The PVC plastic coating material has passed thousands of hours of accelerated salt spray, humidity cabinet, and water immersion tests with no loss of adhesion or corrosion resistance. It resists corrosion from concrete and corrosion from minerals and salts found in normal backfill materials. Uni-Coat duct and fittings enable you to install high- performance underground airflowsystems. All components are machine -formed to ensure uniform size, construction, and performance. Standard Uni-Coat duct and fittings have a single -wall, round design. Standard diameters of S through 60 inches are available. We also offer double -wall, insulated round duct and fittings. Uni-Coat Duct All Uni-Coat spiral duct is manufactured with a lockseam construction that adds strength and rigidity to the duct while maintaining a smooth interior to reduce friction. For underground and concrete -encased underground installations of duct 14 inches in diameter or larger, Uni-Coat duct is constructed with a double corrugation between the lockseams to further increase strength and rigidity.

Trenches must be pitched to prevent the buildup of water around the ductwork. 2. Appropriate girth angle structural reinforcement must be installed on the ductwork. Such reinforcement should be designed by a structural engineer based on local conditions. 3. Ductwork encased in concrete must be tied down to avoid floating during pouring. 4. Fill or concrete must not be poured directly onto the ductwork. It should be poured in successive layers and tamped firmly around the ductwork. Pouring fill or concrete directly onto the ductwork will cause denting or collapse. 5, Vapor barriers must always be used between the ductwork and the fill or concrete. 6. Ductwork must always be buried above the water table. 7. Use the metal thicknesses listed in McGill AirFlow's specifications for underground ductwork. 8. Water -based duct sealants should never be used in underground applications. 9. Use the following load specifications: (Refer to McGill AirFlow's Engineering Report No. 155 for conditions other than those listed.)

Fittings with a standing seam construction have been tested and shown to outperform solid -welded fittings. Forthe remaining diameters of elbows (31 through 60 inches), and for all diameters of other Uni-Coat fittings, the seam is riveted and sealed, button punched and sealed, or fastened with stainless steel sheet metal screws and sealed. The sealing material is McGill AlrSeal's Uni-Coat'"° Duct Sealer.

Although duct as large as 60 inches in diameter has been used successfully in underground systems, it should be installed only by contractors experienced in this application. For any diameter duct, metal thickness can be increased to a maximum of IS gauge. Angle rings or other bracing can be added for additional reinforcement. All external reinforcement should be primed and coated with Uni-Coat paint. Under -Slab, Above Grade The duct, either encased in concrete or buried directly below a concrete slab, is installed above the original line of undisturbed soil and above the watertable. Encasing the duct in concrete with a porous flll beneath It is the best way to install Uni-Coat duct, An appropriate vapor barrier (e.g., 4 mll polyethylene) must be placed between the duct and the concrete.

A 2 1/2-inch minimum thickness concrete slab should be placed over the duct, with the top of the duct, near the bottom of the slab. A vapor barrier must also be placed between the slab and the fill. Under -Slab, Below Grade The duct, either encased in concrete or buried directly below a concrete slab, is installed belowthe original grade, but safely above the water table. This installation requires that the duct be buried in a trench with porous fill and an appropriate vapor barrier. The first 12 inches of fill must be carefully shoveled on top of the duct. The fill must not be dumped or shoved directly into the trench and must not contain stones larger than 2 inches in diameter. Once the duct is properly covered, the fill must be firmly tamped under and around the duct, but must not be heavily impacted. Light equipment such as small bulldozers or backhoes must not be operated near the area until there is at least 2 1/2 feet of compacted cover. www.mogillairflow.conVteADocs/un!Coat/uc—install.htm 214 �EWPORT CITY OF NEWPORT BEACH O� b ta FINANCE DEPARTMENT U'r 3300 NEWPORT BLVD.
