SpiroFlex two‑wall flue pipe TURBO 60/100, 0.5 m

SpiroFlex two‑wall flue pipe TURBO 60/100, 0.5 m is a concentric two‑wall (DWZ) flue section designed for turbo (balanced) gas appliance systems. The product features an inner and outer duct arranged concentrically to provide a direct exhaust path for combustion gases while admitting combustion air through the outer annulus. With a concentric diameter of 60/100 mm and a length of 0.5 m, this flue section is intended for use where compact, space‑efficient routing and balanced venting are required for turbo boilers, water heaters and other balanced‑venting gas appliances.

Advantages

The concentric two‑wall construction ensures separated channels for exhaust and incoming combustion air, reducing installation complexity in confined spaces compared with separate coaxial assemblies. The short 0.5 m length allows precise alignment and incremental routing when connecting turbo appliance outlets to longer duct runs or termination fittings. The product is built to integrate with balanced flue systems, offering consistent internal dimensions and stable flow characteristics suitable for turbo appliances that require concentric intake/exhaust configuration.

Suitable for

• Connecting turbo (balanced) gas boilers to concentric flue systems
• Routing exhaust and combustion air for turbo water heaters
• Compact concentric installations where space is limited
• Modular assembly of balanced‑venting ductwork in residential and light‑commercial applications

Key specifications

• Concentric diameters: 60 mm (inner) / 100 mm (outer)
• Length: 0.5 m
• Two‑wall concentric (DWZ) configuration providing separate inner and outer channels
• Designed for turbo/balanced gas appliance flue systems
• Straight pipe section for inline routing and connection to compatible fittings

How to use

Measure the required run and position the 0.5 m SpiroFlex concentric section to align with the appliance outlet and adjoining ductwork. Insert the inner and outer concentric ends into compatible fittings or adjacent concentric sections according to the appliance manufacturer’s installation instructions. Ensure proper sealing and support at joints to maintain concentric alignment and to prevent movement. Observe clearances and local regulations for balanced flue systems during installation and commissioning.

Usage recommendations

Use this concentric section as part of a complete balanced‑venting system. Verify compatibility with the specific turbo appliance model and follow appliance and local building codes for materials, clearances, and termination. Regular inspection for secure joints and unobstructed air paths is advised after installation.
