Frequently Asked Questions - CM17451 CONSTRUCTA

How to light a burner?

Press the knob of the selected burner and turn it to the left to the ignition position. Hold it pressed for a few seconds until the flame ignites, then release and adjust to the desired position.

What to do if the ignition does not work?

Check that the spark plugs and burners are clean and dry. Clean the space between the spark plug and the burner with a small brush. Make sure the burner caps are correctly placed.

Why is the flame of a burner not uniform?

The burner parts may be incorrectly assembled or the gas outlet grooves are dirty. Reassemble the parts correctly and clean the grooves with a non-metallic brush.

What to do if a gas odor spreads in the kitchen?

Check that no gas tap is open. If the odor persists, shut off the gas and electrical supply, ventilate the room and contact the after-sales service immediately. A leak at the cylinder connection is possible.

How to clean the burners and grids?

Let the appliance cool down. Disassemble the burners and grids, soak them in soapy water, then brush them with a non-metallic brush. Rinse and dry completely before putting them back in place.

Why does an audible signal sound and all burners turn off?

This indicates overheating of the hob. Set all controls to the off position (●). The signal will stop. Wait about 30 minutes for the appliance to cool down before using it again. If the signal persists, call technical service.

Can I use a steam cleaner to clean the hob?

No, the use of a steam cleaner is prohibited because it presents a risk of electrocution and may damage the appliance. Use only a sponge and soapy water after cooling.

What to do if a burner goes out during cooking and does not relight?

The safety system has shut off the gas supply. Turn the burner control to the off position (●). The audible signal stops. You can then relight the burner normally. If the extinction is due to a liquid spill, clean the burner before relighting.

What cookware diameters are recommended for each burner?

Triple flame burner: 22 cm minimum; Rapid: 22-26 cm; Semi-rapid: 12-20 cm; Auxiliary: 10-12 cm. Use flat, thick-bottomed cookware and always put a lid on to save energy.

Where to find the reference for additional grids?

The grid for the triple flame burner (diameter >26 cm) has the reference 363300/484138. The coffee maker grid for the auxiliary burner (diameter <10 cm) has the reference 184200. Contact Constructa after-sales service to order them.

Your new hob:

Gas burners

Fig. 1.

Each control knob indicates which burner it controls. (Fig. 1.)

To light a burner, push in the knob for the burner you wish to use and turn it in an anti-clockwise direction to the lighting position. Hold the knob at the maximum position for a few seconds until the burner ignites and then release and set the knob to the desired setting. If the burner does not light at the first attempt, repeat the operation.

If the spark plugs are dirty, then a fault may occur in the ignition system. Keep them completely clean. Clean the spark plugs using a small brush, remembering that the plugs must not receive any kind of violent impact.

If the burner goes out (e.g. a draught) when in use, the appliance will switch the hotplate on again automatically. If this ignition is unsuccessful (e.g. as a result of boiled-over liquid on the burner), the flow of gas to this burner is interrupted and an acoustic signal is emitted. Turn the control knob to and check whether the cause can be rectified using the table on page 11.

Every hotplate features a safety pilot!

This means that if the flame ever goes out (e.g. is extinguished by boiled-over liquid), the flow of gas is interrupted.

The safety system will indicate any anomalies in its working through acoustic signals (see "Home troubleshooting" section).

The appliance switches off automatically after 6 hours of operation. Turn all the control knobs to the position and then you can turn the appliance on again.

To turn the burners off, turn the control knob in a clockwise direction to the setting.

Your modern functional hob is equipped with progressive valves which permit you to find the perfect flame setting between maximum and minimum.

Depending on the model that you have purchased, your hob may come with a triple-flame burner, the perfect system for cooking paellas, using woks, etc.

Gas appliances create both heat and humidity in the room they are used in. Make sure that your kitchen is properly ventilated: keep natural ventilation outlets open or install a mechanical ventilation system (extractor fan). When using your appliance for a prolonged period of time, it may be necessary to provide additional ventilation e.g. by opening a window (without creating a draught) or turning up the setting on your mechanical ventilation system.

