1. Firstly, it is necessary to check if there is any space and position reserved for the upper part of the flue opening due to the downward movement of the ceiling.

2、吊頂之前將煙機排煙管預埋進吊頂上部，需要根據櫥柜的設計圖紙來確定排煙管在吊頂上外露口的位置，需要參照的還有煙機的款式，一般說歐式煙機的管道是在中間位置，而中士煙機的排煙管口卻在煙機的一側。這些情況影響著預留口的位置。

2. Before suspending the ceiling, embed the smoke exhaust pipe of the smoke exhaust fan into the upper part of the ceiling. It is necessary to determine the position of the smoke exhaust pipe at the exposed opening on the ceiling based on the design drawings of the cabinet. It is also necessary to refer to the style of the smoke exhaust fan. Generally, the pipes of the European style smoke exhaust fan are in the middle position, while the smoke exhaust pipe of the sergeant smoke exhaust fan is on one side of the smoke exhaust fan. These situations affect the location of reserved openings.

3、在預埋排煙管時注意封閉住煙道口的縫隙，并保證其牢固不脫落。

3. When embedding the smoke exhaust pipe, pay attention to sealing the gaps at the flue opening and ensuring that it is firm and does not fall off.

4、如果灶具安置在陰臺一側，就需要注意排煙管道是否通過樓房的過梁的問題，原則上物業管理部門是不允許在過梁打孔穿越排煙管的。這種處理方式1可以不必考慮煙道口與墻壁之間的距離，避免了因為煙道口距墻的距離大于吊柜的進深而影響到吊柜的安裝，2可避免完成安裝后吊柜頂部留有一段橫向煙機排煙管而影響美觀。

4. If the stove is installed on the side of the shade, it is necessary to pay attention to whether the smoke exhaust pipe passes through the lintel of the building. In principle, the property management department does not allow drilling holes in the lintel to pass through the smoke exhaust pipe. This treatment method 1 does not need to consider the distance between the flue port and the wall to avoid affecting the installation of the hanging cabinet due to the distance between the flue port and the wall being greater than the depth of the hanging cabinet. 2 can avoid leaving a horizontal smoke exhaust pipe at the top of the hanging cabinet after installation, which affects the aesthetics.

5、此種方式不可避免的會在吊頂與煙機上部露出部分上下走引的管道，朋友們可根據這個管道的位置和高度設計包管板等來加以修飾。此種方法利于排煙的通暢和整體布局的美觀。

5. This method inevitably leads to pipes running up and down on the exposed parts of the ceiling and the upper part of the smoke machine. Friends can design a pipe plate or other modifications based on the position and height of this pipe. This method is beneficial for smooth smoke exhaust and aesthetic overall layout.
