Concentric Flue Base 80/125 Immergas K.011957

The Concentric Flue Base 80/125 Immergas K.011957 is a mounting and connection component designed for 80/125 mm coaxial flue systems used with central heating boilers. It provides a compact and secure interface for concentric exhaust and air intake pipes, ensuring correct alignment and a sealed connection between the boiler and the flue system. The component is intended for installations where a space-saving coaxial ducting solution is required for ventilation and combustion gas routing.

Advantages

The flue base supports concentric 80/125 mm flue configurations and is manufactured to match the dimensional requirements of compatible boiler outlets and coaxial ducts. It simplifies installation by providing a single component that aligns intake and exhaust pipes concentrically, helping to reduce installation time and minimize the risk of leaks at the connection point. The design contributes to reliable sealing and consistent airflow for safe combustion and exhaust discharge.

Suitable for

• Residential and small commercial gas-fired central heating boilers with 80/125 mm coaxial flue systems
• Ventilation and exhaust routing where concentric intake/exhaust connection is required
• Retrofit or replacement of existing concentric flue base components of compatible dimensions

Key specifications

• Compatible concentric pipe diameter: 80/125 mm
• Function: mounting and sealed connection for concentric intake/exhaust ducts
• Design: compact coaxial interface for combined air intake and combustion gas exhaust
• Application environment: indoor or sheltered flue terminations as specified by boiler and installation standards

How to use

Position the concentric flue base so that its spigot aligns with the boiler outlet and the coaxial duct sections. Ensure mating surfaces are clean and free of debris, then insert the inner and outer pipes concentrically through the base until they engage securely. Follow the boiler manufacturer's instructions and local installation codes for fastening, sealing, and clearances. Verify that the connection is tight and that the concentric ducts are correctly supported to avoid stress on the joint.

Usage recommendations

Use the flue base only with compatible 80/125 mm coaxial flue components and boilers; always observe the boiler manufacturer's installation instructions and applicable national or local regulations. Perform a leak and combustion gas flow check after installation and schedule regular inspections as part of routine boiler maintenance.
