## Long description

Jeremias Adapter flue connector 60/100→80/125 for Immergas boilers TWIN1820701080125 is a metal coupling piece designed to join concentric or coaxial flue sections with an inner/outer diameter of 60/100 mm to sections with inner/outer diameter of 80/125 mm. It provides a reliable transition between different flue sizes to ensure proper exhaust routing from compatible Immergas boiler models. The adapter is intended for use where a change in flue diameter is required during installation, replacement or retrofit work and supports safe evacuation of combustion gases when installed according to manufacturer instructions and applicable regulations.
Advantages
The adapter offers a precise diameter transition with a rigid metal construction that maintains alignment between concentric flue segments. Its design minimizes leakage risks at the joint and preserves the integrity of the coaxial flue path, reducing the potential for backflow or condensation issues. The component is compact and engineered to fit commonly used concentric systems, facilitating straightforward integration into existing flue runs without complex modifications.
Suitable for
Transitioning concentric/coaxial flue pipes from 60/100 mm to 80/125 mm
Retrofit or replacement where boiler flue diameter differs from existing ducting
Installation on compatible Immergas boilers requiring a diameter adapter
Applications needing a secure metal coupling to maintain coaxial exhaust routing
Key specifications
Type: Concentric/coaxial flue adapter (diameter transition)
Input diameter: 60/100 mm (concentric inner/outer)
Output diameter: 80/125 mm (concentric inner/outer)
Material: Metal construction suitable for flue exhaust use
Compatible connection: Designed for use with Immergas boiler flue systems that require this diameter transition
How to use
Install the adapter between the existing 60/100 mm concentric flue section and the 80/125 mm section, ensuring both ends are fully engaged and aligned. Follow the boiler manufacturer’s instructions and flue system guidelines for sealing, support, and orientation of concentric ducts. Verify that the adapter is correctly seated and secured to prevent movement; check for proper slope and condensate drainage if applicable. After installation, perform a combustion gas tightness check and system test according to local codes and the boiler’s commissioning procedure.
Usage recommendations
Use this metal adapter only with compatible concentric flue components and Immergas boilers that require a 60/100 to 80/125 transition. Do not modify the adapter or use it with non-compatible materials. Installation and pressure/leakage testing should be carried out by a qualified technician in accordance with local regulations and the boiler manufacturer’s instructions.
