Installation Instructions: 

Step 1: Prepare the Roof Opening 

• Verify that the structural opening is clear and matches the hatch’s external dimensions. Ensure the opening size accounts for the flange, which should be structural opening + 11.75". 

Step 2: Positioning and Securing the Hatch 

• Place the hatch into the prepared opening and carefully align it. Use 5/16" screws or anchors to secure the hatch via the pre-punched 11/32" fixing holes in the flange. 

Step 3: Sealing 

• Apply fire-resistant mastic or sealant between the upstand flange and the roof membrane. This step is crucial for creating an airtight, fireproof, and weatherproof seal that maintains the hatch’s fire rating and overall performance. 

Step 4: Test the Gas Spring and Safety Stays 

• Check the gas spring-assisted opening mechanism for smooth operation, ensuring it opens up to 85°. Install wind restraints or safety stays for added security, especially in high-wind areas. 

Step 5: Locking Mechanism 

• Test the stainless-steel slam latch to ensure proper functionality. Verify that both internal and external locks are secured.

 
Helpful Maintenance and Safety Tips 

• Gas Spring Mechanism: Regularly inspect for wear and tear. If safety stays or wind restraints are installed, ensure they remain secure over time. 

• Hatch Insulation: Periodically check the integrity of the thermal break and insulation, particularly if the hatch includes optional mineral wool insulation. This will help maintain its U-value of 0.111 Btu/hr·ft²·°F. 

• Safety Precautions: Always use hold-open safety stays and wind restraints in areas prone to high winds to prevent accidental closures.
