2-4.Working principle
The gas flows out of the valve nozzle at a certain flow rate under a certain pressure and enter the
burner. The gas sucks the primary air by its own energy. In the burner, the gas is mixed with the
primary air and then flows out through the fire cover hole.
Ignition needle discharge generates high-frequency pulse electric spark which ignites gas
mixture at the hole, so that it reacts with the surrounding secondary air to burn, forming a blue
flame;

Note: Please refer to relevant installation instructions for specific use occasions.
3-2.Standard installation process
Check the barcode of the product outside the packing box and confirm
whether the model and temperament of the machine are the same as the model
purchased by the user.
Before opening the box, check whether the packing box is in
good condition, communicate with the user in case of any damage and
check the cause of damage when receiving the goods. Before the
packing can be opened, the packing must be confirmed to be good.
Place the cooking appliance on a stable countertop or on the
ground to ensure stable product placement;
Cut the packing tape on the packing box with the blade and open
the packing. Note that the blade does not extend too far into the inside
of the packing box (it is recommended that the sealing tape doesn’t to
exceed 1mm). Do not use excessive force to prevent damage to the
internal product.
After removing the box, remove the foam cover with both hands
and then remove the whole machine on the water platform for the next
operation;
All packaging materials are environmentally friendly and
recyclable. Please dispose of these packaging materials in an
environmentally friendly manner to maintain a good environment;
Do not allow children to play with plastic film and packaging
boxes, which may cause choking accidents;

3-3.Test machine after installation
Ignition tester Open the main air source, press the knob to discharge. At the same time,
turn the knob counterclockwise by approximately 90 degrees so that the gas
enters the interior of the cooker and burns to form a flame at the fire lid;
●
After the flame is ignited, it is required to be delivered to each fire hole
within 4 seconds;
Observe if the flame can be properly ignited and if there is a sudden
flame and there is a phenomenon of ignition noise (detonation). If a
deflagration occurs, check whether the gas pressure meets the rated
pressure of the cooker. If the pressure is stable or there is a large
difference from the rated pressure, contact the gas company for gas
circuit perfection (Note: Rated pressure of liquefied gas: 2800Pa; Rated
pressure of natural gas: 2000Pa;);
Keep pressing the knob for 3-5 seconds and let go. The flame should
continue to burn normally without any flameout.
Turn the switch to the minimum flame state for combustion. The
flame should be able to burn normally without flameout.
Repeat 10 ignition operations. It should be ensured that there are 8 or
more ignitions and 2 consecutive failures cannot be made.
Flame regulation performance tester
When the cooker is in normal combustion, turn the knob to adjust the firepower
and observe the change of flame at different angles;
Turn large fire to small fire and small fire to large fire as an adjustment cycle. Repeat
the above cycle for 10 times. The flame change should be normal and no flameout can
occur.
If there is a related combustion failure, the details of the treatment are described later
troubleshooting instructions.

With the consent of the user, the V-bottom p and pan will be
placed on the holder rack. The base pan has to be stable.
After the pot is in the natural state on the holder rack, pour
about 500g of water into it and no water flows out.
Then place the pan in a horizontal position and the pan
should not slide automatically and cause the water to flow
out.
Note: For V-bottom pot, if there is a phenomenon that
interferes with the fire cover when it is placed directly on the
holder rack, take out the small rack and place it on the holder
rack before verifying base pan.
3-4.Product operation Precautions for users:
When using, do not allow the product to be exposed
to strong winds (for example, if the strong wind from
Use precautions
outside the window directly blows the flame), this will
affect the normal working conditions of the combustion
or even work.
Remind the user to stay cautious for overheating of frying
pan when using vegetable oil or animal fat oil for food cooking.
When cooking food with such grease, do not leave the food in
the pan and leave it alone;
During the training, in case of burning due to the high oil
temperature, immediately cover the fire with a large area of
metal such as iron cover to cut off the air for combustion, and
then close the indoor gas valve. Don’t use water to extinguish
the fire to prevent accidents;
Close the gas valve on the indoor duct after using the
cooker, or before going out or going to bed;
When you need to remove the pan for a short time, switch
the burner to a small fire position. In this way, the risk of burns
can be reduced even if other operations are performed near the
cooker, and gas can be saved and pollution can be reduced.

3-5. Cleaning and maintenance
After installation, the installer should remind the user to pay attention to the following matters in cleaning and
maintenance:
Cooktop cleaning and maintenance
Fire cover cleaning and maintenance
Recommended maintenance
Before cleaning the gas cooker, the indoor gas valve must be
cut off and the gas cooker has cooled. Do not disassemble the
safety devices and airtight parts of gas cookers during the
cleaning process;
Do not use acidic materials (lemonade, vinegar, etc.) to scrub
enamel surfaces (eg, holder rack, etc.);
Please use soft gauze and soapy water (or stainless steel
special cleaning agent) to clean and maintain the cooker board;
Do not clean the board with a granular detergent (scrub
powder) or steel wool. This can cause scratches on the surface
of the cooker.
For long-term use, there will be oil pollution inside the fire
cover. As shown in the figure on the left, the fire cover can be
disassembled without any tools, and the oil inside the fire cover
can be cleaned easily and simply;
When dismantling or installing the fire cover, avoid hard
objects from colliding with the ignition needle to prevent the
needle from being damaged and affecting the use of the cooker.
After cleaning and maintenance, place the fire cover in place
(for details, see 3-4 "Inspection of parts in place");
In the use process, if you find that the flame is uneven or there is
no flame in the individual fire holes, after the fire cover cools, remove
the fire cover in time and clean the dirt and carbon deposit in the fire
hole with iron brush and steel needle. Do not wipe the inorganic
water-resistant coating on the burner surface with a hard object. This
will cause damage to the black surface that cannot be repaired;
Wipe the discharge end of the ignition needle in time to
prevent the dirt from attaching to the surface and affecting the
ignition performance.
