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 household has a flue in the kitchen, and there are main and auxiliary points in the flue. The main flue runs through the building, while the auxiliary flue is relatively independent. Generally, the lampblack in the family will go to the auxiliary flue first, then enter the main flue through the hole on the clapboard, so that the smoke and fume of every 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。一些合肥排烟管道业主会为了美观，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 of all, choosing the location of hood is very important. The shorter the better the pipe. Some Hefei smoke pipeline owners will pull the pipeline longer for the sake of beauty, so that after closing the oil smoke machine, the pipe will gather a lot of oil smoke and do not go out and back to the room. In addition, in order not to destroy the original main and auxiliary flue, its opening direction is not optional, it must be played 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。
In order to avoid smoking problems, some owners abandon the original flue and smoke directly through the windows. This is acceptable, but there are several points to note.
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 of all, before the window or wall surface opening must be approved by the property; secondly, attention to safety issues, the end of the general exhaust pipe is metal material, if the opening of the hole is too small, metal heat transfer may blow up the glass, injury to pedestrians, and smoke pipe to the window, strong north wind will lead to oil fume inversion. It is better to put the pipe out and pipe down, so that it can avoid rain and water into the pipeline when it rains, and put the windshield outside.

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. In general, the effect of the control valve is not very obvious, and the installation of the counter valve in the flue can protect the oil fume machine, so that the smoke in the flue will not be poured into the pipe and the smoke pump. However, the installation of the counter valve should be cleaned regularly, otherwise the reverse valve will be open, the effect is lost, and the best replacement of the pipe check valve is about two years.
