Unfortunately, chimney hoods are a European creation, and typically kitchens across the pond do not have professional ranges. Thus, they are only 19-21 inches deep, which is too shallow for properly venting a professional range.
Their only choice is a BEST K4236. Best is 24 inches deep and 1100 CFM.
Small tip for proper ventilation:
1. Decent motor. Measurement is CFM or cubic foot per minute (how many cubes of air are passed through the hood in 1 minute)
2. Capture area. In a pro application, minimum 24 inches depth.
3. Duct Run: Straight runs are measurably better as bending duct decreases efficiency.
4. Duct Size: Minimum 6 inch round...The larger vents require 8-10 inch round.
