-
Pre-cut and pre-assemble as much of each run as possible at grade level. Prepare common runs together.
-
Lengths can be cut to size with a cut-off saw.
- Use #8 × 1/2" sheet metal screws to attach components.
- Use couplers to join two lengths. Screw top, bottom and tape. Joints are flexible and can be used for minimal offsets.
IMPORTANT: To ensure proper damper operation, install wall discharge as indicated by labels. - Move pre-assembled components to installation floor.
-
Install ECCODUCT™ before the top course of rebar or post tensioning cables are laid in place. WARNING: NO FOOT TRAFFIC ON DUCTWORK.
- Screw discharge fittings to forms using #8 × 3/4" sheet metal screws. Check to ensure that wall discharge is installed correctly as indicat
ed by labels.
- Slide remaining lengths into place as previously marked out. TAPE ALL JOINTS WITH TAPE APPROVED BY THE ENGINEER.
- Attach plastic support brackets with #8 × 1/2" sheet metal screws to both sides every 5' maximum and at all joints and couplers. Screw brackets down with #8 × 3/4" screws.
- Pour slab. Inspect for damage. Replace or repair as needed
- Remove forms after curing.
- Tabs on inlet boot are bent down later when attaching pipe from fan.
