WARNING
As soon as a liquid starts boiling, turn down the flame so that it will barely keep the liquid simmering. If the control knobs become difficult to turn, please contact your local service center.
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 flash back on the upper aluminum seats and cause the upper aluminum seats to melt and deform, see below figures for correctly placing the burner caps

Re-ignition:
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.
