First close the natural gas valve, open the window to ventilate the room, and then turn on the gas stove to burn the remaining gas, loosen the screw on the hose, remove the throat clamp, and install the hose. Push upwards to ensure that there is no gap between the hose and the joint, and finally tighten the screws.

1. There are two types of natural gas hoses: one is a stainless steel corrugated hose, which has the advantages of anti-aging, high temperature resistance, bite resistance, corrosion resistance, etc. The stainless steel hose often twists will cause air leakage, and it should not be too long. Some parts need to be fixed. After being damaged by external force, it cannot be confirmed with the naked eye, so all must be replaced again.

2. There are three layers of pvc gas hose, the middle layer is the steel wire explosion-proof net, and the other two layers are the black rubber inner tube and the pvc protective layer. The explosion-proof net is to hold the pvc inner tube, and the protective layer is flame-retardant, anti-bite and anti-scratch function. Suitable for liquefied gas is the connection of liquefied gas tanks, which is more convenient to replace than stainless steel corrugated hoses.

 
1. Check the connection between the hose and the joint regularly to see if there is any air leakage or looseness, and close it in time after using it every day to avoid air leakage at night.
2. When using, don't let water overflow, cause extinguishment of open flames, cause blockage of fire holes and leak air, and keep indoor ventilation so that air can flow. The selected hose must be guaranteed for safety and quality.
