Installation technology of gas water heater Matters needing attention in installation drawing of water heater

The water heater is convenient for us to take a bath and is one of the necessary bathroom equipment for furniture. But many friends are worried that the gas water heater is unsafe to use after installation. In fact, as long as the water heater is installed correctly and used according to the instructions, it is very safe. The following small series shares the installation methods and precautions of gas water heaters.

First, the gas water heater installation method:

1. Unpacking inspection

Whether you buy a water heater online or in a shopping mall, your friends must pay attention. No matter where you buy a water heater, you must wait for the installer to install it for you. Because if there is something wrong with unpacking, many businesses will not give three guarantees. After unpacking, check whether the accessories are complete, and whether the instruction manual and three-guarantee certificate are complete. Check the attachment with reference to the instruction manual.

2. Pipe laying and valve installation

Insert the special threaded pipe for gas water heater into the reserved position, and the reserved hole should be slightly larger to avoid re-drilling and rework. If the hole is rough, it can be covered with a cover after the water heater is installed, and then fixed with glass glue. Before installation, completely close the water valve at home to prevent "flooding", and then install the hot water valve on your left and the cold water valve on your right.

3. Install the air valve

When the gas pipeline of the water heater is connected with the gas meter, a triangle valve needs to be installed, and the gas pipeline originally used only for cooking stoves is changed into a pipeline used for cooking stoves and water heaters. It is best to choose a ball valve, which is more convenient to switch.

4. Install the smoke exhaust pipe

The smoke vents are all designed by the developer and reserved. Therefore, it is best to arrange the smoke exhaust pipe in front of the water heater wall, otherwise the position is not easy to adjust. The cover between the exhaust pipe and the wall is best made of metal, and the plastic material originally reserved is best not used, because the temperature of the exhaust pipe will be very high when the water heater is used, and the plastic cover will be baked. Pay attention to the high inside and low outside to prevent rainwater from flowing backwards.

5. Make a hole before installing the water heater.

It is necessary to measure in detail to determine the installation position of the water heater, and then draw a hole in the wall with a pen and punch it. After drilling the hole with an expansion screw, lift the water heater first, then define the position of the hole below, and then drill it with an electric drill.

6. Adjust the water heater after installation

After the water heater is on the wall, it needs to make the final adjustment. The yellow hose outside the threaded pipe needs to be cut off, so as to ensure the appearance. After everything is installed, do debugging work.

Second, the gas water heater installation matters needing attention

1. The installation of gas water heater needs to be fully arranged in the stage of hydropower transformation. There are three pipes related to gas water heater: cold water inlet pipe, hot water outlet pipe and gas inlet pipe. It should be noted that the positions of these three pipes are different for different models of gas water heaters, so you need to determine the model of the gas water heater you bought first, and then reserve the positions of these three pipes according to the actual model of the machine.

2. Another point that is often overlooked is that the gas water heater still needs electricity, so it is necessary to reserve a socket for the gas water heater (preferably a socket with a switch).

3. Because water pipes generally go up, they usually go up from the hot and cold water inlets of gas water heaters, and the position of water pipes in the future is generally just in the middle of the installation of water heaters. It should be noted here that since fixing the gas water heater requires nailing on the wall, the pipe should be taken away from the place where it needs to be fixed. Similarly, the circuit wiring of the reserved socket of the gas water heater should also be avoided.

4. At present, gas water heaters are forced-discharge type and need to be discharged outdoors. Generally, this gas has a certain temperature, so the exhaust pipe of gas water heater is made of metal. In the future, this metal exhaust pipe also has a temperature. Therefore, we should pay attention to avoid the exhaust pipe of the range hood, which is generally in the ceiling, because the exhaust pipe of the range hood is made of plastic, and it is easy to age and damage after long-term local heating.

5. Some models of gas water heaters can be installed in cabinets, but some models of gas water heaters will not burn fully and even often put out fires. Please consult a professional for details. Even if the gas water heater can be installed in the cabinet, it should be ventilated as much as possible. For example, the cabinets and hanging cabinets here should not be equipped with upper and lower plates and shutters.

