• Press the ignition device and hold the knob till the burner is ignited
• Before releasing knob, ensure a flame is established.
• If the burner fails to ignite, put it into the off position and try again.

If in case of a power failure or failure of the ignition, a match or lighting devise can be used. Care must be taken when using this method. The device shall not be operated for more than 15s. If after 15s the burner has not lit, stop operating the device and open the compartment door and/ or wait at least 1 min before attempting a further ignition of the burner. In the event of the burner flames being accidentally extinguished, turn off the burner control and do not attempt to re-ignite the burner for at least 1 min.

CAUTION: Accessible parts may be hot when the grill is in use. Young children should be kept away. As shown in Figure 7, place the burner onto the burner base one by one and stuck, rotate left and right to check if the burners are in place, the burner is placed correctly when it cannot be rotated. Finally center placed the burner cap on the burner.
If you cannot light the flame even after several attempts, check the “cap” and “crown” (see diagram – figure 7). Make sure they are in the correct position. To put the flame out, turn the knob in the clockwise direction until it stops (it should be on the “OFF” setting).

WARNING
Users could not use the cooking vessels on the hotplate that overlap its edges.

WARNING
All burner caps can’t be dislocated installation, otherwise it will lead to flashback on the upper aluminium seats and cause the upper aluminium seats to melt and deform, see below figures for correctly placing the burner caps

Reignition:
If the flame is out for certain reasons, the safety device will cut off the gas power automatically. Turn the switch to ” OFF ” position, then ignite again, you should wait for 30 seconds when you do that. Due to the air in the tong, there may be unsmooth ignition, revolve the switch to ” OFF ” position and ignite again.

Care and Maintenance
Before any maintenance or cleaning can be carried out, you must DISCONNECT the gas cooktop from the electricity supply. The gas cooktop is best cleaned while it is still warm, as spillage can be removed more easily than if it is left to cool.

Control Panel

• Sign OFF = gas valve is shut off
• Sign HI =largest flame
• Sign LO=smallest flame
• Sign = electric discharge for ignition

The Burners
The burner caps and crowns can be removed for cleaning. Wash the burner caps and crowns using hot soapy water, and remove marks with a mild paste cleaner. A well moistened soap impregnated steel wool pad can be used with caution, if the marks are particularly difficult to remove. After cleaning, be sure to wipe dry with a soft cloth.

Ignition electrode
The electric ignition is obtained through a ceramic “electrode” and a metal electrode. Keep these components very clean, to avoid lighting difficulties, and check that the burner crown holes are not obstructed.

Thermocouple
The thermocouple is very crucial for cutting gas supply in case of flame out during cooking, be sure to keep them in very clean condition. Maintenance instructions suggesting (We suggest to clean it every six months.):

1. Keeping appliance area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.
2. Not obstructing the flow of combustion and ventilation air.
3. Visually checking pilot(s) and burner flames, with pictorial representation.
   • Remove the utensil supports.
   • Light burners.
   • Turn knobs from MAX to MIN, Check the flame status, the flame in the MIN position should be smaller than in the MAX position, as the figure is shown below.
   • Always check flame before each use, see TROUBLESHOOTING if any abnormal status is found.
