The correct installation of kitchen exhaust ducts is crucial for maintaining fresh kitchen air and effectively eliminating smoke and oil fumes. The following are the general steps for installing kitchen exhaust ducts:

規劃和設計：

Planning and Design:

在安裝排煙管道之前，需要進行規劃和設計，確定管道的走向和位置。考慮廚房布局、煙機位置和出口位置等因素，確保排煙管道的布置合理。

Before installing smoke exhaust ducts, planning and design are necessary to determine the direction and location of the ducts. Consider factors such as kitchen layout, fan position, and outlet position to ensure the reasonable layout of smoke exhaust ducts.

準備材料和工具：

Prepare materials and tools:

根據設計要求和管道尺寸，準備所需的排煙管道材料，如鍍鋅鋼管、鋁管等。同時，準備安裝所需的工具，如切割工具、螺絲刀、螺絲扳手等。

According to the design requirements and pipeline size, prepare the necessary smoke exhaust pipeline materials, such as galvanized steel pipes, aluminum pipes, etc. At the same time, prepare the necessary tools for installation, such as cutting tools, screwdrivers, screw wrenches, etc.

安裝煙機：

Installation of smoke hood:

安裝煙機是排煙管道安裝的步。將煙機固定在廚房墻壁或吊頂上，并根據煙機的出口位置和尺寸確定排煙管道的起始點。

Installing the smoke exhaust fan is the first step in installing the smoke exhaust duct. Fix the smoke exhaust fan on the kitchen wall or ceiling, and determine the starting point of the smoke exhaust pipeline based on the outlet position and size of the smoke exhaust fan.

安裝排煙管道：

Install smoke exhaust ducts:

切割管道：根據設計要求和實際情況，使用適當的工具將排煙管道切割成所需的長度和形狀。

Cutting pipes: According to the design requirements and actual situation, use appropriate tools to cut the smoke exhaust pipes into the required length and shape.

連接管道：使用合適的連接件（如彎頭、接頭等）將排煙管道連接起來，確保連接緊密，并使用螺絲或螺母進行固定。

Connecting pipes: Connect smoke exhaust pipes with suitable connectors (such as elbows, joints, etc.) to ensure tight connections and secure them with screws or nuts.

固定管道：將排煙管道固定在墻壁、吊頂或天花板上，確保管道穩固且不會晃動。

Fixed pipeline: Fix the smoke exhaust pipeline to the wall, ceiling or ceiling to ensure that the pipeline is stable and does not shake.

安裝排煙出口：

Install smoke exhaust outlet:

安裝排煙出口是確保排煙管道能夠有效排出煙霧和油煙的關鍵步驟。根據設計要求，安裝合適的排煙出口，如排煙風帽或排煙口，確保其與管道連接緊密且密封良好。

Installing smoke exhaust outlets is a key step in ensuring that smoke exhaust ducts can effectively exhaust smoke and oil fumes. According to the design requirements, install suitable smoke exhaust outlets, such as smoke exhaust hoods or smoke exhaust outlets, to ensure that they are tightly connected to the pipeline and well sealed.

檢查和測試：

Inspection and testing:

在完成安裝后，進行排煙系統的檢查和測試。確保排煙管道連接牢固、無泄漏，并進行排煙系統的測試，檢查是否正常運行，有效排除煙霧和油煙。

After completing the installation, inspect and test the smoke exhaust system. Ensure that the smoke exhaust pipes are securely connected and leak free, and conduct testing of the smoke exhaust system to check for normal operation and effectively eliminate smoke and oil fumes.

需要注意的是，在安裝排煙管道時應遵守相關的規范和建筑標準，確保管道安裝牢固、排煙效果良好，并確保使用合適的材料和配件。

It should be noted that when installing smoke exhaust pipes, relevant safety regulations and building standards should be followed to ensure that the pipes are firmly installed, the smoke exhaust effect is good, and appropriate materials and accessories should be used.
