How to renovate the kitchen flue?

From the perspective of the building structure design, the flue cannot be changed laterally because it is divided into main and auxiliary flues. Otherwise, it will affect the smoke exhaust and may cause backflow. For the sake of appearance, the flue mouth should be moved up and down. There will be no adverse effects. First of all, look at the form of the hood. If it is a Western-style hood (mostly pyramid-shaped), the general direction of the flue is vertically upward, plus a stainless steel flue decorative plate. The flue opening can be changed into the ceiling. I remind you that if it is a Chinese-style hood, There is generally no decorative plate outside the flue duct, so the flue opening needs to be moved to a suitable position under the suspended ceiling so that the flue duct can be connected to the hood through the decorative plate or from the hood wall cabinet.
