SETTING OF THE GAS BURNERS

When the jets have been changed it is necessary to set the correct air gap by keeping to the setting “X” as shown in the table “ gas consumption” fig 7. Warning the value of ‘ X ‘ setting varies in relation to the size of gas burner and type of gas chosen. A good flame must be of medium length (fig.8B), excessive air will cause the flame to be short and with sharp colour (fig.8C): in this case it is necessary to extend out the tube for the air setting from the burner body, if there is insufficient air the flame will appear weak and long (fig. 8A): in this case push the tube of the air setting back into the burner body. To adjust the air setting tube loosen the retaining screw. Once the air is correctly set secure the screw over the tube ( fig. 7).
For dimensions «X» see table of gas consumption

REGULATING THE MINIMUM FLAME

After lighting the burners, turn the control knob to the minimum setting and then remove the knob (this can easily be removed by apply a gentle pressure). Using a small «Terminal» type screwdriver the regulating screw can be adjusted as in Fig. 9. Turning the screw clockwise reduces the gas flow, whilst turning it anticlockwise increases the flow – Use this adjustment to obtain a flame of approximately 3 to 4 mm in length and then replace the control knob. When the gas supply available is LPG (Bottle gas)- the screw to set the idle flame must be turned (clockwise) to the end stop.
Screws regulating (for differend models)When you have carried out the new gas regulation, replace the old gas rating plate on your appliance with one (supplied with hob) suitable for the type of gas for which it has been regulated.

USE OF HOB USER INSTRUCTIONS

This appliance must only be used for the purpose for which it is intended, domestic cooking, and any other use will be considered improper and could therefore be dangerous. The Manufacturer will not be responsible for any damage or loss resulting from improper use.

USING THE GAS BURNER

To ignite the burners, place a lighted taper close to the burner, press in and turn the control knob anti-clockwise.
If the burners have not been used for a couple of days, wait for a few seconds before lighting the burner, this will allow any air present in the pipes to escape.
For appliances fitted with electronic ignition carry out the following:

• push in and turn the knob anticlockwise to the ★ symbol.
• ignite the burner by pressing the sparker button.

For hobs fitted with automatic ignition simply push in and turn the knob to the ★ symbol.
The ignition system will continue to generate sparks as long as the gas tap is being pressed.
If the burner is not ignited within 5 seconds, turn the knob to the 0 position and repeat the operation.
For models fitted with a safety tap (which cuts-off the flow of gas if the flame is accidentally extinguished) the burners are ignited ad described above, but care must be taken to keep the knob pressed in for 5 or 6 seconds after the flame is ignited.
ATTENTION: Prior to switching on the gas hob ensure that the burners and burner caps are correctly placed within their position.
GENERAL ADVICE
For the best results, the flat-bottomed pans size should match the gas burner size as follows. See fig. pag. 1-2.

For smaller containers the gas burner should be regulated so that the flame does not overlap the base of the pan. Vessels with concave or convex base should not be used.
WARNING: If a burner is accidentally extinguehed, turn the knob to the off position and do not attempt to re-ignite if for at least 1 minute.
If over the years the gas taps become stiff to turn it is necessary to lubricate them.
Such operation must be carried out only by qualified Service Engineers.

MAINTENANCE AND CLEANING

Before cleaning the Hob, ensure the appliance has cooled down. Remove the plug from the socket or (if connected directly) switch off the electricity supply.
When cleaning the enamelled, varnished or chrome sections, use warm soapy water or a non caustic detergent. For stainless steel use an appropriate cleaning solution. Hotplates should only be cleaned with a cotton cloth coated with vaseline or seed oil. Never use abrasives, corrosive detergents, bleaching agents or acids. Avoid any acid or alkaline substances (lemon, juice, vinegar etc.) on the enamelled, varnisched or stainless steel sections.The burners can be cleaned with soapy water. To restore their original shine, use a household stainless steel cleaner. After cleaning, dry the burners and replace. It is important the Burners are replaced correctly.

AFTERCARE

Before calling out a Service Engineer please check the following:

• that the plug is correctly inserted and fused;
• that the gas supply is not faulty.
