How to use the gas hob

Gas burners
The gas flow to the burner can be regulated by turning the corresponding control knob to one of the following positions . (see Fig.1)

OFF (close valve)

High (maximum aperture or flow)

Low (minimum aperture or flow)

The size of flame depends on the position of the related burner control knob.

The burner should be set at large flame during the initial phase of the cooking to allow quick heating of the cooking contents. After quick heating, turn the control knob to small flame for slow warming of food or maintaining heating conditions. Other flame adjustment can be achieved by positioning the indicator between the large flame and small flame. Never adjust the flame size between the large flame and OFF position

Igniting the burners
The appliance is equipped with automatic ignition system and flame failure safety device. To ignite the burner, carry out the following steps:

a. Press and turn the corresponding control knob anti-clockwise to the large flame position. The gas burner will be ignited.
b. At this position, hold down the control knob for 5 seconds to allow the flame to heat up the thermocouple.
c. Then, release the knob and the flame shall be remained lighted up.
d. Turn the control knob to achieve the flame as desired.
e. If the flame can’t be lighted, turn the control knob clockwise to the off position.
Then repeat step a to c.
f. After cooking is completed, turn the control knob clockwise to the off position.

Battery Ignition
The automatic ignition system is powered by a 1.5 V battery. If the automatic ignition does not work, check the battery compartment under the gas hob to ensure that the battery is positioned correctly. Replace the battery if necessary (see Fig.9 in page 9).

Selection of burners and diameters of pan
On the control panel, near every knob, there is a diagram to indicate the burner controlled by the corresponding knob. Select the burner in accordance to the diameter of the pan used and the heat input.

The recommended burners for the flat bottom pan diameters are as follow:

It is important that the diameter of the pan is suitable to the heat input of the burner. During usage, adjustment of the control knob is required to ensure that the flame does not extend out from the bottom of the pan. (see Fig.2)

Correct use of Ultra-rapid burner
To use the wok, you need to position the wok directly onto the center of the pan support. Recommended wok top’s open diameter shall not exceed 36 cm. For gas hob models without Auxiliary, while using the flat bottomed pan with diameter less than 12 cm, you need to position the mini trivet (Fig.3) provided onto the pan support. After lighting the burner, adjust the control knob so that the flame length do not extend out from the bottom of the pan so as to prevent overheating of the pan handle (see Fig.2 ).

Flame failure safety device
This gas hob is equipped with flame failure safety device. In the event, the flame is accidently extinguished, the supply of gas to that burner will be shut off. Before re-lighting the burner, turn off the burner control knob and do not attempt to re-ignite the burner for at least one minute.

Cleaning the Wok Burner
The burner cup must always be kept clean. While cleaning the burners, remove the burner caps and use a cotton bud, toothbrush or some other items to clean out any incrustations or dirt from area marked as “H” in Fig.4. This procedure is necessary to ensure correct the functioning of the burner. Clean the burner caps using needle or toothbrush to remove the dirt and carbon, blocking the burner holes. (Fig.5)

After cleaning the burners and the caps they must be well dried and put back correctly. It is very important to check that the burner cups F, burner cap A and cap B has been correctly positioned (Fig.6)-failure to do so can cause serious problem

As shown by the arrow, the “M” positioning of the inner cap cover must be aligned with the “m” clamping position of the burner cup, and the “N” positioning of the inner cap cover must be aligned with the “n” clamping position of the burner cup (as shown on the left side of Fig.6). The burner correctly positioned must rotate.

How to place the pan support
In order to prevent the pan support from rotating, there is a special positioning support. During installation, make sure that the special positioning support is placed exactly on the groove of the spill tray (Fig. 7).

Check that the ignition electrode “S” (Fig.8) is always clean to ensure trouble-free sparking. Check that the probe or thermocouple “T” (Fig.8) is always clean to ensure correct operation of the safety valves. Both the ignition electrode and the thermocouple must be very carefully cleaned.

Note: Regular use may cause discoloring around the burners due to high temperature of the flame.
