Gas Pipeline Installation Steps:
1. The gas pipeline should be laid along the wall of non-combustible materials, and when it meets other pipelines, it should meet the following requirements:
1) When laying horizontally and in parallel, the net distance should not be less than 150mm;
2) When laying vertically in parallel, the net distance should not be less than 100mm, and should be located on the outside of other pipelines;
3) When cross-laying, the net distance should not be less than 50mm.
2. Under special circumstances, when the indoor gas pipeline must pass through the bathroom, toilet, hanging flat roof (vertical wear) and living room, the pipeline should have no interface.
3. The indoor gas pipe should not pass under the water bucket. When it is necessary to cross, a casing should be added, the diameter of the casing pipe should be two gears larger than the diameter of the gas pipe, the gas pipe and the casing should have no interface, and the two ends of the pipe sleeve should extend out of the side of the bucket 20 20mm.
4. After the installation of the gas pipeline is completed, the tightness test should be carried out, the test pressure is 300mm water column, and the pressure does not drop within 3 minutes to be qualified.
5. Gas appliances, electricity meters, and electrical equipment should be set in dislocation, and the horizontal net distance shall not be less than 500mm. When misalignment is not possible, there should be thermal insulation protection.
6. When the wall of the gas appliance is made of wood or other flammable materials, fire prevention measures must be taken.
7. The distance between the side of all kinds of gas appliances and the wall, water bucket, door frame, etc., and the distance between gas appliances and gas appliances shall not be less than 200mm. When two gas appliances or one gas appliance and the water bucket are arranged at right angles, the sum of the two sides of the wall shall not be less than that.

1. Preparation for stove installation.
Before the installation of the stove, it is necessary to determine whether the air source of the stove is consistent with the air source used, whether the trachea is in place, whether the trachea matches the stove, whether the size of the cabinet opening is consistent with the stove, and whether the cabinet has ventilation holes.
2. The trachea connects the stove and the gas source.
At present, the trachea is mainly divided into stainless steel hose and rubber pipe. Because the stainless steel hose is not afraid of rat bites, it has become a mandatory connecting pipe for natural gas companies because it does not age for ten years; Rubber pipes are generally used more for liquefied gas. When connecting the stainless steel pipe, you must pay attention to the gasket of the connecting port, if there is no gasket or the gasket is reversed, it will leak; The rubber tube must be connected to the corrugated part of the trachea fixed with a bayonet.
3. Check whether the trachea connection of the stove is leaking.
After the initial installation of the cooker is completed, check whether there is any air leakage in the external connection of the cooker, focusing on both ends of the gas source and the connecting pipe of the cooker. Sparkling water such as soapy water or laundry detergent water can be used. Apply it to the side of the trachea of the cooker, if there is air leakage, you can clearly see the bubble blowing, and ensure that the trachea connection of the cooker has no air leakage.
4. Put on the battery to check the stove fire cover, etc.
The cooktops all use No. 1 batteries. Generally, thermocouple cooktops only need 1 battery, and ion-extinguished cooktops require two batteries. Before starting the fire, the fire lid and stove frame of the stove should be arranged.
When placing the fire cover, put it one by one, and turn each piece to ensure that the rotation is smooth for installation.
5. Test the fire and adjust the damper.
Ignite the stove and twist it to the maximum fire position. Experience the smoothness of rotation and torsion, observe the intensity of the electric spark of the cooker, the position of the electric spark is aligned with the air outlet in the center of the cooker, and whether it is easy to ignite during the successful process of ignition. After ignition, observe the combustion, turn off the fire, and then light the fire several times to observe the ignition process.
After lighting the stove, observe the flame burning of the stove. Whether the flame color is mainly blue, whether the root of the flame is at the position of the vent of the fire cover, and whether the flame burns stably.

When choosing a gas water heater, you must choose a plug with a ground wire, that is, a plug with three corners, to prevent accidents in the kitchen during the summer thunderstorm.
The gas water heater must be installed at a sufficient distance from the gas meter, in principle, they are not allowed to be perpendicular to a line, and the horizontal distance needs to be kept at least 30 cm.
The smoke outlet of the gas water heater needs to be discharged directly in the open area outside, which means that the gas water heater must be installed on the wall closest to the outside.
The accessories for installing the water heater need to be provided separately, after all, many are laymen to buy things, when you don't understand, ask the sales consultant to help make a list, and then go to the hardware store to buy it directly according to the list.
If you don't prepare in advance, the installer will also have a belt, of course** must be slightly more expensive. It's up to you to choose.
There are many brands of gas water heaters, if it is for long-term consideration or buy a better one, the biggest point of attention of gas water heater is the way to ignite, after a long time, the gas water heater switch may not be able to ignite, so it is still a penny for the price.

The installation of gas pipelines should be practical and good-looking, so you have to pay attention to the precautions, what are the precautions for the installation of gas pipelines? Today, PCHOUSE will answer them for you one by one.
1. The indoor gas pipeline should not cross under the water bucket. When it is necessary to cross, a casing should be added, the diameter of the casing pipe should be two gears larger than the diameter of the gas pipe, the gas pipe and the casing should have no interface between the branches, and the two ends of the casing should extend out of the side of the bucket 20mm.
2. When co-erecting and laying with the pipeline transporting corrosive medium, the gas pipeline should be erected above. For parts that are prone to air leakage, oil leakage, and corrosive liquid leakage, such as flanges, valves, etc., protective measures should be taken on the gas pipeline.
3. Pipelines, pipe fittings, valves, etc. should be inspected according to national standards; Sweep before installation to ensure cleanliness; If the pressure is concealed and the ventilation is very convincing, this is often ignored, and it is an important measure to ensure safety and no air leakage, and the pipeline shall not be harmed during concealed construction.
A gas pipe is a special pipeline that transports combustible gas. For gas pipes used in households, ordinary users generally use 4 pipes, and gas heating users use 6 pipes. The difference between the 4 pipes and the 6 pipes is that the pipe diameter is different, the 4 gas pipes are as thick as the indoor water pipes, and the 6 gas pipes are thicker than the 4 pipes. >>>More
The method of opening the gas self-closing valve is to open the plug valve by hand, and the direction of the handle needs to be parallel to the direction of the pipeline. Gently pull the lift up and pull it to the position of the first switch. >>>More
