　　2. 廚房排煙罩內安裝的排煙管直接從外墻通到室外，組件應設置在室外排煙口，防止污染和防風。抽油煙機垂直煙道與普通垂直煙道連接的截面應根據排放量的計算確定。

　　2. The exhaust pipe installed in the kitchen exhaust hood directly passes through the outer wall to the outdoor. Components should be set at the outdoor exhaust outlet to prevent pollution and wind. The cross section of the vertical flue connecting with the ordinary vertical flue should be determined according to the calculation of emission.

　　4、如果廚房位于陰臺一側，我們需要注意的是油煙管道是否穿過建筑物的楣板，原則上一般物業管理部門是不允許鉆透楣板的煙道的。這種處理方法可以不需要考慮廚房排氣煙囪和墻壁之間的距離,避免因為廚房排氣煙囪的墻的距離大于吊柜的深度,影響安裝吊柜,而且還能避免完成
