　　安装方法，将91视频网站观看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91视频网站观看管是通入公用烟道，一定要用公用烟道防回烟止回阀连接，并密封好。若91视频网站观看到墙外，则建议在91视频网站观看管外装上百叶窗，避免回灌。91视频网站观看91视频成人网站一般直径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.

　　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.
