Installing a commercial kitchen hood typically involves the following steps: The installer mounts the hood to the ceiling or wall, ensuring that it is securely fastened and level. Ductwork is then installed to transport air from the hood to the outside of the building. This may require cutting holes in walls or ceilings, depending on the layout of the kitchen. The hood is connected to the ventilation system, which may include fans, makeup air units, and fire suppression systems. The installer tests the hood and ventilation system to ensure proper operation and compliance with local building codes and health regulations.
