Almeva chimney elbow 87° DN80/125 LIK model LPBK98

Almeva chimney elbow 87° DN80/125 LIK model LPBK98 is a stainless-steel concentric elbow designed for DN80/125 coaxial flue systems. It provides an approximately 87° change in direction for flue gas and air intake paths in balanced-ventilation chimney installations. The component is intended for use with compatible gas boilers and other appliances that accept concentric DN80/125 pipe connections, enabling compact routing and alignment of exhaust ducts where a near-right-angle turn is required.

Advantages

The elbow is manufactured from corrosion-resistant stainless steel for long service life in condensing and non-condensing flue environments. Its concentric DN80/125 configuration keeps the exhaust and combustion air paths integrated, simplifying installation and maintaining system clearance requirements. The 87° angle offers close to a right-angle redirection while allowing slight tolerance for fittings and alignment in tight spaces. The part is compatible with standard DN80/125 LIK components, which reduces the need for additional adapters when integrating into existing systems.

Suitable for

• Concentric DN80/125 coaxial flue systems for residential heating
• Gas boilers and wall-hung appliances with DN80/125 connections
• Applications requiring a near-90° change of direction in exhaust routing
• Retrofit and new installations where compact duct routing is needed

Key specifications

• Material: stainless steel (corrosion-resistant)
• Angle: approximately 87° elbow for directional change
• Configuration: concentric/coaxial for combined exhaust and intake
• Nominal diameters: outer/inner concentric dimensions for DN80/125 systems
• Compatibility: designed for DN80/125 LIK concentric flue components

How to use

Install the elbow as part of a concentric DN80/125 flue run, ensuring the correct orientation so the exhaust and intake align with the appliance and external terminal. Slide or lock the mating DN80/125 sections together according to the system’s connection method and verify seals and support to prevent sagging or misalignment. Observe local regulations and manufacturer instructions for minimum clearances, condensate management, and support spacing. Use appropriate sealing rings or gaskets if required by the flue system design.

Usage recommendations

Before installation, confirm compatibility with the appliance manufacturer’s flue requirements and follow national installation codes. Periodically inspect the elbow and adjacent sections for signs of corrosion, blockages, or joint looseness, and ensure condensate drainage remains unobstructed in condensing-system applications.
