一、副烟道务必保留
First, the auxiliary flue must be retained
每家的厨房里都有烟道，同时烟道也有主副之分，主烟道贯穿整个楼体，而副烟道是相对独立的。一般家里的油烟会先到副烟道里，然后再通过隔板上的孔进入主烟道，这样可保证每户的油烟是隔离开来的。而如果将副烟道直接连接主烟道，就会由于压力过低而导致倒烟或串烟现象。
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、施工细节要注意
Two. Attention should be paid to the details of the construction
，选择抽油烟机安装的位置十分重要。管道越短越好。一些业主会为了美观，把管道拉得比较长，这样一来，关掉油烟机后，管道里还会集聚很多油烟排不出去，再倒回室内。另外，为了不破坏原有的主副烟道，其开口方向不是随意可以改的，一定要打在副烟道里面。
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、窗户排烟注意
Three, window smoking attention safety
一些业主为了避免串烟问题，放弃原有烟道，直接在窗户上开孔排烟，这样做是可以的，但有几点需要注意。
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.
在窗户或墙面开洞之前一定要经过物业的同意;其次注意问题，一般排烟管末端是金属材质的，如果开的洞太小，金属传热可能会使玻璃炸裂，伤及行人，且烟管通向窗外，强劲的北风对着吹会导致油烟倒灌。好将管道伸出去以后把管道往下窝，这样还可以避免下雨时雨水流进管道，并把风挡在外面。
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、止逆阀门勤更换
Four, check and reverse valve frequently change
如果已经把副烟道拆除，或是需要防止倒烟的效果更好，那么使用烟道止逆阀。一般情况下，油烟机的止逆阀效果不是很明显，而在烟道安装止逆阀可以保护油烟机，使烟道里的烟不会向管道和抽油烟机内倒灌。不过，安装止逆阀后要定期清洗，否则会使止逆阀呈打开状态，失去效果，而且烟道止逆阀好两年左右就更换一次。
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.
