How to Keep Your Gas hob in Shape

Before cleaning or performing maintenance on your gas hob, disconnect it from the electrical power supply (including battery power). To extend the lifespan of the gas hob, it is indispensable that it is cleaned carefully, thoroughly, and usually, please keep in mind to the following:

• The enameled parts and the glass top must be washed with warm water without using abrasive powders or corrosive substances that could ruin them.
• The removable parts of the burners should be washed usually with warm water and soap, make sure to remove caked-on substances.
• Automatic igniter pin, the end must be cleaned carefully and usually, make sure ignition keeps working normally.
• Stainless steel top plate and other steel parts can be stained if kept in touch with high-concentration calcareous water or corrosive detergents (containing phosphorus). To extend the lifespan, we advise these parts to be rinsed thoroughly with water and dried by blowing, It is a good idea to clean up any spills too.
•  After the glass hob working, the surface must be cleaned with a damp cloth to remove dust or food residues. The Glass surface should be cleaned regularly with warm water and non-corrosive detergent.

First, remove all food residues or greases with a cleaning scraper, e.g.
Cleaning scraper (not supplied) (Fig. 1 ). While the cooking surface is warm, clean it with a suitable cleaning product and paper towels, then rub it with a damp cloth and dry the surface. Such as aluminum foil, plastic items, objects made of synthetic material, sugar or foods with a high sugar content that have been melted onto the surface, it must be removed immediately. While the cooking surface is still hot, clean it with a scraper and a transparent protective film which prevent more dirt. This also protects the surface from damage caused by food with a high sugar content. Do not use abrasive sponges or cleaning products, this holds true for chemically aggressive cleaners, like oven sprays and stain removers (Fig.2);

• Cleaning the grill/pan support, it is recommended to clean it while it is still hot. To move the grill away from the hob and put it in the sink, remove the food residues or grease first, after the grill has cooled, rinse it with water.

Greasing the Gas Valves
Over time, the gas valves may be sticked, and it is difficult to turn on/off. For this case, should clean the inside of the valve and grease it. Kind reminder: This procedure must be performed by a technician authorized by the manufacturer.

Practical Advice

Practical Advice on Using the Burners
For best performance, follow these general guidelines:

• Use the appropriate cookware for each burner (see table) to prevent the flame from reaching the side of the pot or pan.
• Always use cookware with a flat bottom and keep the lid on.
• When the contents come to a boil, turn the knob to “Low”.

To identify the type of burner, refer to the designs in the section entitled, “Burner and Nozzle Specifications”.

Is there a Problem?

If you find the gas hob cannot work suddenly or cannot work properly. Before calling customer service for assistance, let us check what we can do.
First, check and confirm there are no interruptions to the gas and electrical supplies, particularly, if the gas valves keep turn on.
The burner cannot be lighted, or the flame is not uniform around the burner.
Check to make sure that:

• The gas holes on the burner are not clogged.
• All the movable parts of burners are fixed correctly.
• There is no airflow around the cooking surface.

The flame does not keep lighting to the burner with the thermocouple.
Check to make sure that:

• You press the knob all the way.
• You keep pressing the knob for enough time to activate the thermocouple.
• The gas holes are not clogged in the area corresponding to the thermocouple.

The flame goes out while turning the knob to the “Low” setting.
Check to make sure that:

• The gas holes are not clogged.
• There is no airflow around the cooking surface.
• The minimum has been adjusted correctly (see the section entitled “Minimum Regulation”).

The cookware is not stable.
Check to make sure that:

• The bottom of the cookware is perfectly flat.
• The cookware is centered correctly on the burner
• The support grids have not been inverted.

After checking all of these, the gas hob still does not work properly, please call the Customer Service Center, and inform them of:

• Tile type of problem.
• The gas hob model number (Model. … ) is indicated on the packing carton.
• Never call the technicians who are not authorized by your supplier and refuse to use spare parts that are not from the manufacturer.

Installation Instructions for built-in

The following instructions are directed at the qualified installer, so the installation and maintenance procedures may be followed in the most professional and expert manner.
Important: Unplug the electrical connection before performing any maintenance or regular upkeep work.
Positioning for gas hob
Important: this unit may be installed and used only in permanently ventilated rooms. The following requirements must be observed:

• The room must be fitted with a ventilation system that ventilates smoke and gases from combustion to the outside of rooms. This must be done by hood or electric ventilator
• The room must be allowed for the influx of the air which is for proper combustion. The airflow for combustion purposes must not less than 2 m3/h per kW of installed capacity. The air supply will be affected by influx from the outside through a duct, its inner cross-section is at least 1 00cm2 and must not be blocked accidentally. The gas hob without safety devices, to prevent flame go out accidentally, must have a ventilation working on twice the volume. For example, a minimum of 200 cm2 (Fig. 3). Otherwise, the room can be vented indirectly through adjacent rooms which is fitted with ventilation ducts to the outside. Although the adjacent rooms are not shared areas, bedrooms, but fire risk is hidden (Fig. 4).
• Intensive and prolonged working of the gas hob that needs to intensify ventilation, e.g., opening windows or increasing the power of the air intake system (if present).
• Liquefied petroleum gases are heavier than air, so settle it downward. Rooms in which LPG tanks are installed must be fitted with ventilation to the outside to avoid of gas leakage.

