## Summary description

Inner sleeve for chimney flue by WADEX, model 024100150, designed for concentric duct systems with inner/outer diameters of 100/150 mm. Serves as the inner lining that guides combustion gases, ensures correct concentric spacing and helps maintain safe exhaust flow. Suitable for installation in venting assemblies for boilers and heating appliances using concentric flues.

## Long description

The WADEX chimney flue inner sleeve 024100150 is an inner lining component intended for concentric duct systems with inner/outer diameters of 100/150 mm. It functions as the central passage for combustion gases, maintaining the concentric spacing between inner and outer ducts and helping to ensure stable exhaust flow for boilers and heating appliances connected to a concentric flue system.
Advantages
This inner sleeve is made to fit concentric flue assemblies where an inner duct of 100 mm and an outer duct of 150 mm are required, providing a precisely sized internal bore for exhaust gases. Its design supports consistent airflow and contributes to correct alignment inside the concentric system, reducing the risk of flow restrictions. The component simplifies installation and replaces worn or damaged inner liners without altering the outer conduit.
Suitable for
 Concentric flue systems with 100/150 mm inner/outer diameters
 Boilers and heating appliances using concentric vents
 Replacement of damaged or aged inner liners in vent assemblies
 Vent installations requiring maintained concentric spacing for safe exhaust
Key specifications
 Compatible concentric duct inner diameter: 100 mm
 Compatible concentric duct outer diameter: 150 mm
 Function: inner sleeve / inner lining for combustion gas passage
 Application: horizontal or vertical concentric vent runs for heating appliances
 Material characteristics: rigid lining suitable for exhaust gas guidance (manufacturer materials and finish as supplied)
How to use
Install the inner sleeve as part of the concentric flue assembly by inserting it into the corresponding outer duct that matches the 100/150 mm diameters. Ensure the sleeve is fully seated and aligned so the inner passage is concentric within the outer conduit. Follow appliance manufacturer instructions for connection to the boiler or heating device, and verify sealing and mechanical supports to prevent movement during operation. Perform a smoke or draft test where applicable to confirm correct exhaust flow after installation.
Usage recommendations
Use this inner sleeve only in compatible concentric duct systems with matching diameters and within the temperature and pressure limits specified by the heating appliance and flue system manufacturer. Inspect the sleeve periodically for signs of corrosion, deformation or blockage, and replace if damage is found. Always observe local codes and the appliance manufacturer’s service instructions when installing or servicing vent components.
