After using the portable stove for a period of time, the flame may become smaller due to external factors such as weather and dust, and sometimes it may not ignite at all. When encountering these issues, consumers should not blindly disassemble the device. Experts have provided a detailed answer to these common problems. If you encounter issues with the portable stove, you might want to pay attention to this:

What measures should be taken when the flame of the portable stove is low?

The normal flame of a portable stove is light blue, with a clear inner flame, a height of about 60mm, and a slight noise, indicating strong power. If the flame is very small, the reasons and solutions are as follows:

(1) The burner cap holes are blocked by dirt, hindering the flow of mixed gas from the burner. Clean the holes.

(2) The nozzle is blocked; unscrew the nozzle and clean it.

(3) The inlet of the regulator and the nozzle are blocked by rust, hindering the gas flow from the bottle. Replace with a qualified regulator.

(4) The copper pipe is flattened, obstructing airflow. Straighten the copper pipe or replace it.

(5) Additionally, if the gas is about to run out or the valve is not fully opened, these reasons should also be noted, and corresponding measures can be taken to resolve them.

Is it normal for the portable stove to have a red flame? Why does the portable stove have a red flame?

The appearance of a red flame in a portable stove is mainly caused by the following reasons:

(1) Gas reasons: When the burning gas contains too much moisture or impurities, the flame color will appear red.

(2) Dust reasons: When there is dust in the room or when cooking, the moisture and oil vapor in the air increase, which can also easily lead to a red flame.

(3) Air damper reasons: If the air damper is not adjusted properly, this situation may also occur.

(4) Support frame reasons: The surface enamel of the support frame turns red when heated to high temperatures. Due to the special materials of the enamel, a red flame may be observed around the support frame, which is the color of metal ions at high temperatures.

Therefore, the appearance of a red flame during combustion does not indicate a problem with the stove, but is caused by the reasons mentioned above. It will not affect normal use and will not harm human health.

What should be done when the portable stove cannot ignite?

If the gas stove cannot ignite, the following procedures should be followed for inspection:

First, check whether the gas source switch is in the open position. If it is open, then check whether the connecting copper pipe is flattened or bent. If it is not flattened or bent, finally, lift the support frame and check whether the ignition nozzle is emitting flames:

(1) If there is no flame, check whether the discharge needle is discharging. a. If the discharge needle is not discharging, it indicates a fault with the discharge needle, and it should be replaced. b. If the discharge needle is discharging, it indicates that part of the gas path is blocked or there is a fault with the valve body, and the valve body should be replaced.

(2) If there is a flame: a. If it can burn normally, it indicates that the igniter is positioned too high. The user should be guided to gently press the igniter down a few times and then place the support frame back on. b. If there is a flame, but it is too weak to reach the burner, it indicates that the gas pressure is too low, possibly because the gas bottle is nearly empty or the adjustment valve is malfunctioning. c. If there is a flame, and it can reach the burner cap but does not ignite, it indicates that the valve body is blocked, and the user should be guided to clear the nozzle with a fine wire.
