When buying a burner water heater in JD.COM, does the natural gas company in Hanzhong touch gas?

Give it to me. The gas supply system, gas meter and pipeline transportation system are all installed and managed by the gas company. Because of security problems, outsiders can't touch it. You can contact Hanzhong gas company to send someone to install it, but there is an extra charge. If it is installed by the production and sales unit, it must be approved by the gas company. You can contact the gas company in advance. Therefore, we bought a gas water heater for gas connection in the natural gas company in Hanzhong City, JD.COM.
