With the increasing demand for winter heating, energy-saving and efficient fully premixed condensing wall mounted boilers have gradually become the first choice for many households. However, in order to fully utilize the performance of fully premixed condensing wall mounted boilers, the correct installation process is crucial. Many users only focus on the product itself of the fully premixed condensing wall mounted boiler, but ignore the installation details, ultimately leading to increased energy consumption, shortened service life, and even safety hazards. Today, let's take a detailed look at the core points that must be paid attention to when installing a fully premixed condensing wall mounted boiler at home, to help you avoid installation pitfalls.

1、 Before installation: Make basic preparations to avoid rework in the later stage

Installing a fully premixed condensing wall mounted boiler is not a "buy and install" process. Whether the preparation is in place in the early stage directly affects the quality of subsequent installation and user experience. Two key points should be focused on:

1. Accurately select the installation location

The installation position of the fully premixed condensing wall mounted boiler has strict requirements and cannot be placed arbitrarily. Firstly, it is necessary to ensure good ventilation in the installation environment, as sufficient air is required for combustion during equipment operation. Enclosed spaces can easily lead to insufficient gas combustion, increasing the risk of carbon monoxide; Secondly, the load-bearing capacity needs to be considered. The fully premixed condensing wall mounted boiler includes accessories such as water tanks and pipelines, and its overall weight is relatively heavy. It is recommended to install it on solid walls (such as load-bearing walls in kitchens and balconies), avoiding installation on lightweight partitions or wooden structures to prevent wall cracking and equipment displacement after long-term use; Finally, stay away from flammable and perishable items, such as gas stoves, range hoods, or cabinets storing cleaning agents and paint. At the same time, be at least 30 centimeters away from sockets, switches, and other electrical appliances to reduce safety hazards.

2. Plan pipeline and circuit layout in advance

Before installation, it is necessary to plan the water, gas, and electrical routes in advance based on the layout of the house and the interface requirements of the fully premixed condensing wall mounted boiler. In terms of waterways, it is necessary to reserve cold water inlet, hot water outlet, and heating return outlet. It is recommended to choose corrosion-resistant PPR pipes for pipeline materials to avoid water leakage in the later stage; The gas pipeline needs to use a dedicated gas pipeline and a separate valve should be installed for easy maintenance and closure in the later stage; In terms of circuits, it is necessary to reserve independent sockets (recommended to be above 16A) for the fully premixed condensing wall mounted boiler, and the sockets should have waterproof function, especially when installed in areas such as kitchens and balconies that may come into contact with water vapor, to avoid short circuit faults.

2、 During installation: Focus on key links to ensure equipment performance

The installation process of the fully premixed condensing wall mounted boiler involves multiple professional operations, and each step cannot be taken lightly. The key is to control three details:

1. Standardize the installation of smoke exhaust systems

Unlike ordinary wall mounted boilers, fully premixed condensing wall mounted boilers generate condensed water and exhaust gas during combustion, and the installation of exhaust systems directly affects equipment efficiency and safety. The smoke exhaust pipe should use a dual core pipe (inner layer for exhaust gas, outer layer for fresh air intake), and ensure a firm installation and good sealing to avoid exhaust gas leakage; The direction of the smoke exhaust pipe should be shortened as much as possible to reduce the number of turns (it is recommended not to exceed 2 90 degree turns). Turning too many times will increase the smoke exhaust resistance, resulting in poor exhaust gas discharge; At the same time, the exhaust pipe outlet should face the outdoor open area, away from windows, balconies, or neighbors' air intakes, to avoid the backflow of exhaust gas or affecting others. In addition, the condensate discharge pipe should also be properly handled and connected to a dedicated drainage pipeline. It cannot be directly discharged to the ground or rainwater pipes to prevent condensate from corroding the ground or freezing and blocking the pipeline.

2. Ensure that the pipeline connection is sealed and leak free

Once the water and gas connections of the fully premixed condensing wall mounted boiler leak, it not only wastes energy but may also cause safety accidents. Professional sealing materials (such as gas specific sealant and raw material tape) should be used during installation to seal the pipeline interface; After the connection is completed, pressure tests should be conducted separately on the water and gas pipelines: the water pipeline test needs to increase the pressure to 0.8-1.0MPa and maintain it for 30 minutes without any pressure drop to be considered qualified; Gas pipeline testing requires applying soapy water to the interface and observing for the formation of bubbles. If there are no bubbles, it indicates good sealing. In addition, the pipes of the heating system also need to be treated with exhaust to avoid residual air in the pipes causing poor water circulation and affecting the heating effect.

3. Accurately adjust the installation angle of the equipment

When installing the fully premixed condensing wall mounted boiler, it should be kept horizontal and not tilted. The installation technician will use a level to calibrate and ensure that the equipment body is in a horizontal state in front, back, left, and right. Tilting installation can cause uneven stress on internal parts, affecting the operation of core components such as water pumps and heat exchangers, and even causing condensed water to be unable to be discharged normally, damaging the internal structure of the equipment. At the same time, at least 10 centimeters of space should be reserved between the equipment and the wall for easy disassembly of the casing during later maintenance and repair.

3、 After installation: carry out debugging and acceptance to ensure normal operation

Installation completion does not mean "everything is fine". The debugging and acceptance of the fully premixed condensing wall mounted boiler is the last key line of defense, which must be confirmed item by item:

1. Conduct comprehensive equipment debugging

Professional installers will debug each function one by one according to the operating parameters of the fully premixed condensing wall mounted boiler. Firstly, test the ignition function and observe whether the ignition is smooth and whether the combustion flame is stable (the normal flame is blue, with no yellow or red flames); Next, adjust the water temperature control by setting different hot water temperatures (such as 40 ℃, 50 ℃) and heating temperatures (such as 50 ℃, 60 ℃), and check whether the outlet temperature is consistent with the set temperature to avoid sudden fluctuations in water temperature; Finally, test the security protection functions, such as simulating scenarios of gas and water outages, to see if the equipment can automatically shut down, ensuring that overload protection, anti dry burn protection, and other functions are functioning properly.

2. Carefully verify the acceptance criteria

During acceptance, users can confirm one by one against the following standards: the appearance of the equipment is free of scratches and deformations; There is no leakage in the pipeline connection; The smoke exhaust pipe is installed firmly and without looseness; There is no obvious noise when the equipment is running (the normal operating noise should be below 50 decibels, similar to the sound of a refrigerator running); Smooth operation of all functional buttons and clear display on the screen; The installer needs to provide detailed installation records, including pressure test data, debugging parameters, etc., and explain basic usage methods and daily maintenance precautions.

4、 Additional note: Choose a professional team to avoid "unlicensed installation"

The installation of fully premixed condensing wall mounted boilers involves professional fields such as gas, water and electricity, and must be operated by a qualified installation team. Many users choose to install without a license in order to save costs, which not only fails to guarantee installation quality, but may also cause equipment damage due to improper operation, and even lead to safety accidents such as gas leaks and fires. It is recommended to choose an official installation team that cooperates with the brand, or professional personnel holding a "Gas Appliance Installation and Maintenance Qualification Certificate". Before installation, qualification certificates can be required, and after installation, the installation certificate should be kept for traceability in case of problems in the future.

In short, installing a fully premixed condensing wall mounted boiler at home requires meticulous control at every stage from preparation to acceptance. Only by doing these installation points well can the fully premixed condensing wall mounted boiler achieve the best energy-saving effect and heating performance, bringing a stable and safe warm experience to households. If you encounter any questions during the installation process, it is recommended to consult professionals in a timely manner and not adjust or modify the installation plan on your own to avoid unnecessary losses caused by improper operation.
