The FVs ar constructed of ABS plastic which serves as the FV's h, °using, and a front grill that contains an anodized metal creen imbedded in polypropylene plastic. On contact l�ith rising flood water, the grill will disengage from its sec ed position, allowing flood water and debris to flow throug in either direction. The FVs are available in two series s described in Section 3.3. ESR-3560 Reissued September 2097 This report is subject to renewal September 2oia A Subsidiary of the Intemational Code Council The sealed series models contain two rubber flaps that Close the _ FV to the passage of air when using with conditioned areas or sealed crawl spaces. In the same manner as the grill, the two rubber flaps -are pushed open by water pressure, allowing water and debris to flow through the FV in either direction. See Figure 1 for an illustration of the Flood Flaps® automatic FV. 3.2 Engineered Opening: The Flood Flaps® automatic FVs comply with the design principle noted in Sections 2.7.2.2 and 2.7.3 of ASCE/SEI 24-14 [Section 2.6.2.2 of ASCE/SEI 24-05 (2012 and 2009 IBC and IRC)] for a rate of rise and fall of 5 feet per hour (0.423 mm/s). In order to comply with the engineered opening requirement of ASCE/SEI 24, Flood Flaps® automatic FVs must be installed in accordance with Section 4.0. 3.3 Flood Vent Series Models: Flood Flaps° automatic FVs are available in two series with multiple models and sizes as described in Table 1. The sealed series models, designated FFWF, include two rubber flaps for the prevention of air flow. The multi- purpose series, designated FFNF, omits the rubber flaps. 3.4. Natural Ventilation: Flood Flaps®- automatic FV models FFNF12, FFNF08, FFNF05, and FFNF02 have metal screens with 1/4 inch by 1/4 inch (6 mm bV 6 mm) openings and provide 37 square inches (0.02 m2). of net free opening to supply natural ventilation for under -floor ventilation. Flood Flaps® automatic FV models FF1NF12, FFWF08, and FFWF05 have not been evaluated for use as openings for under- floor ventilation. 4.0 DESIGN AND INSTALLATION Flood Flaps® automatic FVs are designed to be installed into walls of existing or new construction. Installation of the FVs must be in accordance with the manufacturer's Instructions, the applicable code and this report Flood Flaps® automatic FVs can be installed in wood, masonry and concrete walls up to a thickness of 12 inches (305 mm). In order to comply with the engineered opening design principle noted in Sections 2.7.2.2 and 2.7.3 of ASCEISEI 24-14 [Section 2.6.2.2 of ASCE/SEI 24-05 (2012 and 2009 IBC and IRC)], the Flood Flaps® FVs must be installed as follows: ■ With a minimum of two openings on different sides of each enclosed area. !CC -ESE tion Reports are not to be construed as representing aesthetics or any other attributes not specically addressed, nor are they to be construed as an endo meet afthesubjed ofthe report or a recommendation for its use.
