Installation of exhaust pipe of lampblack machine:

　　安装方法，将香蕉视频下载网址管一头插入止回阀出风口内外圈之间槽口，用螺钉紧固。另一头直接通过预留孔伸入室外。如香蕉视频下载网址管是通入公用烟道，一定要用公用烟道防回烟止回阀连接，并密封好。若香蕉视频下载网址到墙外，则建议在香蕉视频下载网址管外装上百叶窗，避免回灌。香蕉视频下载网址香蕉视频黄版APP一般直径15公分和18公分，但现在市场流行的都是15公分。洞口留小再扩充很方便，留大了要改小也不难，但万一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.

　　香蕉视频软件需要检查油烟香蕉视频黄版APP口是否有吊顶下移从而在上部所预留的空间和位置的条件。在预埋香蕉视频下载网址管时注意封闭住烟道口的缝隙，并保证其牢固不脱落。吊顶之前将烟机香蕉视频下载网址管预埋进吊顶上部，需要根据橱柜的设计图纸来确定香蕉视频下载网址管在吊顶上外露口的位置，需要参照的还有烟机的款式，一般说欧式烟机的香蕉视频黄版APP是在中间位置，而中士烟机的香蕉视频下载网址管口却在烟机的一侧。若香蕉视频下载网址到共用烟道，勿将香蕉视频下载网址管插入过深导致香蕉视频下载网址阻力增大。若是通向室外，则务必使香蕉视频下载网址管口伸出75px。香蕉视频下载网址管伸出户外或通进公用吸冷风烟道，接口处要严密，不允许将废气排到热的烟道中。抽油烟机香蕉视频黄版APP越短越好，如果把香蕉视频黄版APP拉得比较长，这样一来，关掉油烟机后，香蕉视频黄版APP里还会集聚很多油烟排不出去，再倒回室内。

　　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.

　　Installation requirements of exhaust pipe:

　　排风出口到机体的距离不宜过长，转弯半径尽可能大且少转弯，否则影响香蕉视频下载网址效果。香蕉视频下载网址管伸出户外或通进共用吸冷风烟道，接口处要严密，不需将废气排到热的烟道中。出风管不宜太长，好不要超过2米，而且尽量减少折弯，避免多个90度折弯，否则会影响吸油烟效果。

　　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.
