To adjust the flame properly, refer to the following 
five-stage flame power indication chart and function 
descriptions. Select your flame as desired.

To ignite the burner: when the knob is turned to OFF 
(0 degree), press it down and turn it to the ignition 
position (30-40 degrees counterclockwise). The flame 
of the internal ring should ignite; while the flame of the 
external ring is not yet ignited. Press the knob down, 
turn it and hold it down for 3-5 seconds before 
releasing. If the flame goes out after the release, 
return the knob to the vertical OFF (0 degree) position 
and repeat the above ignition operations.

Special instructions:

- The ignition position at - 40 degrees is to prevent any 

sudden gas release at the moment of ignition, which 
may briefly cause an excessively high flame, 
especially with artificial gas.

When the burner head is ignited, first release the knob, 
and then turn the knob counterclockwise to the 
maximum flame position (90 degrees). The flame will 
spread from the internal gas ring to the external ring 
rapidly.

When the knob is turned counterclockwise from the 
maximum flame position (90 degrees) to the medium 
flame position (170 degrees), the small flame of the 
internal ring will remain unchanged, but the flame of 
the external ring will gradually be extinguished.

When the knob is turned counterclockwise from the 
medium flame position (170 degrees) to the minimum 
flame position (230 degrees), the small flame of the 
internal ring will gradually be reduced to the lowest 
setting.

Special instructions

- The innovative 230-degree dial wide range of flame 

power adjustment ensures the flame power can be 
adjusted conveniently and accurately to suit your 
needs.

After you are finished using the gas hob, please turn 
the knob clockwise to OFF (0 degree), the flame will 
then go out. For your safety, please close the gas 
valve on the indoor pipeline after using the gas hob.

Cleaning and 
maintaining your hob

Before cleaning the gas hob, you must switch off the indoor gas 
valve, and wait until the gas hob has cooled. When cleaning, 
do not dismantle the safety device or sealed parts of the hob.

Clean the faceplate of the gas hob
Use soft gauze and soap suds (or special cleansers) to clean 
and maintain the hob faceplate. If you want to remove the 
fingerprints left on the stainless steel surface, you should use a 
3M cleanser. It is best not to use a chloride-based cleanser to 
clean the glass.

Do not use a granular cleanser (decontamination powder) or 
steel wool to clean the faceplate. These may cause scratches 
on the surface of the hob.

Clean the pan supports of the gas hob
Clean the pan supports  with a soft, gauze cloth and a solution 
of cleanser and hot water.

Do not use an acid based cleanser (lemonade, vinegar etc.) to 
wash the enamel surfaces. 

Attention: When dismantling the cap parts prior to cleaning and 
re-assembling them after cleaning, take care when touching the 
ignition needle as it is made of ceramic material which can be 
easily damaged.

Clean the burners of the gas hob (recommended frequency: 
cleaning at least once a month)
Use a soft brush to remove the dirt on the surface of the burner 
base, ignition electrodes and thermal couples. (Do not touch 
ignition electrodes during cleaning)

Do not use a granular cleanser (decontamination powder), 
sharp objects, steel wool or a knife etc, to remove the dirt left 
on the burner. These objects and cleaners can damage the 
safety devices of the gas hob, or may wear down the 
component surface, thus shortening the life-span of the product.

Clean the caps of the gas hob (recommended frequency: 
cleaning at least once a month)
When you are using the hob, you may find the flame is not 
uniform or some burner openings have no flame. In such cases, 
after the hob has cooled, you should take off the cap and use 
an iron slice and steel needle to remove the dirt and carbon 
blocking the burner openings.

Do not wash the cap directly with water (as the bubbles may 
temporarily block the fire holes). Do not use a hard object to 
wipe the burner surface with an inorganic water-based and 
temperature-resistant coating, which could result in permanent 
damage to the black surface.

After cleaning is complete, please re-install the supports, 
burner heads and caps in accordance with the illustration (see 
page 11). Any permanent scratches on the top sheet surface 
caused by incorrect installation are not covered by the warranty.

Once the surfaces of the products are cleaned, please ensure 
they are put back correctly, otherwise the electronic ignition 
devices may not work normally. The heads and caps should be 
dried completely prior to putting them back. 

Pan supports must be dried completely prior to putting them 
back in.
