4. Installation Guidelines
The STI Fire Barrier Restraining Collar is designed to be installed around penetrating items (e.g., pipes, conduits) in fire-rated walls or floors to maintain the fire resistance rating of the assembly. Proper installation is crucial for the product's effectiveness.

General Installation Steps:
- Preparation: Ensure the opening in the fire-rated assembly is clean and free of debris. Identify the specific penetrant (e.g., pipe) that requires firestopping.
- Sizing: Measure the circumference of the penetrant. The 25 ft. length of the collar allows for custom sizing to fit various diameters. Cut the collar to the appropriate length, ensuring sufficient overlap for secure fastening.
- Wrapping: Wrap the collar tightly around the penetrant, ensuring it is flush against the fire-rated assembly surface. The pre-punched holes are designed for easy attachment.
- Securing: Fasten the collar securely to the fire-rated assembly using appropriate fasteners (e.g., screws, anchors) through the pre-punched holes. Ensure a tight fit to prevent smoke and fire passage. Refer to local building codes and manufacturer's specific installation instructions for fastener type and spacing.
- Sealing: Apply an approved firestop sealant or caulk to all gaps and seams between the collar, the penetrant, and the fire-rated assembly to ensure a complete fire and smoke seal.
- Inspection: After installation, visually inspect the collar and sealant application to ensure it meets all firestopping requirements and is free from gaps or defects.
Note: Always consult the specific installation instructions provided by STI for the SSWRC2 model and any relevant building codes or standards applicable to your region. Professional installation is recommended for critical fire safety applications.
5. Maintenance
The STI Fire Barrier Restraining Collar is designed for long-term performance with minimal maintenance. However, periodic inspection is recommended to ensure its continued integrity and effectiveness.
- Visual Inspection: Annually, or as required by local regulations, visually inspect all installed collars for any signs of damage, corrosion, or displacement.
- Sealant Integrity: Check the firestop sealant around the collar for cracks, shrinkage, or degradation. Reapply or repair sealant as necessary using an approved firestop product.
- Structural Integrity: Ensure the collar remains securely fastened to the fire-rated assembly and that there are no loose connections.
- Damage: If any damage is observed (e.g., bending, punctures), the collar's firestopping capability may be compromised. Consult with a fire safety professional or the manufacturer for repair or replacement options.
6. Troubleshooting
As a passive fire protection component, the Fire Barrier Restraining Collar typically does not require "troubleshooting" in the traditional sense. Its function is to provide a fire barrier when exposed to fire conditions.
If you encounter issues related to the physical installation or integrity of the collar, consider the following:
- Loose Collar: If the collar becomes loose, re-secure it using appropriate fasteners. Ensure the fasteners are compatible with the fire-rated assembly material.
- Gaps or Openings: Any visible gaps between the collar, penetrant, or fire-rated assembly must be sealed with an approved firestop sealant to maintain the fire rating.
- Damage to Collar: If the collar itself is bent, punctured, or otherwise damaged, its firestopping performance may be compromised. It is recommended to replace the damaged section or the entire collar if necessary.
For any concerns regarding the firestopping performance or proper application of the product, it is highly recommended to consult with a qualified fire protection engineer or contact STI technical support.
