Flue Elbow 90/120 WADEX – 90° flue elbow for 120 mm coaxial flue systems

WADEX Flue Elbow 90/120 is a 90-degree elbow designed for 120 mm coaxial flue systems. It redirects exhaust and intake airflow to allow compact routing of coaxial flue pipes in tight installations, for example when running a flue behind a boiler or through a wall. The component is intended for gas appliance venting where a change of direction is required and is compatible with other 120 mm coaxial components.

Advantages

This flue elbow provides a secure 90° change of direction while maintaining the concentric airflow of a coaxial system. The product is manufactured for durability and safe exhaust flow, reducing backpressure and preserving the designed path for combustion gases and fresh air intake. Its standardized 120 mm diameter ensures compatibility with matching coaxial sections, simplifying installation and replacement.

Suitable for

• Routing coaxial flue pipes behind boilers or heaters
• Changing direction of exhaust and intake in confined spaces
• Wall penetrations where a compact elbow is required
• Gas appliance venting systems with 120 mm coaxial components

Key specifications

• Angle: 90 degrees for a single right-angle turn
• System type: coaxial (concentric) flue application
• Nominal diameter: 120 mm internal concentric diameter
• Material: rigid construction suitable for exhaust and intake airflow handling
• Compatibility: designed to join with other 120 mm coaxial flue components

How to use

Install the elbow as part of the coaxial flue run, ensuring that the concentric inner and outer ducts remain aligned and that connections are secured according to the flue system manufacturer's instructions. Position the elbow to achieve the required 90° deviation, allowing sufficient access for sealing and mechanical fastening. Check clearances to combustible materials and follow local building and gas safety regulations during routing and assembly.

Usage recommendations

Verify compatibility with the specific boiler or gas appliance and the rest of the coaxial system. Use appropriate sealing and fixation methods, and have installation and commissioning performed or checked by a qualified technician to ensure safe operation and compliance with regulations.