Therefore, LPG tanks that are empty or partially full, must not be installed or stored in rooms or spaces below ground level (cellars etc.). It is a good idea to keep only the tank, which is working currently in the room, and make sure that it is not closed to heating source (ovens, fireplaces, stoves, etc.).
Installation of built-in gas hob
The gas hobs are designed with a protection degree against excessive heating, the appliance can be installed next to cabinets, and the height should not exceed the hob. For a correct installation, the following precautions must be followed:

• The hob may be in a kitchen, a diner or bed/ sitting room, but not in a bathroom or shower room.

• The furniture standing near to the unit, it is higher than the working boards, it must be placed at least 110mm distance to the edge of the board.

• The cabinets should be positioned near to the hood at a height of 420 mm at least (Fig. 5).

• Hob should be installed directly under a cupboard, the latter should be at least 700mm from the worktop, as shown in Fig.6.

• Fixing fittings (hooks, screws) are provided to place the hob on the work top, measuring 20 to 40 mm in thickness (see Fig. 6).

N.B: Use the hooks contained in the “accessories bag.”

• In the event the gas hob is not installed on a built-in oven, a wooden panel must be inserted for insulation. This panel must be placed at least 20 mm distance from the bottom of the hob.
• important: When installing the hob on a built-in oven, the oven should be placed on two wooden strips; in the case of a joining cabinet surface, remember to leave a space of 45 x 560 mm at least from the back side.

When installing hob on a built-in oven without forced ventilation, ensure that have air inlets and outlets to ventilate the interior of the cabinet adequately.

Gas connection for gas hob

• The gas hob should be connected to the gas supply by a registered installer. During installation, it is essential to fit an approved gas tap to isolate the supply from the hob for the convenience of any subsequent removal or servicing. Connect the hob to the gas
• mains or liquid gas, it must be carried out according to the prescribed regulation in force, and only after it is ascertained that it is adaptable to the type of gas to be used. If not, follow the instructions indicated in the paragraph headed “Adaptation to different
• gas types”. In the case of connection to liquid gas by tank, use pressure regulators that conform to the regulation in force.
• Important: For safety, for the correct regulation of gas use and long life of the hob, ensure that the gas pressure conforms to the indications given in Table 1 “Burners and Nozzle Specifications”.

Connection to non-flexible tube

• (Copper or steel)
• Connection to the gas source must be done in such a way as to not create any stress points at any part of the gas hob.
• The hob is fitted with an adjustable “L” shape connector and a gasket to the gas supply.
• The connector should be dismounted, and the gasket must be replaced.
• The feeding connector of the gas to the hob is threaded 1/2 gas cylinder.

Connection to the flexible steel tube

• The gas feed connector to the hob is threaded, 1/2″ connector for round gas pipe. Only use pipes and sealing gaskets that conform to the standards currently in force. The maximum length of the flexible pipes must not exceed 2000 mm. Once the connection
• has been made, ensure that the flexible metal tube does not touch any moving parts and not be crushed.

Check the Seal

• Once the hob is installed, make sure all the connections are properly sealed, use soapy water to test, and never use flame.

Electrical Connection
The hob is fitted with a tripolar electrical supply cord which are designed to be used alternating current. According to the indications on the rating plate located under the hob. The earthing wire can be identified by its yellow-green colour.

• In the case of installation over a built-in electric oven, the electrical connections for the hob and oven should be independent, not only for safe purposes but also be convenient to remove them in the future.

Electrical Connection for Gas hob

• Fit the supply cord with a standard plug for the demand rate indicated on the rating plate or connect it directly to the electrical mains. In the latter case, a single pole switch must be placed between the hob and the mains, with a minimum opening between the
• contacts of 3 mm in compliance with current safety codes (the earthing wire must not be interrupted by the switch). The power supply cord must be positioned so that it does not reach a temperature more than S0°C than room temperature at any point.

Before actual connection make sure that :

• The fuse and electrical system can withstand the load required by the hob.
• The electrical supply system is equipped with an efficient earth hook-up according to the norms and
• regulations prescribed by law.
• The plug or switch is easily accessible.

Important: the wires in the main lead are colored in accordance with the following code:

• Green – Earth
• White – Neutral
• Black – Live

As the colors of the wires in the main lead may not correspond with the colored markings identifying the terminals in your plug, proceed as follows: Connect the Green & Yellow wire to the terminal marked ” or colored Green or Green & Yellow

• Connect the Brown wire to the terminal marked *L” or colored Red.
• Connect the Blue wire to the terminal marked “N” or colored Black.

Valve adjustment

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

To check the adjusted flame: heat the bumper at a fully open position for 10 minutes. Then tum the knob into the saving setting. The flame should not extinguish nor move to the nozzle, If it extinguishes or moves to the nozzle, readjust the valves.
Flame selection
As the bumpers are adjusted correctly, the name should be light blue, and the inner flame should be clear. The size of the flame depends on the position of the related control knob

See fig.8 for various operating options (flame size selection); the burner should be set at a large flame during the intial phase of cooking, it makes food boil quickly. Then should tum knob to the saving flame position to maintain the cooking. It is possible to adjust the flame size stepless.

It is prohibited to adjust the flame between the Burner OFF and Burner ON large flame positions.
High quantity of energy can be conserved if the hob is used correctly, parameters are designed correctly, and appropriate cookware is used. The energy conservation be as follows:

• Up to 60% are conserved when proper pots are used,
• Up to 60% are conserved when the unit is operated correctly, and the suitable flame size is chosen.

It is a prerequisite for the efficient and energy-saving operation of hob that the burners are always kept clean (the
flame slots and nozzles). Adapting to different types of gas
