Before resetting the safety thermostat, it is always necessary to eliminate the problem causing its activation (only for models with indirect heating)! Problem and possible cause Access to components and operation The content of the vat does not heat up: - the safety thermostat has been activated. The pilot burner is on but the main burners do not light up: - loss of pressure in gas supply; - clogged injectors on main burners. The pilot burner does not light up: - clogged injectors on pilot burner; - faulty ignition plug; - check the cable of the ignition plug. The pilot burner does not remain lighted: - faulty thermocouple; - partially clogged injector on pilot burner; faulty cock magnet. [. . . ] For the same reason avoid contact with materials containing iron. - Do not use sandpaper or abrasive paper for cleaning; in special cases use a powder pumice stone. - In case of particularly resistant dirt, it is advisable to use abrasive sponges (e. g. - It is advisable to clean the appliance only once it has cooled down. SPECIAL PROCEDURES IN CASE OF FAILURES - If the appliance should not work properly during use, turn it off immediately and close or cut off all supplies (gas and water). [. . . ]
