Installation of exhaust pipe of lampblack machine:

　　安裝方法，將排煙管一頭插入止回閥出風口內外圈之間槽口，用螺釘緊固。另一頭直接通過預留孔伸入室外。如排煙管是通入公用煙道，一定要用公用煙道防回煙止回閥連接，并密封好。若排煙到墻外，則建議在排煙管外裝上百葉窗，避免回灌。排煙管道一般直徑15公分和18公分，但現在市場流行的都是15公分。洞口留小再擴充很方便，留大了要改小也不難，但萬一密封不好就容易返味了。

　　Installation method: insert one end of the exhaust pipe into the slot between the inner and outer rings of the check valve outlet, and fasten it with screw. The other end extends outdoors directly through the reserved hole. If the exhaust pipe is connected to the public flue, it must be connected with the public flue anti-return smoke check valve and sealed well. If smoke is discharged outside the wall, it is recommended to install shutters outside the exhaust pipe to avoid backfilling. Smoke exhaust pipes are generally 15 cm in diameter and 18 cm in diameter, but now they are popular in the market are 15 cm. It's convenient to keep the opening small and expand it again. It's not difficult to change the opening large, but if the sealing is not good, it's easy to retell.

　　濟南排煙管道廠家講解一下抽油煙機排煙管安裝注意事項：

　　Jinan smoke exhaust pipe manufacturer explained the matters needing attention in the installation of smoke exhaust pipe of lampblack machine:

　　我們需要檢查油煙管道口是否有吊頂下移從而在上部所預留的空間和位置的條件。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。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。若排煙到共用煙道，勿將排煙管插入過深導致排煙阻力增大。若是通向室外，則務必使排煙管口伸出75px。排煙管伸出戶外或通進公用吸冷風煙道，接口處要嚴密，不允許將廢氣排到熱的煙道中。抽油煙機管道越短越好，如果把管道拉得比較長，這樣一來，關掉油煙機后，管道里還會集聚很多油煙排不出去，再倒回室內。

　　We need to check whether there is any condition for the ceiling to move downward so as to reserve space and position on the top of the pipeline. When pre-burying the exhaust pipe, attention should be paid to closing the gap of the flue outlet and ensuring that it does not fall off firmly. Before the ceiling, the smoke exhaust pipe of the smoke machine is embedded in the top of the ceiling. It is necessary to determine the position of the smoke exhaust pipe on the top of the ceiling according to the design drawings of the cabinet. The style of the smoke machine needs to be consulted. Generally speaking, the pipe of the European smoke machine is in the middle position, while the smoke exhaust pipe of the sergeant smoke machine is on the side of the smoke machine. If the smoke is exhausted to the common flue, do not insert the exhaust pipe too deep, which will increase the smoke resistance. If it leads outdoors, it is necessary to make the outlet of the exhaust pipe extend 75px. The exhaust pipe extends outdoors or enters the public cold-air suction flue. The interface should be tight, and the exhaust gas should not be allowed to be discharged into the hot flue. The shorter the pipe is, the better. If the pipe is pulled longer, then after turning off the hood, there will be a lot of smoke gathered in the pipe, which can not be exhausted, and then poured back into the room.

　　排煙管安裝要求：

　　Installation requirements of exhaust pipe:

　　排風出口到機體的距離不宜過長，轉彎半徑盡可能大且少轉彎，否則影響排煙效果。排煙管伸出戶外或通進共用吸冷風煙道，接口處要嚴密，不需將廢氣排到熱的煙道中。出風管不宜太長，好不要超過2米，而且盡量減少折彎，避免多個90度折彎，否則會影響吸油煙效果。

　　The distance from the exhaust outlet to the body should not be too long, and the turning radius should be as large as possible and less turning, otherwise the smoke exhaust effect will be affected. The exhaust pipe extends outdoors or enters the common cold air suction flue. The interface should be tight, and the exhaust gas need not be discharged into the hot flue. The outlet duct should not be too long, preferably not more than 2 meters, and minimize bending, avoid more than 90 degrees bending, otherwise it will affect the smoke absorption effect.
