1. Indoor gas pipelines are generally installed indoors from underground, and non-heating areas can be set outdoors, and then enter indoors after leaving the ground.
2. Pipes are generally installed in corridors, stairs, kitchens or auxiliary rooms. Pipes shall not be laid indoors and underground, installed in bedrooms, or passed through power distribution rooms, flues, air intake pipes, etc. , can be hidden when there are special requirements.
3. The distance between the pipeline and water supply and drainage, heating and hot water supply pipelines and wires shall not be less than 5cm, and the distance between the pipeline and distribution box, electrical switch and connector shall not be less than 30cm.
4. The layout and direction of pipelines should meet the design requirements. Under no circumstances should the pipeline tilt to the gas meter. The gas pipeline passing through the casing shall have no joint. The valve should be a special air valve. The distance from the back of the gas meter to the wall is 1cm ~ 2cm. The gas meter should be installed correctly, and the inlet and outlet risers should not be skewed.
As you said, the gas company is responsible, but I suggest you consult professionals in detail.
