G. Sizes shown on plans are inside clear dimensions. Ductwork utilizing duct liner shall be in-creased in size to accommodate the duct liner thickness.


3.2 DUCT INSTALLATION

A. Drawings indicate general arrangement of ducts, fittings, and accessories. Minor modifications to route, size and shape of duct may be required to meet structural and other interference. Changes which could affect system performance shall be reviewed by Architect/Engineer prior to fabrication or installation of duct.

B. Construct and install each duct system for the specific duct pressure classification indicated.

C. Install ducts with fewest possible joints.

D. Install fabricated fittings for changes in directions, changes in size and shape, and connections.

E. Install couplings tight to duct wall surface with a minimum of projections into duct.

F. Install ducts, unless otherwise indicated, vertically and horizontally, parallel and perpendicular to building lines; avoid diagonal runs.

G. Install ducts close to walls, overhead construction, columns, and other structural and perma-nent enclosure elements of building.

H. Install ducts with a clearance of 1 inch, plus allowance for insulation thickness.

I. Conceal ducts from view in finished spaces. Do not encase horizontal runs in solid partitions, unless specifically indicated.

J. Coordinate layout with suspended ceiling, fire- and smoke-control dampers, lighting layouts, and similar finished work.

K. Electrical Equipment Spaces: Route ductwork to avoid passing through transformer vaults and electrical equipment spaces and enclosures.

L. Non-Fire-Rated Partition Penetrations: Where ducts pass through interior partitions and exteri-or walls, and are exposed to view, conceal space between construction opening and duct or duct insulation with sheet metal flanges of same metal thickness as duct. Overlap opening on four sides by at least 1-1/2 inches.

M. Fire-Rated Partition Penetrations: Where ducts pass through interior partitions and exterior walls, install appropriately rated fire damper, sleeve, and fire-stopping sealant. Contractor shall be responsible to coordinate appropriately rated fire damper with supplier and engineer. All fire dampers shall be dynamically rated unless otherwise approved by Engineer and Authority Hav-ing Jurisdiction.

3.3 HANGER AND SUPPORT INSTALLATION

A. Comply with SMACNA's "HVAC Duct Construction Standards - Metal and Flexible," Chapter 5, "Hangers and Supports."

B. Building Attachments: Concrete inserts, powder-actuated fasteners, or structural-steel fasteners appropriate for construction materials to which hangers are being attached. 1. Where practical, install concrete inserts before placing concrete. 2. Install powder-actuated concrete fasteners after concrete is placed and completely cured. 3. Use powder-actuated concrete fasteners for standard-weight aggregate concretes or for

slabs more than 4 inches thick. 4. Do not use powder-actuated concrete fasteners for lightweight-aggregate concretes or for

slabs less than 4 inches thick. 5. Do not use powder-actuated concrete fasteners for seismic restraints.

C. Hanger Spacing: Comply with SMACNA's "HVAC Duct Construction Standards - Metal and Flexible," Table 5-1, "Rectangular Duct Hangers Minimum Size," and Table 5-2, "Minimum Hanger Sizes for Round Duct," for maximum hanger spacing; install hangers and supports with-in 24 inches of each elbow and within 48 inches of each branch intersection.

D. Hangers Exposed to View: Threaded rod and angle or channel supports.

E. Install upper attachments to structures. Select and size upper attachments with pull-out, ten-sion, and shear capacities appropriate for supported loads and building materials where used.

3.4 PROTECTION OF DUCTWORK ON SITE


A. Ductwork stored on site as well as installed ductwork that is left open to construction activities shall be covered. Provide protective coverings on open ends of ductwork to prevent excessive accumulation of dust and debris on interior surfaces. Protection and storage of ductwork shall be in accordance to SMACNA's 'Duct Cleanliness for New Construction'.

3.5 SEAM AND JOINT SEALING

A. Low Pressure Ductwork: Seal per SMACNA Seal Class “C”. Sealant material shall be installed per manufacturer’s recommendations.

B. Seal externally insulated ducts before insulation installation.

3.6 HANGING AND SUPPORTING

A. Install rigid round, rectangular, and flat-oval metal duct with support systems indicated in SMACNA's "HVAC Duct Construction Standards--Metal and Flexible."

B. Support horizontal ducts within 24 inches of each elbow and within 48 inches of each branch in-tersection.

C. Support vertical ducts at a maximum interval of 16 feet and at each floor.

3.7 DUCT ACCESSORY INSTALLATION

A. Install duct accessories according to applicable details shown in SMACNA's "HVAC Duct Con-struction Standards--Metal and Flexible" for metal ducts.

B. Install volume dampers at locations indicated and at all branch take-offs to air outlets and inlets.

C. Provide fire and smoke dampers at locations indicated and where required by applicable codes. Install fire and smoke dampers according to manufacturer's UL-approved written instructions.

D. Provide turning vanes in all mitered elbows and duct turns.

E. Install duct access panels for access to inlet side of coils, equipment, control dampers, fire dampers, and smoke dampers.

F. Final connections to air outlets and terminal units may be made with flexible duct. Install flexi-ble ducts with metal collars or sleeves with draw bands. Length of flexible duct shall not ex-ceed 24”. Change of direction is not allowed with flexible ductwork.

G. Provide flexible connections to motor driven equipment. Secure fabric to duct or fan collar with 3/16” rivets space not more than 5” on center. Provide thrust restraints so that connections are not in tension with equipment in operation.

H. Install diffusers, registers, and grilles level and plumb, according to manufacturer's written in-structions, Coordination Drawings, original design, and referenced standards. Examine areas where diffusers, registers, and grilles are to be installed for compliance with requirements for installation tolerances and other conditions affecting performance of equipment. Do not pro-ceed with installation until unsatisfactory conditions have been corrected.

I. Install gas vents, chimneys, and stacks according to manufacturer's written instructions and NFPA 54. Locate to comply with minimum clearances from combustibles.

3.8 ADJUSTING

A. Adjust volume-control dampers in ducts, outlets, and inlets to achieve design airflow. Refer to Division 230593 Section "Testing, Adjusting, and Balancing" for detailed procedures.

B. Adjust duct accessories for proper settings and actions.

3.9 CLEANING

A. After completing system installation, inspect the system. Vacuum ducts before final acceptance to remove dust and debris.

B. After installation of diffusers, registers, and grilles, inspect exposed finish. Clean exposed sur-faces to remove burrs, dirt, and smudges. Replace diffusers, registers, and grilles that have damaged finishes.

C. Clean exposed ductwork surfaces to remove burrs, dirt, and smudges. Repair dented or dam-aged exposed ductwork and touch up paint defects or damage.
