Why didn't Wanhe water heater spontaneously ignite in a short time? Ask the after-sales person that the gas in Nanchang is too dirty. Is it only dirty in Nanchang in the whole country?

first, confirm two viewpoints;

first, the local gas supply for residents does not meet the supply standards; It must be said that residents have used gas for many years and there is no adverse reaction on other appliances; This is the basic affirmation of the gas standard;

second, as a water heater using gas as I energy, it also meets the standards implemented by manufacturers; The problem is that the attachment does not conform to the standard that the energy used by the appliance is given to "gas".

Find out these two problems, and let the water heater suppliers and the gas company theorize to confirm the legality of the two product standards.
