How to install a wall-hung boiler? The wall-hung boiler has a powerful home central heating function, which can set the comfortable temperature at will according to the needs, and can provide a large flow of constant temperature sanitary hot water for family bathing, kitchen and other places. Furnace installation method.
Wall-hung boiler installation requirements source website: Installation conditions
First of all, the heating system of the user’s home must be an independent system, that is to say, the home is a newly installed heating system, according to the independent heating system The way to design and construction; or the wall-hung boiler has been used as a heat source for heating before, and now I want to replace it with a high-grade wall-hung boiler.
Secondly, there must be a gas supply in the home; there is a suitable wall-hung boiler installation site to hang the equipment and ensure that the burning exhaust gas can be discharged smoothly.

The installation location of the wall-hung boiler should first consider the requirements of smoke exhaust, rain protection, and frost protection; secondly, consider whether the direction of the supervisor is reasonable and the household owner’s requirements for the overall appearance of the building. Install it in a location that is easy to operate and easy to maintain, mainly including: kitchen, equipment room (balcony), exterior wall, etc. Avoid installing it in wet bathrooms. Special reminder: If the wall-hung boiler is installed outdoors, it is necessary to perform antifreeze treatment on the wall-hung boiler and other ancillary equipment.

The first is the sub-catchment installation. Construction should be carried out before the house decoration, trenches are dug on the ground, and heating pipes are pre-buried; after the house decoration is completed, the boiler and radiator will be installed. Second, for users whose houses have been renovated, the heating pipes are installed by open pipe welding.

The five principles of “one close, two dry, three full, four incline, and five good” for the small squirrel wall-hung boiler should be followed during installation: near means the distance between the wall-hung boiler and the heating system , air source, water source, power supply, and exhaust outlet as close as possible; dry means to choose a well-ventilated and dry indoor location; full means that the supporting accessories required for the operation of the wall-hung boiler must be fully installed, such as indoor temperature controller, Tap water pressure reducing valve, gas filter, water filter, etc.; oblique, that is, the chimney must be installed outwards and inclined downward within 5 degrees to prevent rain, snow or condensed water from flowing back into the wall-hung boiler; well, it is the wall-hung boiler The installation materials should be good, and inferior pipes, valves and fittings should not be used.

The installation of gas wall-hung boilers should be properly installed by professionals. When installing a gas wall-hung boiler, first choose a suitable installation location. It is recommended that the user install the kitchen or the north balcony, which is convenient for installing the fan port and easy to discharge exhaust gas when the boiler is working; it is best not to install it in the bathroom, so as to avoid the humidity in the bathroom. , corrodes the machine.
Installation method of the wall-hung boiler
1. The wall-hung boiler should be installed and fixed on the wall. Water pipes, line pipes, gas pipes and other pipes should not be pre-buried on the wall and the back of the wall-hung boiler to avoid installing the wall-hung boiler. was broken.
2. When drilling and fixing the hook on the back of the wall-hung boiler, use a spirit level to measure it. Do not observe with the naked eye by experience, so as to avoid the tilt of the wall-hung boiler and repeated drilling, which will cause the wall-hung boiler to be unreliably fixed. If the wall is dry-hanging marble, the general contractor must be informed to reserve a fixed point for the wall-hung boiler in advance.
3. When installing the smoke pipe, the smoke pipe must be inclined downward horizontally at 3-5 degrees to prevent rainwater and condensed water from pouring back into the wall-hung boiler, causing damage to the wall-hung boiler. The size of the hole reserved for the smoke pipe is generally a round hole with a diameter of 120mm. In principle, if all the pipes are straight sections, the longest length is 4m. For each additional pipe elbow, the straight section will be reduced by 1m accordingly. After the installation of the wall-hung boiler, it must be ensured that: 10cm left and right, 30cm up and down, and 60cm in front of it without debris and other equipment, so as to facilitate operation and maintenance.
4. When installing the main heating pipeline, gas pipeline, and domestic water pipeline, it is necessary to ensure that the gasket and the raw material tape are filled in place to prevent the occurrence of running and dripping. Installation requirements of the smoke pipe: the length of the smoke pipe is more than 1 meter, and a hanger needs to be installed when it extends out of the outer wall.
Precautions for installation of wall-hung boilers
Installation methods of gas-fired wall-hung boilers: First, the installation of sub-water collectors. Construction should be carried out before the house decoration, trenches are dug on the ground, and heating pipes are pre-buried; after the house decoration is completed, the boiler and radiator will be installed. Second, for users whose houses have been renovated, the heating pipes are installed by open pipe welding.
When installing the wall-hung boiler, a special balanced pipe should be used to ensure that the intake and exhaust are outdoors. At the same time, the outlet of the flue should be selected in a place with smooth air circulation; the exhaust pipe should be inclined downward by 3-5. This will facilitate the outflow of condensed water. Make sure that there is a 220V±10%/50HZ power supply near the point of the wall-hung boiler, and ensure that the wiring is correct. It is forbidden to use gas pipes and water pipes as grounding. Sewage drains, water inlets, air inlets and power supplies should be installed at the wall-hung boilers. Do not store flammable, explosive and corrosive items. No exposed wires, electrical equipment, gas pipelines and other facilities should be installed above for repair and maintenance. , A certain distance should be reserved around the wall-hung boiler, and the installation height should be controlled at 1200-1400mm from the ground. The installation of the wall-hung boiler should also be fully anti-freezing to ensure that the wall-hung boiler and the pipe network will not freeze during the operation and stop period. If the ambient temperature is lower than 5 ℃ before or after installation, the wall-hung boiler is not used , Pay attention to the insulation of the wall-hung boiler to prevent freezing.
