Chimney Union Tee WADEX model 024180200 for circular flue Ø180/200 mm

Chimney Union Tee WADEX model 024180200 for circular flue Ø180/200 mm is a purpose-built tee connector for round chimney systems with nominal diameters of 180 and 200 mm. Designed to create a secure branch junction, this WADEX union tee enables connection of appliance outlets or secondary flue runs to the main chimney while maintaining alignment and exhaust flow characteristics required for safe venting in residential and light-commercial installations.

Advantages

The union tee provides a robust mechanical junction that accommodates two common circular flue sizes without the need for multiple adapters. Constructed to integrate with standard round ducting, it helps maintain consistent internal geometry for stable exhaust flow and reduces the risk of leaks when properly installed. The product supports straightforward assembly and service access to branch connections or inspection points.

Suitable for

• Residential chimney systems using circular flues with diameters 180 mm or 200 mm
• Light-commercial venting installations where a branch connection or appliance outlet must join the main flue
• Chimney installation, repair and maintenance tasks requiring a reliable tee junction

When it may not be suitable

This union tee is intended for circular flue systems sized for 180 mm and 200 mm diameters and may not be appropriate for rectangular, oval or significantly different diameter flues. It should not be used in systems that require specialist materials, pressure ratings, or certifications beyond those typical for standard residential and light-commercial chimney components.

Key specifications

• Compatible flue diameters: 180 mm and 200 mm
• Configuration: tee junction for circular flue systems
• Application: branch connection for appliance outlets or secondary runs
• Typical use environment: residential and light-commercial chimney venting

How to use

Install the union tee at the desired branch location in the chimney run, ensuring the main and branch pipes are clean and free of debris. Slide the flue sections into the tee until seated and secure connections according to chimney system guidelines, using appropriate sealing methods and fasteners where required. Verify alignment and slope for condensate and condensable products, and perform a leak check and visual inspection before finalizing the installation. Follow local building codes and appliance manufacturer instructions for clearances and connection methods.

What to consider before purchase

• Confirm the chimney flue diameter in your system is 180 mm or 200 mm
• Verify material compatibility and local code requirements for chimney components
• Ensure the tee configuration matches the intended branch orientation and appliance outlet

Usage recommendations

Use this WADEX union tee in combination with compatible circular flue components and follow manufacturer guidelines and local regulations. Periodic inspection and maintenance of junctions will help maintain safe venting performance.
