What provisions must be made where vented fuel burning appliances are located in the same space as an exhaust hood?

In the scenario where vented fuel burning appliances are located in the same space as an exhaust hood, it's essential to ensure that the operation of the exhaust hood does not interfere with the proper ventilation of the fuel burning appliances. This is crucial because the exhaust hood is designed to remove air, heat, and fumes from cooking processes, which can create a vacuum or negative pressure in the room. If this negative pressure affects the appliance vents, it may cause potentially hazardous combustion gases to backdraft into the room or lead to improper functioning of the fuel burning appliances.

Thus, provisions must be made to prevent any interference with the appliance vents by ensuring that the systems work in tandem without compromising safety. This means either designing the exhaust systems to account for the presence of the fuel burning appliances or using mechanical means to maintain a balanced airflow that does not disrupt the venting process. By doing so, safety hazards are minimized, and the appliances can operate efficiently and safely within the shared space.