Overheating protection

The hob is equipped with overheating protection to protect the electronics. This switches all the burners off in the event of overheating and the "power on/off" indicators in all the burners and the main switch flash.

Turn all control knobs to the position. Wait until the appliance has cooled down sufficiently. Now you can switch on the appliance as usual.

Recommended receptacle diameters (cm.)

Depending on model:

BURNER MINIMUMORECEPTACLE MAXIMUMORECEPTACLE
Triple flame: 22 cm
Rapid:	22 cm 26 cm
Semi-rapid:	12 cm 20 cm
Auxiliary: 10 cm 12 cm

Additional pan support:

Fig. 2.

Depending on the model that you have purchased, your hob may come equipped with an additional pan support. This pan support is essential when using the triple-flame burner for receptacles with diameters of more than 26 cm, griddles, terracotta casseroles and all kinds of concave receptacles (woks, etc.) (Fig. 2).

If you do not have a pan support, then these are available from your Service Centre, code 363300/484138.

Coffee pot support: Depending on the model that you have purchased, your hob may come equipped with an additional coffee pot support. This pan support is only for use on the auxiliary burner for receptacles with diameters of less than 10cm . If you do not have a pan support, then these are available from your Service Centre, code 184200.

The manufacturer cannot be held responsible for the non-use or misuse of these additional pan support.

Warnings concerning cooking:

DON'Ts

DOs

Do not use small receptacles on large burners. The flame should not touch the sides of receptacles.

Always use suitably sized receptacles on each burner. This helps avoid excessive gas consumption and prevents receptacles from getting tarnished.

Do not cook without lids or with lids only partially covering receptacles. You are wasting energy.

Always use lids.

Do not use receptacles with uneven bases. They lengthen cooking times and increase energy consumption.

Only use thick-,flat-based saucepans, frying pans and casseroles.

Do not place receptacles on burners off centre. They could tip over.

Do not use wide-based receptacles on the burners nearest to the controls.

When centred on the burner, they could touch the controls or raise the temperature in the area. This may damage the hob.

Always place receptacles in th middle of burne

Do not place receptacles directly on top of burners.

Always place receptacle on the pans support.

Do not use excessive weights or strike the hob with heavy objects.

Handle receptacles on the hob with care.

Cleaning and maintenance:

DON'TS DOs

Never use abrasive products, sharp objects, steel scouring pads, knives, etc., to remove stubborn food remains from the hob surface, pans support, burners or electric plates.

If your hob comes with a glass or aluminium panel, do not use knives, scrapers or similar utensils to clean the join with the metal.

Do not use steam appliances to clean the hob with. They could damage it.

Once the appliance is cold, clean it with a sponge and soapy water. Remove all excess liquid immediately. This will help you avoid unnecessary effort later. The burners and pans support must be cleaned regularly to keep them clean. This is done by submerging them in soapy water and scrubbing them with a non-metal brush to keep the holes and slits free from obstruction so they can give a perfect flame.

Do not allow acid products (vinegar, lemon juice, etc.) to come into contact with the hob.

Try to prevent salt from coming into contact with the surface of the electric plate.

Dry the burner covers whenever wet or damp. Remove all excess liquid immediately. This will help you avoid unnecessary effort later.

After cleaning and drying the burners, make sure that the covers are properly in position on the flame diffuser.

If the coating on the electric plates has worn off through use, smear them with a few drops of oil or one of the maintenance products available on the market.

The high temperatures suffered by the cover on the triple-flame burner ring and the stainless steel parts on your hob (plate rings, grease trays, area around burners, etc) may become discoloured over time. This is NORMAL. Clean them after use with a product suitable for stainless steel.

After washing the pans support, dry them thoroughly before cooking with them again. The presence of droplets of water or dampness at the beginning of the cooking process may damage the enamel surface.

If the pans support on your hob are supplied with rubber feet, be careful when cleaning as they may come off, leaving the pan support unprotected and scratching the hob surface.

The cleaning product suitable for stainless steel must not be used in the area surrounding the control knobs. The indications (serigraphy) may get deleted.