Installation height of gas water heater

The design height of each family bathroom is different, so there is no fixed height for installing water heaters. When installing a water heater, we should decide according to many factors. The most important factor is the overall height of your bathroom, as long as it is suitable for home use.

When installing, you must consider the living habits of your family. You can't put it too high and out of reach, but you can't put it too low to avoid being damaged by children's play. The overall installation is for family comfort, and there is no mandatory requirement for height.

However, the most basic condition for installing a forced-row water heater is that the room is higher than 2.4m, and the installation height of the water heater is 1.2 ~ 1.5m from the ground to the bottom of the water heater. The installation distance from other household appliances should also be moderate to avoid failures and unnecessary troubles. It is best to install in a well-ventilated place, and it is not allowed to be located in the bedroom, basement, living room, bathroom or closed room.

At present, the water heaters bought in the market are basically installed, so the installation is very simple. Just hang the water heater on the wall, nail the expansion screw where it needs to be installed, and then align the hook of the electric water heater and hang it as firmly as possible.

Installation position requirements of gas water heater

1, gas water heaters are strictly prohibited to be installed in bathrooms, bedrooms, basements, living rooms and cabinets.

C) Close to stairs and safety exits (not limited to 5 meters away); ? D) in the cupboard.

2, gas water heater installation must be installed according to the performance characteristics of the water heater exhaust pipe, exhaust hole (cylinder). Attachment: Installation Instructions for Double Smoke Pipes of Balanced Water Heater

3. The installation space of gas water heater must keep convection ventilation with the outdoor. There shall be no exposed wires and electrical equipment above the installation position of the water heater, and gas cookers such as gas cookers and gas cookers shall not be set below. The water heater must be equipped with separate water inlet valve and air inlet valve, which is convenient to switch. The installation height of the water heater should be easy to observe.

4. The water heater should be installed on a solid fire-resistant wall, and the hook should be solid and reliable. After installation, make sure that the car body is vertical and does not tilt.

5. The connecting parts at both ends of the trachea must be fixed with pipe clamps to prevent falling off, and the connecting trachea should not be near the top of gas appliance to prevent the ignition accident caused by thermal radiation.

6. Flammable, explosive and corrosive gases cannot be stored in the installation place of water heater.

7. There shall be no exposed wires, electrical equipment and gas pipelines above the installation position of the water heater, and no gas stoves, gas cookers and other gas appliances shall be placed below.

8. The installation parts of the water heater should be made of nonflammable materials. If the installation part is made of combustible or nonflammable materials, a heat shield should be used for heat insulation, and the distance between the heat shield and the wall should be greater than10 mm. ..

9. The wall-mounted water heater shall be installed vertically and shall not be tilted. ? There are many problems caused by improper installation of water heaters. The installation position of the water heater is not suitable. Many people have encountered this situation. After the water heater is installed, they always feel that it occupies a large area or is inconvenient to use. Because it is far from the water intake point, or the installation position is low, it is easy to encounter, wasting water. There are many problems caused by improper installation position. ? Pay attention to installation location? Too high to operate, too low to suppress, may encounter? The pipeline is too long and wastes energy. Affect the comfort of using hot water. ? In order to reserve enough space, it is difficult to choose products? Because there is no reserved pipeline, the installation is not beautiful. ? A reserved position is left on the hollow wall, and all schemes need to be adjusted. ? The above is a description of the installation location of the gas water heater, and it must be installed according to the installation instructions in the manual of the gas water heater.

Installation cost of gas water heater

It is said that the factory will install it at home for free, but the necessary accessories should be ready. If not, the installer can provide it at a price much higher than the market price. Others, such as the extension of the exhaust pipe, are charged separately.

I can prepare my own accessories: two angle valves (one hot and one cold), one air valve and two stainless steel bellows.

If you don't prepare it yourself, these expenses will add up to more than 100 yuan. If the length of exhaust pipe and elbow is added, it is estimated to be above 200 yuan.
