You have determined that the hood of your next project will require a rating of at least 800 cubic feet per minute. (22.7 cubic meters per minute). To prevent "backdrafting" you suggest which one of the following?
Correct Answer
D. Provide a dedicated source for "make-up" air.
Explanation
To prevent backdrafting, it is necessary to provide a dedicated source for "make-up" air. This means that in addition to the exhaust air being removed by the hood, fresh air needs to be supplied to the space to maintain proper air circulation.
