Hello. Please help with the ventilation device - you bought a dome hood over a gas stove, there is an exhaust ventilation duct in the wall and a hood - a pipe on the roof (sandbox) near AOGV. The plate is located on another wall, i.e. it’s not beautiful to stretch through the entire kitchen (4 x 4m), we want to punch a hole in the wall near the window and above the stove and I have a question - is it necessary to put a forced valve on the exhaust pipe? If it is not installed, will cold air enter from the street through the hood when it does not work? And the ventilation is a window (a wooden frame) and if you open the window. For earlier, I am very grateful for the answer.
Hello! The valve is definitely needed! Or your apartment will be fresh, especially in the winter.
But seriously, now during the repair all this is laid down in the project and, as a rule, the entire hood is hidden behind a headset or design ideas. To break through the wall is also an option, but, firstly, you need a valve. Without it, all the cold will go into the apartment and it will be very cold. Secondly, the valve always makes noise. Mechanical periodic movements during its operation \ bleed.
Therefore, we would recommend to conduct the channel as it should in a hood, but there is also a variant with a valve.
