1 BUILDING MATERIALS EVALUATION COMMISSION (BMEC) CONSOLIDATED AUTHORIZATION REPORT DATE OF AUTHORIZATION February 26, 1998 BMEC REFERENCE BMEC # A BMEC APPLICATION # BMEC A * Denotes a new or amended clause Amended August 27, 1998 STUDOR Air Admittance Valve (Mini-Vent and Maxi-Vent) 1. Applicant Studor Inc Main Street DUNEDIN, Florida Manufacturing Facilities Mini-Vent D-Rep Plastics, Inc A 53rd Street North CLEARWATER, Florida Maxi-Vent MPC-D G Plastics Steenweg Op Mol 177 B2300 TURNHOUT, Belgium Recess Box: Midtech, Inc. of America 924 West First Street MCPHERSON, Kansas Description Studor Air Admittance Valve (AAV) is intended for use as an alternative measure to a vent pipe that extends to the open air. These valves open under a negative pressure within the drainage system allowing air to enter the venting system to maintain trap seals. The valves close by gravity under no pressure differential (no flow) or under positive pressure to prevent the leakage of sewer gases through the valve. The Studor AAV comes in two models, the Mini-Vent which will accommodate 1 ¼" and 1½" pipe sizes, and the Maxi-Vent which will accommodate 2", 3" and 4" pipe sizes. 4. Authorization Requested The applicant sought authorization for the use of their product as an alternative to extending a vent pipe to open air as presently required by the OBC. 5. Assessment Reports and assessments provided by the applicant show that if the Studor AAV's are designed, performance tested and maintained in accordance with the limitations

2 2 the manufacturer's instructions and conditions stated in this authorization, the level of the performance required bythe Ontario Building Code for individual venting, duel venting, wet venting or circuit venting for fixtures located on the same floor level will be provided. Reports submitted and reviewed: 1. United States Testing Company Inc. Report # TS dated 9/10/93 Evaluation of Studor Air Admittance Valves for Compliance with ASSE United States Testing Company Inc. Report #TS R revised date 2/13/95 Testing of Studor Air Admittance Valves as type A and Type B in accordance with ANSI/ASSE SGS United States Testing Company Inc. Report #TS R dated 5/17/96 Evaluation of Studor Air Admittance Valves to ANSI/ASSE Research Report #92-46, Boca Evaluation Services Inc. Studor Mini-Vents and Maxi-Vent Air Admittance Valve dated January Engineering Reports dated November 30/92, December 15, 1992 and June 1, 1994 prepared by J.B. Engineering and Code Consulting, P.C. 6. Authorization Since these reports include figures (1 through 13) and illustrate piping arrangements in plumbing systems that could comply withdifferent Plumbing Codes in the United States and not in compliance with venting requirements in the Ontario Building Code Part 7, Section 7.5 the figures shall not be used as an approved piping arrangement and articles ; ; ; , and this authorization must govern the location and the sizes of the Studor Air Admittance Valve * The use of Studor Mini-Vent AAV's sizes 1¼" and 1½", and Maxi-Vent AAV's sizes 2", 3" and 4" is authorized for use within a plumbing system as an alternative where there is no other reasonable means of connecting to the traditional venting system and where there is no danger of back pressure presenting a problem.

3 3 A. SPECIFIC TERMS AND CONDITIONS: 1) Vent system utilizingstudor AAV shall conform to performance standards for "Fixture and Branch Air Admittance Valves" ANSI/ASSE 1051/90 (rev. 1996). * 2) All PVC and ABS materials used in the Studor AAV shall conform to ASTM D and ASTM 2661, respectively. 3) The Studor AAV shall be installed in accordance with the manufacturer's installation instructions. In case of a conflict between the manufacturer's installation instructions and the Ontario Building Code requirements, the provisions of the Code shall govern. 4) The manufacturer shall supply instructions on the proper and safe installation of the AAV. Such instructions shall include detail drawings and must remain on site. 5) The documents submitted for permit approval shall contain the design and layout of the entire drainage and venting systems. This includes, but not limited to plan views, riser diagrams, all pipe sizes, fixture units and information on the locations and sizes of all Studor AAV's. 6) The AAV shall be installed after the drain waste and vents (DWV) have been tested as required by articles and/or and prior to the final test as required in article so as to establish that an adequate seal under positive pressure is achieved. 7) Individual, dual, wet and circuit vents shall be permitted to terminate with a connection to a Studor AAV. When more than three fixtures connect to the horizontal branch a relief vent is required. 8) The AAV shall not be used on a vent stack or stack vent. 9) When the Studor AAV is used on a 4" vent the inner lip of the gasket must be cut off. 10) The AAV shall only vent fixtures that are located on the same floor level and connect to a horizontal branch line. 11) The horizontal branch drain shall connect to the building drain or the stack not more than 4 stories (as defined in Part 7) from the top of the stack. 12) The horizontal branch that is circuit vented shall be provided with a relief vent that shall connect to a vent stack, stack vent, header or extend outdoors to open air. 13) Studor AAV's cannot be used as relief vents.

4 4 14) The relief vent shall connect to the horizontal branch drain between the stack or building drain and the most downstream fixture drain connected to the horizontal branch drain. The relief vent shall be sized in accordance with section of the O.B.C. The relief vent may be a wet vent if it is 2" size or greater and not more than one fixture having a maximum of 1½ fixture units is drained into it. 15) The AAV shall be located 6" (150 mm) above the flood level rim of the fixture being vented where possible, and in case of a single fixture, as high as possible but not less than 4" (100 mm) above the weir of the fixture trap. 16) The AAV shall be located within the maximum developed length permitted as per article O.B.C. 17) The AAV shall be located in an area that is accessible for inspection, service, repair and/or replacement. For the purpose of this approval, concealment in walls and/or floor spaces without removable grills or access panels is not considered accessible. 18) The AAV shall not be located in an attic space. 19) The AAV shall be located within a ventilated space that allows air to enter the valve. 20) The AAV shall be rated for the size of the vent to which the valve is connected. The Mini-Vents sized 1¼" and 1½" shall be installed on vent pipes of 1¼" and 1½" nominal sizes. The Maxi-Vents sizes 2", 3" and 4" shall be installed on vent pipes of 2", 3" and 4" nominal pipe sizes. 21) Each plumbing system shall have a minimum of one 3" stack which shall be extended outdoors to the open air as per sentence (2) O.B.C. 22) AAV shall not be used for corrosive or acid waste systems, grease and oil interceptors installations or any other special waste systems. 23) The AAV shall not be used for any closed system such as a sewage ejector, or a manhole located inside the building. 24) The AAV shall not be located in spaces utilized as supply or return air plenums. 25) When the AAV is located in an area where freezing conditions may occur protection of the AAV shall be done in accordance with the manufacturers installation instructions. 26) A label of 2" x 2" (50mm x 50mm) in size shall be placed on hydro panel, stating the following: "These premises have an air admittance valve installed

5 5 in the Plumbing System". 27) This authorization is based on O.B.C. Part 7 requirements. All matters relating to combustible construction requirements apply as per Part 3 of the O.B.C. 28) The AAV must be installed as close to true vertical as possible, but not more than 15 o off the true vertical.
