1. The structure and material of the wall installed by kitchen smoke hood should have sufficient strength. The outer wall openings of smoke exhaust pipes and gas pipes can be made of prefabricated concrete blocks with holes or pre-embedded steel pipes with holes. Installation method of insulation wall (preferably hollow brick) and ordinary wall, if the wall is not strong enough, then use wood or other materials to reinforce.
2. The exhaust pipe installed in the kitchen exhaust hood directly passes through the outer wall to the outdoor. Components should be set at the outdoor exhaust outlet to prevent pollution and wind. The cross section of the vertical flue connecting with the ordinary vertical flue should be determined according to the calculation of emission.
3. The installation height of kitchen exhaust hood should be at least 65 cm above the gas stove, and 65-75 cm is suitable.
Cautions for installation of kitchen smoke hood: First, we need to check whether the ceiling on the kitchen smoke screen moves downward in order to preserve the upper space and location conditions.
2. When burying flue, pay attention to closing the flue gap to ensure that the flue is firm and does not fall off.
The upper limit will be the first 3 of the smoke machine, the smoke pipe embedded in the ceiling, need to determine the smoke pipe cabinet exposure position on the ceiling according to the design drawings, need to refer to the style of the smoke machine, generally speaking, the European smoke machine pipe is in the middle position, and the side of the smoke pipe of the sergeant smoke machine. These conditions affect the location of the retention opening.
4. If the kitchen is located on the side of the balcony, we need to pay attention to whether the lampblack pipeline passes through the lintel board of the building. In principle, the general property management departments are not allowed to drill through the lintel board flue. This treatment method can avoid the distance between kitchen exhaust chimney and wall, because the distance between kitchen exhaust chimney and wall is greater than the depth of suspension cabinet, affecting the installation of suspension cabinet, and can also avoid completion.
