一、副煙道務必保留
First, the auxiliary flue must be retained
每家的廚房里都有煙道，同時煙道也有主副之分，主煙道貫穿整個樓體，而副煙道是相對獨立的。一般家里的油煙會先到副煙道里，然后再通過隔板上的孔進入主煙道，這樣可保證每戶的油煙是隔離開來的。而如果將副煙道直接連接主煙道，就會由于壓力過低而導致倒煙或串煙現象。
Each house has a flue in the kitchen, and the flue also has the main and the main points. The main flue runs through the whole building, and the auxiliary flue is relatively independent. The oil smoke in the home will go first in the auxiliary flue and then into the main pipe through the hole on the partition, which ensures that the oil smoke in each household is isolated. And if the side flue is directly connected with the main flue, will lead to smoke or smoke phenomenon due to low pressure.
二、施工細節要注意
Two. Attention should be paid to the details of the construction
，選擇抽油煙機安裝的位置十分重要。管道越短越好。一些業主會為了美觀，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。另外，為了不破壞原有的主副煙道，其開口方向不是隨意可以改的，一定要打在副煙道里面。
First, it is very important to choose the location of the installation of the smoke pump. The shorter the better the pipe. Some owners in order to pull the pipe appearance, is relatively long, so, turn off the lampblack machine, the pipe will gather a lot of fumes discharged out, and then back to the room. In addition, in order not to destroy the original main and auxiliary flue, its opening direction is not arbitrary can be changed, must be hit in the auxiliary flue.
三、窗戶排煙注意
Three, window smoking attention safety
一些業主為了避免串煙問題，放棄原有煙道，直接在窗戶上開孔排煙，這樣做是可以的，但有幾點需要注意。
Some owners in order to avoid the problem of smoke, give up the original flue, direct holes in the window and exhaust smoke, so do it, but there are a few points to be paid attention to.
在窗戶或墻面開洞之前一定要經過物業的同意;其次注意問題，一般排煙管末端是金屬材質的，如果開的洞太小，金屬傳熱可能會使玻璃炸裂，傷及行人，且煙管通向窗外，強勁的北風對著吹會導致油煙倒灌。好將管道伸出去以后把管道往下窩，這樣還可以避免下雨時雨水流進管道，并把風擋在外面。
First, before the window or wall openings must go through the consent of the property; second Caution!, general smoke at the end of the tube is made of metal material, if the hole is too small, the metal heat transfer may cause cracking of glass, and pedestrians, and the smoke pipe to the outside, the strong north wind blows will lead to soot intrusion. It is best to put the pipe out and put the pipe down to the bottom, so it can avoid the rain water flowing into the pipe when it rains, and keep the wind out.
四、止逆閥門勤更換
Four, check and reverse valve frequently change
如果已經把副煙道拆除，或是需要防止倒煙的效果更好，那么使用煙道止逆閥。一般情況下，油煙機的止逆閥效果不是很明顯，而在煙道安裝止逆閥可以保護油煙機，使煙道里的煙不會向管道和抽油煙機內倒灌。不過，安裝止逆閥后要定期清洗，否則會使止逆閥呈打開狀態，失去效果，而且煙道止逆閥好兩年左右就更換一次。
If you have the side flue removed, or need to better prevent smoke, then use flue non-return valve. Generally speaking, the effect of the check valve is not very obvious, and the installation of check valve can protect the smoke hood, so that the smoke in the flue will not be poured into the pipe and range hood. However, after installing the check valve, it should be cleaned regularly. Otherwise, the check valve will be opened and lose its effect. And the flue check valve should be replaced for about two years.
