The Ariston hob is a cooking appliance designed for domestic use, featuring both gas burners and, in some models, electric hotplates. Its primary function is to provide a versatile cooking surface for various culinary needs. The gas burners offer adjustable flame settings from minimum to maximum, allowing for precise heat control, while the electric hotplates, where present, provide six different heat settings. The appliance is designed for built-in installation and requires proper ventilation and gas/electrical connections to ensure safe and efficient operation. Safety features, such as a gas safety device that stops gas flow if the flame extinguishes, are integrated into certain models.
Each gas burner is controlled by a dedicated knob, clearly indicating its corresponding burner. To light a burner, users must press down and turn the knob anti-clockwise to the maximum setting. For models with a safety device, the knob needs to be held down for approximately 2-3 seconds to allow the device to heat up and keep the flame lit. Some models feature an ignition button (marked with a star symbol) or an ignition switch integrated into the control knob for automatic lighting. If the flame accidentally extinguishes, the control knob should be turned off, and users must wait at least 1 minute before attempting to relight it. To switch off a burner, turn the knob clockwise until it reaches the "off" position.
For efficient cooking, it is recommended to use cookware appropriate for each burner size, ensuring the flames do not extend beyond the bottom of the pan. Cookware should always have a flat base and a cover. Once the contents of a pan reach boiling point, the flame should be reduced to the minimum setting. The manual provides a table with recommended cookware diameters for each burner type (Fast, Reduced Fast, Semi Fast, Auxiliary, Triple Crown).
Electric hotplates are controlled by selector knobs that can be turned clockwise or anti-clockwise to six different positions, ranging from "Off" (0) to "High" (6). The "on" light illuminates when the selector knob is in any position other than "off." Before initial use, the hotplates should be heated at maximum temperature for approximately 4 minutes without any pans, allowing their protective coating to harden. To avoid heat loss and damage, use pans with a flat base, with a diameter no less than that of the hotplate itself. The manual provides a guide for different cooking tasks corresponding to each heat setting, such as cooking vegetables (setting 1), boiling potatoes (setting 2), simmering large quantities of food (setting 3), roasting (settings 4-5), and browning or bringing to a boil quickly (setting 6).
The appliance is a class 3 built-in device and requires regular air exchange for efficient operation. It is designed for domestic use and should not be installed outdoors or exposed to rain and storms. Users should avoid touching the appliance with bare or wet feet/hands. Only adults should use the appliance for cooking according to the instructions. Power supply cables of other electrical appliances should not come into contact with hot parts of the hob. Ventilation openings must never be covered. Knobs should always be in the "off" position when the appliance is not in use. When unplugging, pull the plug from the mains socket, not the cable. Pan handles should be turned towards the center of the hob to prevent accidental burns. The glass cover (if present) should not be closed when burners or hotplates are hot. Electric hotplates should not be left on without a pan. Unstable or deformed pans should not be used.
Always disconnect the appliance from the electricity supply before performing any maintenance or cleaning work.
Abrasive or corrosive detergents, stain removers, anti-rust products, powder detergents, or abrasive sponges should not be used, as they can scratch the surface. Steam cleaners or pressure cleaners are also prohibited. Typically, the hob can be cleaned with a damp sponge and dried with absorbent kitchen roll. Removable parts of the burners should be washed frequently with warm water and soap to remove burnt-on substances. For hobs with automatic lighting, the terminal part of the electronic instant lighting devices should be cleaned frequently, and gas outlet holes checked for blockages. Electric hotplates should be cleaned with a damp cloth and lubricated with a small amount of oil while still warm. Stainless steel surfaces can be marked by hard water or aggressive phosphorus-containing detergents. After cleaning, rinse and dry any remaining water drops.
Over time, gas taps may become stiff or difficult to turn. If this occurs, the tap must be replaced by a qualified technician authorized by the manufacturer.
The manual includes a troubleshooting section to address common issues such as burners not lighting, flames dying, or unstable cookware. Solutions often involve checking for clogged gas holes, ensuring correct assembly of burner parts, verifying proper knob operation, and confirming adequate ventilation. If problems persist, users are advised to contact a Customer Service Centre, providing the appliance model and serial number. Unauthorized technicians or non-original replacement parts should never be used.
