the water heater is convenient for us to shower and is one of the necessary sanitary equipment for furniture. But many friends are worried about whether the natural gas water heater will be unsafe to use after installation. In fact, as long as the water heater is installed correctly and used according to the instructions, the water heater is very safe. Now let's take a look at the installation methods and precautions of natural gas water heater

installation methods and precautions of natural gas water heater

I. installation methods of natural gas water heater

1. Unpacking inspection

whether you buy water heaters online or in shopping malls, friends must pay attention to it. No matter where you buy water heaters, you must wait until the installer comes to install them for you. Because if there is a problem with unpacking, many businesses do not give three guarantees. After unpacking, check whether the accessories are complete, whether the instructions and three guarantee certificates are complete, and check the accessories with reference to the instructions

2. Pipe laying and valve installation

insert the special threaded pipe of natural gas water heater in the reserved position, and the reserved hole should be slightly larger, so as to avoid re drilling and rework at that time. If the hole edge is rough, you can cover it with a cover after the water heater is installed, and then fix it with glass glue. Close the water valve completely before installation to prevent “ Water overflows the golden mountain ”, Then install the hot water valve on the left in your direction and the cold water valve on the right

3. Install the gas valve

when connecting the gas pipeline of the water heater with the gas meter, it is necessary to install a triangle valve to change the gas pipeline originally only for the stove into a pipeline that can be used for the stove and the water heater at the same time. It is better to choose ball valve, which is convenient to switch

4. Install smoke exhaust duct

the smoke exhaust outlet is uniformly designed by the developer, and the position is reserved. Therefore, it is best to arrange the smoke exhaust duct before the water heater is installed on the 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 to be used, because the temperature of the exhaust pipe will be very high when the water heater is used, which will bake the plastic cover. Pay attention to the high inside and low outside to prevent rainwater from pouring back

5. Hole drilling before water heater installation

detailed measurement is needed to determine the installation position of the water heater, and then use a pen to draw the position of the hole on the wall, and drill a hole. After drilling the hole with the expansion screw, hang up the water heater first, and then delimit the position of the hole below, and then drill a hole again

6. Adjust the water heater after installation

after the water heater is installed on the wall, the final adjustment needs to be made. The Yellow hose outside the threaded pipe needs to be cut off to ensure beauty. After all the installation is completed, do the commissioning work

II. Precautions for the installation of natural gas water heater

1. The installation of natural gas water heater needs to be fully arranged in the hydropower transformation stage. There are three pipelines related to natural 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 from each other, and different types of natural gas water heaters are different, so you need to determine the model of natural gas water heater you buy first, Then reserve the positions of these three pipelines according to the actual model of the machine

2. Another thing that is often ignored is that the natural gas water heater also needs electricity, so it is necessary to reserve a socket for the natural gas water heater (preferably a socket with a switch)

3. Since the water pipes are generally on the top, the hot and cold water inlets of the natural gas water heater are generally upward, and the pipe laying position is generally located in the middle of the installation of the water heater in the future. It should be noted here that since fixing the natural gas water heater requires nailing on the wall, the pipe laying should deliberately avoid the nailing position where the water heater needs to be fixed in the future. Similarly, The circuit wiring of the socket reserved for the natural gas water heater should also avoid the nailing place

4. The current natural gas water heaters are of forced exhaust type and need to exhaust outdoors. This gas generally has a certain temperature, so the exhaust pipe of the natural gas water heater is metal. In future use, this metal exhaust pipe also has temperature. Therefore, the installation of this exhaust pipe should avoid the exhaust pipe of the range hood that is usually in the ceiling, because the exhaust pipe of the range hood is plastic, Long term local heating is easy to aging and damage

