Can I open the smoke crossing after the integrated ceiling is finished? What should I pay attention to?

The ceiling near the flue needs to be removed. The integrated ceiling can be removed with suction cups. Suction cups can be purchased from integrated ceiling merchants. Punch holes according to the needs of your own cigarette machine. Generally, the diameter of flue hole is 16- 18 cm, and it needs to be above the ceiling by 20 cm. Do not drive in the main flue. If you don't know, you can ask the property or ask the neighbors in the same apartment in the building. After opening the hole, the cut place of the aluminum gusset plate should be protected to avoid cutting and scratching the integrated ceiling of the pipeline kitchen. The reason is that the bathroom and kitchen have different degrees of humidity and odor.

The ventilation fan duct can lead to the ventilation shaft. It should be noted that the check valve should be installed correctly to prevent the odor in the ventilation shaft from flowing back to the room. If it is used in the kitchen, bathroom and other places where there is more moisture and lampblack, it must be installed. Before fixing the triangular keel, adjust the keel spacing to 300mm. Arrange the air outlet pipe of the range hood in front of the pinch plate. If you don't have a range hood, you don't need it Control the spacing of the first row of gusset plates, so that the spacing of gusset plates is 0, the four corners are cruciform, and the height of gusset plates should be consistent.

Next, open the junction box, connect it according to the corresponding function according to the wiring label, then install a switch to test whether it is electrified, and cover the junction box after it is electrified. Although the current home improvement is almost always handled by professional decoration masters, it is also very helpful if you know a little. Leave 3 control lines for kitchen lighting lines; When the kitchen is long, you can put a wire at each end to install a lamp, and three wires can meet the requirements of installing a ventilator or a window on the wall of the electric fan. We often encounter this situation when installing. All the tiles have been pasted, and the tiles are just 4-5 cm above the window, so the bricklayer will not mend the tiles. According to the specifications of the aluminum gusset plate, then fix the auxiliary keel with a special card. And ensure that there is no gap between the cutting angles.
