Jeremias chimney transition FLEX/EW ø80 (FD07080) for flue connection

Jeremias chimney transition FLEX/EW ø80 (FD07080) is an adapter designed to join flexible liner systems with rigid flue components in installations using ø80 mm ducts. It provides a secure mechanical connection between FLEX liners and elements of the EW system, intended for exhaust routing from gas and heating appliances. The transition piece enables a continuous flue path while maintaining alignment and a stable interface between different chimney system parts.

Advantages

The transition is manufactured to match the ø80 mm nominal diameter, ensuring consistent fit and compatibility with corresponding FLEX liners and EW components. Its construction supports a mechanical joint that reduces the risk of separation under normal operating conditions and facilitates installation in mixed flexible-rigid flue assemblies. The design helps maintain exhaust flow integrity and simplifies connecting flexible liners to standard rigid fittings.

Suitable for

• Connecting flexible chimney liners to rigid EW flue components with ø80 mm diameter
• Exhaust systems of gas boilers and heating appliances requiring a reliable liner-to-flue interface
• Renovation or repair work where an adapter is needed to join existing flexible and rigid chimney parts

Key specifications

• Nominal diameter: 80 mm
• Compatibility: Designed for use with FLEX liners and EW system elements of matching diameter
• Function: Mechanical transition piece for flue connection between flexible and rigid sections
• Application: Exhaust routing for gas and heating appliances
• Material: Suitable for typical chimney system materials used in FLEX and EW assemblies

How to use

Install the transition by inserting the flexible liner into the designated end and aligning the rigid EW component on the opposite side to form a secure mechanical joint. Ensure both mating parts are clean, free of debris, and fully seated to achieve stable engagement. Follow the appliance and chimney system manufacturer installation guidelines and local building codes regarding clearances, support, and fastening. Verify the assembled connection for proper alignment and mechanical stability before completing the chimney installation.

Usage recommendations

Use this transition only with compatible ø80 mm FLEX liners and EW system components. Periodically inspect the connection for signs of loosening, corrosion, or damage, and re-secure or replace parts as necessary. For installations involving gas appliances, have the completed chimney system verified by a qualified technician to confirm correct draft and safety compliance.
