1、 How to install smoke exhaust pipes

1. Single flue type, this is a type of rectangular smoke pipe that passes straight through each floor of the residence, and then reserves an air inlet connecting to the range hood in the room.

2. Variable pressure type, making each layer of flue into different cross-sectional styles, and during smoke exhaust, the airflow is discharged upwards.

3. Check valve type, it is installed at the inlet and outlet of each layer on the single flue, with a range hood interface and a check valve, which can prevent the airflow from reversing.

2、 What are the precautions for installing exhaust ducts

1. Choosing the appropriate installation location is crucial, and the position of the flue is generally as short as possible. This makes it look more beautiful and ensures that the oil fumes can be discharged cleanly.

2. A prescription will be equipped with a flue, and the flue also has a primary and secondary distinction. The main flue is connected to the building, while the secondary flue is a single one. Generally, smoke from the home will first enter the secondary flue, and then use the small hole on the partition to reach the main flue. Therefore, it is important to ensure that the secondary flue is installed normally, otherwise there will be smoke return and smoke linkage.

3. There is a lot of oil fume in the kitchen, so it is equipped with exhaust ducts that must be cleaned at regular intervals. Otherwise, over time, the accumulation of oil fume will cause the pipes and range hood to backflow. The check valve in the normal exhaust duct needs to be replaced every two yuan.

4. Many people, in order to avoid smoking, will open holes on the windows. During construction, attention should be paid to opening holes, which must be approved by the property management and ensure safety. Due to the metal heat transfer at the end of the smoke exhaust pipe, which is made of metal, it may cause glass to burst and endanger people's safety. Therefore, when installing, the smoke exhaust pipe should be led outside the window.
