Joint assembly utilizes a flange & sleeve joint connection for diameters 150 to 300 mm (6 to 24 inches). Joint assembly utilizes flanged mating surfaces for diameters 660 to 900 mm (26 to 36 inches). Manufacturer approved sealant will be used on the flange surface. Flanges are joined with a V-band secured by tightening draw bolts. Manufacturer approved sealant will be applied to the channel of the V-band prior to installation. Utilize a manufacturer approved snap-lock gasket connection for diameters 75 to 125 mm (3 to 5 inches). For double wall vents, where exposed to weather, the outer closure band shall be sealed to prevent moisture from entering the space between the walls. All parts exposed to the weather shall be protected by one (1) coat of corrosion and heat resistant base primer and one (1) coat of heat resistant paint unless constructed of 430, 304 or 316 stainless steel. Vent shall terminate in accordance with installation instructions and local codes. STARTUP AND TESTING Perform tests as recommended by product manufacturer and listed standards and under actual or simulated operating conditions and prove full compliance with design and specified requirements. Tests of the various items of equipment shall be performed simultaneously with the system of which each item is an integral part. When any defects are detected, correct defects and repeat test at no additional cost or time to the Government. //The Commissioning will observe startup and contractor testing of selected equipment. Coordinate the startup and contractor testing schedules with COR and Commissioning Agent. Provide a minimum notice of 10 working days prior to startup and testing.// //COMMISSIONING Provide commissioning documentation in accordance with the requirements of Section 23 08 00, COMMISSIONING OF HVAC SYSTEMS. Components provided this section of the specification will be tested as part of a larger system.// DEMONSTRATION AND TRAINING Provide services of manufacturer’s technical representative for //4// // // hour//s// to instruct each VA personnel responsible in operation and maintenance of the system.
