4. How to Take Care of Your Gas Stove

Before cleaning or maintenance, disconnect the appliance from the power source. To extend the life of the gas hob, it is essential to clean it thoroughly. Removable burner parts should be washed with soap and warm water. The automatic ignition pin should be cleaned carefully to ensure normal function. Stainless steel surfaces can stain from hard water or corrosive detergents; rinse thoroughly with water and dry. Clean spills immediately. Use a cleaning scraper (not supplied) for food or grease residues. Clean the cooking surface when warm with a suitable cleaning product, paper towels, and a damp cloth. Remove melted sugar or plastic items immediately. Avoid abrasive sponges or aggressive cleaning agents.

When cleaning the grill/pan holder, it is recommended to do so while it is still hot. For stainless steel, use neutral soaps with warm water, then dry and polish. If gas valves become stuck, they may require cleaning and greasing by an authorized technician.

Practical advice on burner use:

• Use appropriate cooking utensils for each burner size.
• Always use flat-bottomed utensils and keep lids on.
• Turn the knob to "Low" when contents boil.

5. Installation

These instructions are for qualified installers. Important: Unplug the electrical connection before performing any maintenance. The gas hob must be installed and used only in rooms with permanent ventilation.

Ventilation Requirements:

Diagram Description: Two diagrams illustrate ventilation options. The first shows ventilation holes in a wall or fireplace setup, labeled "In a fireplace or fireplace branched (exclusively for kitchen appliances)" and "Directly outside". The second shows "Examples of ventilation holes for combustion air" and "Enlarge the ventilation slot between the window and the floor".

The room must be equipped with a ventilation system (hood or electric fan) to expel smoke and combustion gases. Adequate combustion air is required (minimum 2 m³/h per kW). Air supply should be via a duct with at least 100 cm² cross-section. Gas plates without safety devices require ventilation operating in two volumes (minimum 200 cm²). Intensive operation may require intensified ventilation.

LPG Tanks: Liquefied petroleum gases are heavier than air and settle downwards. Rooms with LPG tanks require outward ventilation. Do not store LPG tanks below ground level. Keep only the operating tank in the room, away from heat sources.

Installation Precautions:

• The hob can be located in a kitchen, dining room, or living room, but not in a bathroom or shower.
• Furniture near the unit, if taller than work tables, must be placed at least 110 mm away.
• Cabinets near the hood must be at least 420 mm high.

Diagram Description: Two diagrams show required clearances when fitting the hob. One is without a cooker hood above, showing 700mm vertical clearance from the top of the hob to any overhead unit, and 400mm horizontal clearance from the sides. The other is with a cooker hood above, showing 600mm vertical clearance from the top of the hob to the hood, and 400mm horizontal clearance from the sides. A cross-section diagram shows the hob thickness (40mm) and the minimum distance from the worktop to the underside of an overhead cabinet (700mm).

The hob must be installed directly under a cabinet, which must be at least 700 mm from the worktop. Fixing accessories (hooks, screws) are provided for table tops measuring 20 to 40 mm thick.

Diagram Description: Three diagrams show hook positions for different hob thicknesses (H=20mm top, H=30mm top, H=40mm top). A further diagram illustrates installation in a built-in oven without forced ventilation, showing air inlets and outlets for cabinet ventilation. Another diagram shows a cabinet space requirement of 45 x 560 mm from the back.

If not installed in a built-in oven, a wooden panel for insulation should be inserted at least 20 mm from the plate's bottom.

Gas Connection:

The gas hob must be connected by a registered installer. Install an approved gas tap to isolate the supply. Connect to the gas network or liquid gas according to regulations. Ensure compatibility with the gas type. Use pressure regulators for liquid gas tanks. For safety and longevity, ensure gas pressure conforms to specifications.

Connection Types:

• Non-flexible tube (copper or steel): Ensure no tension points. Use an adjustable "L" shaped connector and gasket. The supply connector is threaded 1/2 gas cylinder.
• Flexible steel tube: Use pipes and sealing gaskets meeting current standards. Maximum length is 2000 mm. Ensure the tube does not touch moving parts or get crushed.

Seal Check: Use soapy water to test connections for leaks; never use flames.

Electric Connection

The hob is equipped with a three-pole power supply cable for alternating current. The ground wire is identifiable by its greenish-yellow color. If installed with a built-in electric oven, the electrical connections for the hob and oven must be independent.

Electrical Connection for Gas Hob: Connect the power cable with a standard plug or directly to the mains. A one-pole switch should be placed between the board and the mains. Position the power supply cable to avoid reaching temperatures greater than 50°C above ambient temperature.

Before Connection: Ensure the fuse and electrical system can withstand the load, the power supply has an efficient ground connection, and the plug or switch is accessible.

Wiring Color Code:

• Green and Yellow: Earth
• Blue: Neutral
• Brown: Live

Connect wires according to terminal markings (E/Green/Yellow, L/Red, N/Black).

How to Convert a Gas Source

Adjustment of the reduced valve flow

Valve adjustment

Valve adjustment should be done with the control knob set at Burner ON saving flame position. Remove the knob, and adjust the flame with a tiny screwdriver (see fig.7 below).

Figure 7: Valve Adjustment

Diagram Description: Two images illustrate valve adjustment. The first shows a gas valve with a screwdriver inserted into the adjustment screw. The second shows a close-up of the valve adjustment screw.

To check the adjusted flame: heat the burner at full open position for 10 minutes. Then turn the knob into the saving setting. The flame should not extinguish nor move towards the nozzle. If it extinguishes or moves, readjust the valves.

Flame Selection

When the burners are adjusted correctly, the flame should be light blue, and the inner flame should be clear. The size of the flame depends on the position of the control knob.

Figure 8: Flame Selection Options

Diagram Description: Three circular diagrams represent control knob positions. The first shows a knob in a position labeled "-Burner ON, large flame". The second shows a knob in a position labeled "-Burner ON, small flame (saving mode)". The third shows a knob in a position labeled "-Burner OFF".

The burner should be set at a large flame during the initial phase of cooking to boil food quickly, then turned to the saving flame position to maintain cooking. It is possible to adjust the flame size steplessly. Adjusting the flame between the Burner OFF and Burner ON large flame positions is prohibited.

Energy conservation is maximized when the hob is used correctly with appropriate cookware and flame settings. Up to 60% of energy can be conserved with proper pots and correct flame size selection. Keeping burners clean is crucial for efficient and energy-saving operation.

Troubleshooting

If the gas plate does not work suddenly or properly, verify the following before calling customer service:

• Ensure there are no interruptions in gas and electricity supplies, and that gas valves are open.
• Burner cannot ignite or flame is not uniform: Check that gas holes are not clogged, all moving parts are fixed correctly, and there is no air flow around the cooking surface.
• Flame does not stay lit with thermocouple: Ensure the knob is pressed completely, held long enough to activate the thermocouple, and that gas holes in the thermocouple area are not obstructed.
• Flame goes out when knob is turned to "Low" setting: Check that gas holes are not clogged, there is no air flow around the cooking surface, and the minimum setting is correct.
• Kitchen grates (battery) are not stable: Verify that the bottom of cookware is flat, the grates are centered correctly on the burner, and support grilles are not inverted.

If the gas plate still does not work properly after these checks, contact the Customer Service Center and provide details about the problem and the model number. Never use unauthorized technicians or non-manufacturer spare parts.
