when installing the flue of the range hood, the auxiliary flue must be reserved, because the auxiliary flue is relatively independent, and the oil fume at home goes to the auxiliary flue first, and then enters the main flue. If the auxiliary flue is directly connected to the main flue, there will be smoke cross-talk or smoke back, which will affect the function of the range hood. Next, Xiaobian will specifically introduce the installation method of the range hood flue and the price of the range hood.

installation method of flue of range hood

1. Single flue type, which is a simple rectangular flue pipe. When installing, the rectangular flue pipe should pass straight through each floor of the residence, and then an air inlet connected with the range hood is reserved in each floor of the residence. In this way, the smoke of each layer will be discharged into the flue under the promotion of the range hood, and then the smoke will be discharged at the air outlet.

2. Primary and secondary type, this flue is composed of two kinds of rectangular smoke pipes side by side. When installing, these smoke pipes should go straight through each floor, and then the flue should be provided with an air inlet connected with the fume exhauster in the residence of each floor. The main flue and the secondary flue will meet at a certain interval from the air inlet, and there will be an air inlet at the bottom of the main flue. When it works, the range hood will discharge smoke into the secondary flue, and then the buoyancy and the propulsion of the range hood at the temperature of the smoke will raise the smoke for a period of time before entering the main flue for discharge.

3. Variable pressure type, which is to make the flue of each floor into different cross sections. After this change, the airflow will be discharged upward according to the movement law of flue gas.

4. check valve type. The installation of this flue is to configure a range hood interface and a check valve at the air inlet of each layer on the single-tube flue, so as to prevent the air flow from going backwards and the lampblack will move to the flue in one direction.

Precautions for the installation of kitchen flue

1. When installing kitchen flue, you must keep the auxiliary flue, because the auxiliary flue is relatively independent, and the oil fume at home goes to the auxiliary flue first, and then enters the main flue. If the auxiliary flue is directly connected to the main flue, there will be smoke string or smoke inversion.

2. Pay attention to the construction details when installing the kitchen flue. During installation, it is suggested that the shorter the smoke duct, the better. Don't lengthen the pipe for the sake of beauty, so it is practical to turn off the range hood and there will be soot gathering, which will flow back indoors.

3. Try not to give up the original flue when installing the kitchen flue. Although you can open a hole in the window to smoke, if the end of the smoke exhaust pipe is made of metal and the hole is too small, the glass will burst after the metal conducts heat, which will hurt people. Moreover, if the smoke pipe leads out of the window, there will be a phenomenon of oil fume backflow when there is strong wind.

4. In order to prevent the smoke in the flue from flowing back into the range hood and the pipeline, a check valve can be installed on the flue. But after installation, you must remember to clean it regularly and replace it regularly.
