There needs to be information provided in written form that indicates the proposed method(s) of providing the minimum 1600 CFM exhaust and the equivalent amount of tempered makeup air. The original submittal indicated a 1600 CFM Type I hood/exhaust fan and a 720 CFM makeup air unit from EconAir. I informed you that additional makeup air was required so that provided would be approximately equal to the amount of exhaust per IMC 508.1. The options of adding a ducted gravity opening with a duct heater or to upsize/add to the originally proposed 720 CFM was mentioned by me at that time. I later received from you a specification sheet from CaptiveAire that proposed a 900 CFM fan serving the hood along with a 900 CFM makeup air unit. While the amount of makeup air is now equivalent to that of the exhaust, the amount of exhaust air provided by the CaptiveAire unit does not meet the minimum required per IMC 507.5.2. To clarify, I made comments on the specification sheet (see attached) asking if only the CaptiveAire makeup air unit was to be installed, or was it being added to the originally proposed EconAir unit. I also asked if the exhaust fan noted on the specification sheet was to be installed instead of the originally proposed EconAir unit. To date, the submitted information (each part or as a whole) does not clearly indicate how the minimum required 1600 CFM exhaust and the equivalent amount of tempered makeup air will be provided.

Thanks - Anthony (Maize and Barley) On Thu, Dec 6, 2018 at 10:03 AM Miller, Chuck <Chuck.Miller(&,edmondswa.gov> wrote: Can you call me when you get a chance? The proposed size of the makeup air fan is quite a bit low —it doesn't comply with International Mechanical Code (IMC) 508.1. While it's pretty common to slightly undersize the makeup air to ensure `capture and containment' at the hood, typically nothing more than 10% is acceptable.
