The installation position of the exhaust hood in Jinan hotel kitchen is closely related to the length of the pipe. Many family owners for aesthetic, will let the installation master will pull the pipe very long. In fact, in this way, it is easy to make the oil fumes in the pipeline can not be discharged.

然后，再进行安装通风管道。通风管道安装首先找好标高，用电钻打墙洞，配合预留的支架孔洞埋设吊托支架;将组装好的风管找平、找正，再用紧固螺栓固定。

Then, install the ventilation pipe. In the installation of ventilation pipe, the elevation shall be found first, the wall hole shall be drilled with electric drill, and the hanging support shall be embedded with the reserved support hole; the assembled air pipe shall be leveled and aligned, and then fixed with fastening bolts.

比较后，如果是通风排烟管道的安装，通风管道和排烟管道应该分开，两者的通风方向和地点是不同的，流通的空气质量前者优于后者，所以不能使用同一个管道。通风管一般有两种圆形和矩形，如果是圆形风管就按平均直径。

After comparison, if it is the installation of ventilation and smoke exhaust pipe, the ventilation pipe and smoke exhaust pipe should be separated. The ventilation direction and location of the two are different. The air quality of the former is better than that of the latter, so the same pipe cannot be used. There are generally two kinds of circular and rectangular ventilation pipes. If it is circular, the average diameter of the ventilation pipe is calculated.

二、极易发生火灾

2、 Fire prone

厨房的抽油烟脱排罩内及罩上的空压管道内积累油污后，在炒灶工作时， 炉头的火焰上飞，进入烟罩及排油烟管道内，极易引起罩内和管道内的油污燃烧，引发火灾。

When cooking, the flame at the end of the stove will fly up and enter into the hood and exhaust pipe, which will easily cause the oil burning in the hood and pipe and cause fire.
