Common knowledge on the use of hot pot and gas stoves:

1. How to judge whether the gas stove is leaking? When the user suspects that the gas stove is leaking, please check according to the following steps:

l Please prepare an appropriate amount of soapy water (preferably thicker) for leak detection.

l Open the ventilation valve to make the air source unobstructed.

l Check whether there is air leakage at the connection of the pressure reducing valve (only applicable to liquefied gas): dip a small amount of soapy water and drop it on the initial connection between the pressure reducing valve and the liquefied gas tank. Observe whether there are bubbles. If so, If bubbles occur, you need to consult the user to replace the pressure reducing valve.

l Check whether there is air leakage at the interface connecting the hose: perform the same test as above.

l If the above method still cannot eliminate the air leakage, you need to come to the house for inspection.

2. Where is the damper of the gas stove? What does it do? Hold up the gas stove with your hands. There are two iron pieces with handles at the connection between the burner and the nozzle. One of them adjusts the low flame and the other adjusts the high flame. They are both tightly attached to the burner through springs and gently stir. The handle can adjust the size of the air inlet, thereby changing the state of the flame. When the combustion conditions are not ideal, such as yellow fire, black fire, flame is too large or too small, or combustion noise, backfire and other phenomena occur, a more ideal combustion condition can be achieved by adjusting the air inlet volume at the damper< /p>

3. Why is the gas stove not a blue flame? Please observe, if the main part of the flame is blue, and the yellow and red flames only float at the outer flame ends, this is not a product problem, but caused by impurities in the temperament, and the blue flame in the main part completely ensures full combustion Safety and thermal efficiency, does not affect the performance of gas stoves.

4. Why does the gas stove appear prosperous?

l Gas reason: When the combustion gas contains too much water or too many impurities, the color of the flame will appear red.

l Cause of dust: When there is dust in the house or when the amount of moisture and oil and gas in the air increases when cooking, red fires are also likely to occur.

l Damper reason: This situation may also occur when the damper adjustment position is not good. In this case, you only need to adjust the damper.

l Reasons for the pot holder: Because the enamel on the surface of the pot holder turns red when heated at high temperatures, and due to the special material of the enamel, a flame will appear around the pot holder that is red. This is the color of metal ions at high temperatures. . Therefore, the red fire is not a problem with the stove, but caused by the above reasons. It will not affect normal use and will not cause harm to human health.

5. What should I do if a yellow flame appears on the gas stove? The occurrence of yellow flame is caused by insufficient combustion; at this time, the yellow flame problem can be solved by adjusting the damper to increase the amount of air entering.

6. What should you do when the gas stove fails to light up? If the gas stove fails to ignite, you should check according to the following procedures: First, check whether the gas source switch is on. If it is on, then secondly, check whether the connecting hose is flattened. Or press and bend. If it is not flattened or bent, then, finally, pick up the pot support and see if there is fire at the ignition nozzle

1. If there is no fire, check whether the discharge needle is discharged

p>

a. If the discharge needle does not discharge, it means that the discharge needle is faulty and should be replaced.

b. If the discharge needle discharges, it means the valve body is faulty and the valve body should be replaced.

2. If there is a fire:

a. If it can burn normally, it means that the ignition position is too high. The user should be instructed to gently press the igniter down a few times and then put it down. Just put the pot rack on.

b. If there is a fire, but the flame is too weak and cannot reach the burner, the gas pressure is too low. Users of liquefied gas stoves are recommended to replace the pressure reducing valve with a new one, while coal-based gas and natural gas are recommended. This should be reported to the gas supply company.

c. If there is a fire and the flame can reach the fire cover, but it does not catch fire, it means that the valve body is blocked. Instruct the user to use a thin wire to clear the nozzle.

8. What is defire? What should you do when a fire breaks out? Defire occurs when the gas pressure is too high or the air intake is too large, causing the flame to drift away from the fire cover.

When a misfire occurs, the user should first be instructed to correctly adjust the air volume at the damper; then the user's pressure reducing valve should be inspected. If it is natural gas or coal gas, it is caused by excessive pressure in the pipeline, and feedback needs to be reported to the gas supply company. solve.

9. What is tempering? Why does a gas stove backfire? Backfire means that the flame burns into the inside of the burner or even at the damper, and is often accompanied by "chichi" and "hurry" burning sounds; if it cannot be discovered and stopped in time, it may cause burning of the stove or the combustion valve body. There are two reasons for backfire: Reason 1. The fire hole is blocked. Since gas will contain some impurities (such as sulfides) to varying degrees, if the gas stove is used for a long time, dirt will precipitate out of the fire hole of the fire cover, making the fire hole smaller. If there is pressure from gusts of wind or water overflow, the flame will move forward. Retreat, and then backfire occurs. To avoid this situation, the fire holes must be cleaned in time after use for a period of time. Reason 2: Backfire is also prone to occur when the burner is not tightly covered or the air intake volume at the damper is large. Therefore, when backfire occurs, the correct handling procedures are: ① observe whether the fire hole is blocked, ② check whether the fire cover is placed in place, ③ adjust the damper. 4. Replace the pressure reducing valve

10. What should I do if the gas stove emits black smoke? Check whether the gas source used matches the temperament type shown on the nameplate of the gas stove. If they match, the problem can be solved by instructing the user to adjust the damper; if they do not match, the temperament needs to be changed
