Chimney Roof Penetration Jeremias TWIN52080/125 stainless steel 80/125 for flat roof

Jeremias chimney roof penetration TWIN52080/125 stainless steel 80/125 for flat roof is an adapter component designed to route an 80/125 mm concentric or twin-wall flue through a flat roof while maintaining a sealed, corrosion-resistant transition. Manufactured to be compatible with Jeremias TWIN systems, the unit provides a compact passage for combustion gases and air intake in combined flue configurations used in residential and light-commercial heating installations.

Advantages

The stainless steel construction offers corrosion resistance and dimensional stability under typical flue temperatures, reducing the need for frequent replacement. The design ensures a sealed roof penetration that helps to prevent water ingress and preserve roof insulation integrity. Compatibility with Jeremias TWIN concentric/twin-wall systems simplifies installation planning and supports a consistent flue geometry through the roof plane.

Suitable for

• Routing 80/125 mm concentric or twin-wall flues through flat roofs
• Residential boilers, water heaters and small commercial heating appliances
• Retrofit projects where a reliable sealed roof passage is required

Key specifications

• Material: stainless steel
• Flue diameter: 80/125 mm (concentric/twin-wall configuration)
• Application: flat roof penetration
• Compatibility: Jeremias TWIN concentric/twin-wall flue systems
• Function: sealed transition for exhaust and air intake in combined flue systems

How to use

Position the chimney roof penetration at the planned roof opening and ensure the surrounding roof structure and insulation are prepared to receive a sealed penetration. Insert the corresponding 80/125 mm concentric or twin-wall flue elements into the adapter and secure per Jeremias system instructions and local building codes. Verify the seal against water ingress and confirm that inner and outer conductors are correctly aligned and mechanically supported to prevent strain on the roof penetration.

Usage recommendations

Installations should follow Jeremias installation guidelines and local regulations. Use appropriate flashing, sealing materials and mechanical supports compatible with stainless steel components. Periodic visual inspections are recommended to check seals and structural fixings, especially after severe weather or maintenance work on the roof or flue system.
