Open the valve on the gas supply. Using a soap and water solution check each gas connection one at the time, by brushing the solution over the connection. Presence of bubbles will indicate a leak. Tighten the fitting and recheck for leaks. If it is not possible to correct the leak, replace fitting. Under no circumstances use matches or flame for checking leaks. It is essential that the gasket and the pressure test point stopper are properly installed to avoid gas leakage Fig.5B Inches mm A 1 9/16” 45 B 8 .” 210 C 8 .” 215 D 1/8” 22 Fig.5A 7.To checking inlet pressure at the appliance operate as follow: a) Disconnect electric power before pressure checking be carried out. b) Take off one of the gas burner cap and the relative flame spreader in order to get access to the burner injector. c) Put in position the pressure detector directly on the burner injector afterward open the relative burner knob at maximum position keeping it pressed, then measure the outlet pressure from the burner injector. d) Once the pressure checking has been carried out, replace the burner cap and flame spreader in the correct and original position and re-connect electric power to the appliance. 8. Turn on appliance control cock and light each burner. Check for a clear blue flame without yellow tipping. If burners show any abnormalities check that they are located properly and in line with the injector nipple. 5 9. Sometimes the burners will not ignite immediately and seem to ‘blow’ slightly when they do ignite. This usually due to air in the gas lines, which will clear itself within seconds. 10. If after following the instructions given, satisfactory performance cannot be obtained, contact the local gas authority for advice and assistance. Electrical connection The connection of the hobs to mains is effected via the flex and the three pin plug located underneath the hotplate. The appliance operate at a main voltage of 120V a.c., frequency 60Hz. Electric power absorption is about 1W. WARNING: Electrical Grounding Instructions: This appliance is equipped with a (three-prong) grounding plug for your protection against shock hazard and should be plugged directly into a properly grounded receptable. Do not cut or remove the grounding prong from this plug. Wiring diagrams Wiring diagram description 1. Cable terminal 2. Spark generator 3. Ignition spark L. Black N. White T.

ATTENTION: An exhaust fan may be used with the appliance; in each case it shall be installed in conformity with the national standards in force. ATTENTION: Exhaust hood operation may affect other vented appliances; in each case it shall be installed in conformity with the national standards in force. Conversion to different types of gas Before carrying out any maintenance work, disconnect the appliance from the gas and electric supply. For Natural Gas fit regulator assembly described in Fig. 5A. For LP Gas fit assembly described in fig. 5A. - CHANGING THE NOZZLES FOR USE WITH OTHER TYPES OF GAS: To change the nozzles of the burners use the following procedure: Lift up the burners and unscrew the nozzles ( Fig. 6) using an adjustable spanner of 7 mm and change the nozzles with those designed for the new gas supply according to the information given in TABLE A shown below. fig.6 fig.7 TABLE A: Adapting to different types of gas LP (E) By-pass size [1/100mm] 29 37 58 61 73 CAUTION: save the orifices removed from the appliance for future use 7 Regulation of burners Regulation of the "MINIMUM" on the burners To regulate the minimum on the burners carry out the following procedure indicated below: 1) Turn on the burner and put the knob onto position MINIMUM ( small flame ). 2) Remove the knob ( Fig. 7) of the tap which is set for standard pressure. The knob is found on the bar of the tap itself. 3) Beside the tap bar on the work top, insert a small slotted screwdriver into the hole on the vale rod (Fig. 7) and turn the choke screw to the right or left until the flame of the burner is regulated in the most suitable way to MINIMUM. 4) Make sure that that the flame does not go out when changing the position quickly from MAXIMUM to the MINIMUM position. ATTENTION: The regulation described above can be carried out only with burners using natural gas, while with burners using propane gas the screw must be fully screwed in, in a clockwise direction. Adaptation of the pressure regulator for use with different type of gas The pressure regulator supplied with the appliance is a convertible type pressure re...