5. Some models of natural gas water heaters can be packed into the cabinet, but some models of natural gas water heaters packed into the cabinet will cause insufficient combustion and even frequent fire fighting. For details, please consult professionals. Even if the natural gas water heater can be wrapped in the cabinet, its ventilation should be increased as much as possible. In this case, the cabinet should not be made with top and bottom plates and installed with shutter doors

installation height of natural gas water heater

the design height of each family bathroom is different, so there will not be a fixed height for installing the water heater. When installing the water heater, we should decide according to various factors. The most important factor is the overall height of your bathroom, as long as the installation is suitable for family use

when installing, you must take into account the living habits of your family. You can't put it too high or too low, so as to prevent children from playing and damaging it. The overall installation is to make the family comfortable, and there is no mandatory requirement for height

but the most basic condition for installing the water heater is that the room should be 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 with other household appliances should also be moderate to avoid failure and unnecessary trouble. The best place for installation is the place with good ventilation conditions, and it must not be set in the bedroom, basement, living room, bathroom or closed room

the water heaters on the market are basically installed, so it is very simple to install them. As long as you hang the water heater on the wall, screw the expansion screws where it needs to be installed, then align and hang the hook of the electric water heater, and try to be firm

requirements for the installation position of natural gas water heaters

1. Natural gas water heaters are strictly prohibited to be installed in bathrooms, bedrooms, basements, living rooms and cabinets. In addition, inflammable, explosive and corrosive gas prone items shall not be stored at the installation site. Forced exhaust natural gas water heaters are not allowed in rooms without air supply and exhaust conditions, and forced exhaust water heaters are not allowed in bathrooms. Water heaters shall not be installed in the following rooms and parts: a) bedrooms, basements and living rooms; b) Bathroom (except for forced air supply and exhaust water heater); c) Near stairs and emergency exits (no restriction beyond 5m); d) In the cupboard

2. The installation of natural gas water heater must be based on the performance characteristics of the water heater, and the exhaust smoke pipe and exhaust hole (cylinder) that meet the requirements must be installed. Attachment: installation instructions for double-layer smoke pipe of balanced water heater

3. The installation space of natural gas water heater must maintain convective ventilation with the outdoor. There shall be no exposed wires or electrical equipment above the installation position of the water heater, and gas stoves such as gas ovens and gas stoves shall not be set below. Water inlet and air inlet valves must be installed separately for the water heater, and the opening and closing are convenient. The installation height of the water heater should be easy to observe

4. The water heater should be installed on a solid and fire-resistant wall, and the hook should be firm and reliable. After installation, ensure that the machine body is vertical and not inclined

5. The connecting parts at both ends of the gas pipe must be fixed with pipe clamps to prevent falling off. The connecting gas pipe cannot be close to the top of the gas appliance to prevent ignition accidents caused by thermal radiation

6. Inflammable, explosive and corrosive gas producing articles shall not be stored at the installation place of the water heater

7. There shall be no exposed wires, electrical equipment, gas pipelines above the installation position of the water heater, and gas appliances such as gas ovens and gas stoves shall not be set below

8. The installation part of the water heater should be made of non combustible materials. If the installation part is made of combustible or non combustible materials, heat shield should be used for heat insulation, and the distance between the heat shield and the wall should be greater than 10mm

9. The installation of wall mounted water heater should be vertical and not inclined. There are many problems caused by the improper installation position of water heaters. Many people have encountered this situation. After the water heaters are installed, they always feel that they take up a lot of space or are not convenient to use. It is far away from the water point, resulting in water waste, or the installation position is low, which is easy to meet. There are many problems caused by the improper installation position. Note that the installation position is too high for easy operation, too low for space suppression, and may meet the head of the pipeline is too long, energy waste. Affect the comfort of using hot water. In order to reserve enough space, it is difficult to choose to buy products without reserved pipelines, resulting in unsightly installation. The reserved position is left on the hollow wall, and all plans need to be adjusted. The above is the description of the installation position of the natural gas water heater. Be sure to install it according to the installation instructions in the instructions of the natural gas water heater

installation cost of natural gas water heater

speaking, it is free door-to-door installation by the manufacturer, but the required accessories should be prepared. If they are not prepared, the installer can provide them, and the price is much higher than the market price. Others, such as the extension of the smoke exhaust pipe, also need to be charged additionally

the accessories you can prepare are: two angle valves (one for hot and cold), one gas valve, and two stainless steel bellows

if you are not prepared, these costs generally add up to more than 100 yuan. If you add smoke exhaust pipe lengthening and elbow, it is estimated to be more than 200 yuan

the above installation methods and precautions of natural gas water heater are briefly introduced here. I hope it will be helpful to you. Please look forward to more information
