This is an architectural specification document for kitchen hood exhaust systems for the Puerto Rico Army National Guard facility 22A-2.

The specification establishes requirements for cook serving and cook food preparation hoods, with detailed performance standards including exhaust air supply balance, duct air flow velocity requirements (1500-2200 FPM), and makeup air provisions. Two hood configurations are specified: EF-7 (Cook Serving) measuring 1'6" × 3'0" × 3'0" and EF-8 (Cook Food Prep) measuring 2'6" × 4'0" × 3'0". Equipment requirements include exhaust air (CFM) of 2,400 and 6,500 respectively, makeup air (CFM), exhaust stacks at 1.125", and various components such as UL-classified aluminum or stainless steel baffle-type filters, UL-listed and approved vapor-proof noncandescent light fixtures, dishwasher connections, and fire suppression systems. All hoods shall be fabricated in accordance with NFPA Bulletin #96 and UL 710 standards. Hoods must be supported and earthquake-braced per International Building Code (IBC) and International Mechanical Code (IMC) 2009. The specification requires horizontal exhaust ducts with appropriate slope (minimum 1/8" per 10 linear feet toward exhaust hood) and vertical exhaust ducts with minimum 1/4" slope toward exhaust hood. Banding requirements specify 304 stainless steel bands with maximum 1-1/2" spacing from the lowest edge and centered spacing thereafter. Installation shall be performed by the contractor per manufacturer recommendations.
