D. Automatic Controls: Position automatic control valves for full flow through the heat

transfer equipment of the system during tests. E. Flow: Flow through by-pass circuits at three-way valves shall be adjusted to

balance that through the supply circuit. F. Distribution: Adjust distribution by means of balancing devices (cocks, valves, and

fittings) and automatic flow control valves. Do not use service valves for adjustment. Where automatic flow control valves are utilized in lieu of venturi tubes, record only the pressure drop across the valve if within the pressure drop rating on the valve tag.



G. Special Procedures: Where available, pump capacity (as designed) is less than total flow requirements of individual heat transfer units of system served, full flow may be simulated by the temporary restriction of flow to portions of the system.

PART 3 - EXECUTION 3.1 SURFACE CONDITIONS A. Inspection: 1. Prior to work of this Section, carefully inspect the installed work of other trades


2. Verify that the duct systems may be installed in accordance with pertinent

codes and regulations and the reviewed Submittals. 3.2 INSTALLATION OF DUCTWORK AND AIR DEVICES A. Provide and erect in accordance with the best practice of the trade ductwork shown

on the drawings and as required to complete the intended installation. Make offsets as shown or required to place ductwork in proper position to avoid conflicts with other work and to allow the application of insulation and finish painting to the satisfaction of the Architect. Sizes given are "inside - clear" dimensions and not necessarily that of sheet metal. Ducts shall be arranged to adjust to "field



conditions". The Sheet Metal trades shall coordinate his work with other trades. Work shall conform to ASHRAE duct construction recommendations, SMACNA "Duct Construction Standards", NFPA, and the requirements of the IBC code.

B. Joint Sealing: See PRODUCTS section. C. Longitudinal joints: See PRODUCTS section. D. Turns shall be made with long radius elbows or, if physically impossible to use long

radius elbows, shall be square turns with specified turning vanes. CAUTION: Turns not conforming to this requirement shall be ordered removed and replaced with properly built turns.

E. Access Doors: Provide access doors for concealed apparatus requiring service and

inspection in the duct system including but not limited to dampers, sensors and motors, and upstream and downstream from duct coils.

F. Duct Sleeves and Prepared Openings: Install duct sleeves and prepared openings

for duct mains, duct branches, and ducts passing through walls, roofs, and ceilings. Insure the proper size and location of sleeves and prepared openings. Allow one-inch clearance between duct and sleeve or one-inch clearance between insulation and sleeve for insulated ducts, except at grilles, registers, and diffusers.

G. Duct Supports: Unless otherwise indicated, provide one-inch wide by 16 gage

galvanized steel sheet metal strips on each side of ducts. Anchor risers in the center of the vertical run to allow ends or riser free vertical movements. Attach supports only to structural framing members. Do not anchor supports to metal decking unless a means is provided (architectural review required) for preventing the anchors from puncturing the metal decking. Where supports are required between structural framing members, provide suitable intermediate metal framing. Where C clamps are used, use retainer clips.

H. Flexible Collars and Connections: Provide flexible collars between fans and ducts

or casings and where ducts are of dissimilar metals, except where fans are internally connected to the casing with flexible connectors. For round ducts, securely fasten flexible connections using stainless steel clinch-type draw-band. Nylon drawbands may be used if installed using the drawband manufacturer's lever-action tightening tool. For rectangular ducts, lock flexible connections to metal collars. All air handling equipment fan connections to the duct systems shall have flexible connections, factory or field-installed.

I. Flexible Ducts: Provide where indicated. No fiberglass shall be exposed or in

contact with air flow. Flexible duct length shall not be more than 4'-0". Install with metal band hangers and without excess length, provide maximum extension of flex duct. Securely fasten flexible ducts to metal collars using a stainless steel or tool-tightened nylon drawband on the duct core and a second drawband on the insulation vapor barrier. If the duct exceeds 12 inches diameter, position the drawband behind a bead on the metal collar. Taping in lieu of drawbands is not allowed.



J. Any deviation in the duct system must be submitted as a shop drawing and stamped. CAUTION: Any deviation not submitted and favorably reviewed will be ordered removed from the system and replaced with that which is shown on the Drawings.

K. Discrepancies between actual field conditions and the Contract Documents shall be

brought to the attention of the Architect prior to fabrication. L. Field Changes to Ductwork: Field changes of ducts such as those required to suit

the sizes of factory-fabricated equipment actually furnished shall be designed to minimize expansion and contraction. Use 4:1 transitions in field changes as well as modifications to connecting ducts.

M. Transitions with a slope greater than 4 to 1 shall be ordered removed from the

system and replaced with a transition which meets this criteria. N. Joints and seams at intake and exhaust plenums and joints on intake and exhaust

ductwork for a distance of 3 feet from the plenum shall be sealed watertight on the bottom and side joints and seams.

O. Isolation dampers at intake and exhaust louvers and vent hoods shall be sealed to

the ductwork to provide an airtight assembly with similar performance characteristics to the isolation damper.

P. The inside of sheetmetal connections to grilles, registers and diffusers shall be

painted flat black so that no sheetmetal is visible from the finished space. Q. All sharp edges and corners on ductwork, hangers or equipment located within 7'-0"

of the finished floor shall be protected with a suitable padding material and identified with fluorescent orange paint.

3.3 CLOSING IN WORK A. Cover up or enclose work after it has been properly and completely tested and

reviewed. B. No additional cost to the Owner will be allowed for uncovering or recovering any

work that is covered or enclosed prior to required test and review. 3.4 TEST AND ADJUST A. Ductwork shall be leak tested in accordance with Section 23 05 93 "Testing and

Balancing for HVAC". Provide end cap and closure pieces. Close off and seal openings in ductwork to be tested. Ductwork shall be tested before it is insulated.

B. Before operating any system, the system shall be cleaned out to remove dust and

foreign materials. C. After the installation is complete and ready for operation, test the system under

normal operating conditions in the presence of the Architect and demonstrate that the system functions as designed.



D. Correct defects which develop during the test period, conduct additional testing until

defect free operation is achieved.



3.5 CLEANUP AND CORROSION PREVENTION A. Ductwork and equipment shall be thoroughly cleaned. Dirt, dust, and debris shall be

removed and the premises left in a clean and neat condition. B. Before covering is applied to duct systems, clips, rods, clevises and other hanger

attachments, and before uncovered piping is permitted to be concealed, corrosion and rust shall be wire brushed and cleaned and in the case of iron products, a coat of approved protective paint applied to these surfaces.

3.6 INSTRUCTIONS A. On completion of the project, instruct the Owner's representative in the care and

operation of the system. The total period of instruction shall not exceed four (4) hours. The time of instruction shall be arranged with the Owner. In addition to the prime Mechanical Contractor, the control system Contractor, Balancing Contractor, and Owner's representative shall be present and participate in the Owner's instruction.

3.7 FIRESTOPPING

A. Firestopping shall be performed in accordance with Specification Section 078413 “Firestopping”. All penetrations of fire-rated assemblies including walls and floors by mechanical system components (piping, ductwork, conduits, etc.) shall be firestopped as specified.
