The minimum distance between a gas cooktop and a range hood can vary based on local building codes and regulations, as well as the specific manufacturer's guidelines for the cooktop and range hood you are using. It's essential to check the installation manual provided by the manufacturer for your specific cooktop and range hood to determine the exact minimum clearance requirements.
In general, to ensure safe and efficient operation, a common guideline is to maintain a minimum distance of at least 24 inches (approximately 61 centimeters) between the top of the gas cooktop and the bottom of the range hood. However, this distance may vary depending on factors like the type of cooking surface, the hood's power and design, and any local regulations.
To reiterate, always consult the installation manuals of both the gas cooktop and range hood you have or plan to purchase. If you are unsure about the installation requirements, it's best to reach out to a professional installer or consult your local building codes to ensure compliance with safety regulations. Safety should always be a top priority when dealing with gas appliances.
