副烟道务必保留
The auxiliary flue must be preserved
每个家庭的厨房都有烟道，并且烟道有主副区别，主烟道连接整个楼体，而副烟道是比较独立的。通常家中的油烟会先到副烟道中，接着再由隔板中的孔进去主烟道，这样可确保每户的油烟是隔开的。而如果把副烟道直接连主烟道，便会因为压力太低而造成倒烟串烟等现象。
Each family's kitchen has a flue, and the flue has a main and secondary distinction. The main flue connects the entire building, while the secondary flue is relatively independent. Usually, the cooking fumes in the home will first enter the secondary flue, and then enter the main flue through the holes in the partition, ensuring that the cooking fumes in each household are separated. If the secondary flue is directly connected to the main flue, it will cause phenomena such as inverted smoke and string smoke due to low pressure.
施工细节要注意
Pay attention to construction details
，决定油烟机安置的位置尤为重要。管道短较好。部分用户会为了美观， 将管道拉得更长，如此一来，关闭油烟机后，管道中还会集聚许多油烟排不出去，再倒回室内。此外，为了不破坏原主副烟道，其开口方位并非随意更改的，必须打到副烟道当中。
Firstly, it is particularly important to determine the location of the range hood. Short pipelines are better. Some users may pull the pipeline longer for the sake of aesthetics. In this way, after turning off the range hood, many oil fumes will accumulate in the pipeline that cannot be discharged and then return to the indoor environment. In addition, in order not to damage the original main and auxiliary flue, the opening direction is not arbitrarily changed and must be inserted into the middle of the auxiliary flue.
窗户排烟注意
Window smoke exhaust, pay attention to safety
部分用户为了防止串烟问题，舍弃原有烟道，直接在窗户开孔排烟，这样做也行，但有几点要留意，在窗户或墙体开洞前，必须通过物业的同意。其次应留意问题，通常排烟管尾端为金属材质，若开洞过小，金属传热或许会造成玻璃炸裂，且烟管通向窗外，强风对着吹会造成油烟倒灌。尽量把管道伸出后将管道往下窝，这样还能防止下雨时雨水流入管道，并将风挡在外面。
Some users, in order to prevent smoke issues, abandon the original flue and directly open holes in the window for smoke exhaust. This is also possible, but there are several points to note: first, before opening holes in the window or wall, the property management must obtain approval. Secondly, attention should be paid to safety issues. Usually, the tail end of the smoke exhaust pipe is made of metal material. If the hole is too small, the metal heat transfer may cause the glass to crack, and the smoke pipe leads out of the window. Strong winds blowing against it can cause oil smoke to pour back. Try to extend the pipeline and nest it down as much as possible, which can also prevent rainwater from flowing into the pipeline during rain and keep the wind out.
止逆阀门勤更换
Frequent replacement of check valves
若已将副烟道拆掉，或要避免倒烟的作用好，那么利用烟道止逆阀。通常状况下，止逆阀效果并非明显，而在烟道加装止逆阀能保护油烟机，让烟道中的烟不会往管道和油烟机中倒灌。但是，加装止逆阀后应定期清洁，不然会让止逆阀呈打开状态，失去效果，且好2年左右换一次。
If the auxiliary flue has been removed or if the effect of pouring smoke is to be avoided, then use the flue check valve. Under normal circumstances, the effect of a check valve is not significant, but installing a check valve in the flue can protect the range hood and prevent smoke from flowing back into the pipeline and range hood. However, after installing a check valve, it should be cleaned regularly, otherwise it will leave the check valve in an open state and lose its effectiveness, and it should be replaced every two years or so.
