First: Fire safety hazard
The kitchen flue belongs to the public flue of commercial housing, a large number of kitchen lampblack is discharged into the kitchen flue, attached to the wall of the brick chimney, if the fireplace chimney is installed inside, because the fireplace chimney itself is high temperature, is bound to produce fire and other safety hazards.
So when the fireplace chimney walks into the kitchen flue, it's not just about you, it's about the whole building!
Second: the use of the kitchen chimney
We know that the diameter of the general kitchen flue is 400*400mm, and the fireplace chimney can not be directly into the kitchen flue, need special caliber of stainless steel chimney through it.
The diameter of single-layer chimney of fireplace is generally 150mm, while that of double-layer chimney is 200mm. Imagine that a pipe with a diameter of 200mm is put into the chimney of 400x400mm, and the remaining space will have what kind of influence on the kitchen of the whole building, which can produce lampblack pouring, anti-smell and other problems, affecting the normal life of neighbors!
Third, installation standards
According to European standards, the vertical height and horizontal displacement of real fire chimney have strict industry standards when it is installed, and the horizontal displacement of fireplace shall not exceed 20% of the vertical height.
In the actual installation, the fireplace will generally be installed in the living room position, from the fireplace installation position, let the chimney into the kitchen flue, its horizontal displacement and direction will not meet the installation standard!
Fourth: high cost, low cost performance
Tall building does not suit to install fireplace to still have a reason is chimney installation cost is high, it is installation cost is high, but chimney cost is high!
For example, if your whole building is 25 stories high, and you are on the 10th floor, the installation must be completed by Spiderman, and the labor cost is high. Secondly, the chimney cost of your building from the top floor to the top floor is nearly 50 meters high, which is also unacceptable!
