Second,battery has no electricity. Founding that gas stoves can’t get fire, they want to check whether the battery has electricity, if not, only need to change the normal one battery on it.

Third, poor contact of the circuit, mainly check the battery box of positive and negative has no rust. The line is no bad contact, if it has, need to remove the rust line accurate connection.

Fourth, over voltage protection. A lot of gas stoves have over-voltage protection function. Once  over voltage, the gas stoves will not started, then try to change a pressure reducing valve.

Fifth, the blockage of the pipeline. Once the pipeline is blocked, it is necessary to check the gas outlet valve, generally can smell gas and gas stove can’t get fire which is likely to gas blockage, when the need of the pipeline dredge.

第一，燃气胶管破裂、脱落容易发生天然气泄漏事故；特别是老房子，胶管老化，如果管道是在室内的话就应该经常检查管道的使用年限。

第二，私改私接燃气管道；这条正好对应我们的出租房。有的用户就是因为管道禁用了，然后私接了一根管道，这种做法是很危险的。

第三，户内燃气管道损坏；这种可能因为家庭装修或者在管道上悬挂物品，是管道脱落。

第四，燃气灶点火引发泄漏；这个原因有很多种，可能是电路接触不良，或者是风门没调节好，导致进空气的口太大，空气太多等等原因。还有燃气表损坏啊，忘记关燃气阀门啊，燃气阀门接口损坏等原因。所以大家平时要对这些可能引起事故多多观察，留意。
