Mianyang Changhong water heater maintenance answer: the use of gas water heater involves fire, water, gas, electricity, the use of the environment is more complex, and consumers in the use of easy to ignore some problems, leading to deflagration accidents, resulting in unnecessary losses.

The "bang" sound is deflagration, which is caused by insufficient air pressure. During the first ignition, because the air pressure is too low, the fire is not ignited. The second time, the air intake is too sufficient, which will lead to deflagration. The following points must be paid attention to in order to prevent deflagration:

1. Remove carbon deposits. After the ignition needle or burner has carbon deposit, sometimes deflagration will occur during ignition, so maintenance personnel must be asked to clean it.

2. Check the battery. When the battery power of flue gas fan is insufficient, it can not be ignited normally during ignition, resulting in gas gathering and deflagration. Therefore, it is necessary to replace the battery with a new one (pay attention to the positive and negative directions during installation).

3. The air source should be suitable. The gas water heater must be installed by professional maintenance personnel of regular manufacturers, so as to avoid the problem of gas source mismatch caused by the user's private installation and the potential safety hazard.

4. The flue machine is installed with smoke pipe. There is a large smoke pipe interface at the top of the flue. If the smoke pipe is not installed, the interface is bound to be exposed, and the inflammables may fall into the water heater through the top, causing fire and causing accidents.

5. Check the gas hose. If there is air leakage at the connection of gas hose or the hose is aged or bitten by rats, it is necessary to check the leakage with soapy water to prevent gas leakage and accumulation, and explosion in case of sparks. According to relevant national standards, the hose must be replaced within two years.
