Flue Pipe with Collar Almeva LIK 0.25 m DN60/100 LPRK05

The Almeva LIK flue pipe with collar, length 0.25 m and nominal diameter DN60/100, is a short coaxial adapter section intended for use in coaxial or concentric chimney systems. It is designed to create a sealed connection between the appliance outlet and the chimney system, providing a compact extension or replacement section where a collar is required. The component is suitable for residential and light-commercial heating installations that use DN60/100 concentric flue components.

Advantages

The flue pipe is manufactured for compatibility with DN60/100 concentric chimney components and includes an integrated collar to secure and seal the junction. Its short 0.25 m length allows precise adjustment of connection length without excess material, reducing the need for cutting or modifying other parts. The component is engineered for tight sealing and stable alignment of inner and outer ducts, supporting reliable evacuation of combustion gases when installed according to system requirements.

Suitable for

• Connecting a DN60/100 coaxial appliance to a concentric chimney system
• Extending or adjusting the length of a coaxial flue run in residential boilers or water heaters
• Repairing or replacing a short section of a concentric flue where a collar connection is needed
• Installations requiring compact, collar-equipped DN60/100 components

Key specifications

• Nominal diameter: DN60/100 (concentric/coaxial)
• Length: 0.25 m
• Feature: integrated collar for sealed junctions
• Application: coaxial/concentric chimney systems for gas appliances
• Installation environment: residential and light-commercial heating systems

How to use

Measure the required position in the flue run and insert the Almeva LIK 0.25 m section so that the collar aligns with the mating component. Ensure inner and outer ducts are correctly engaged and seated to obtain the designed concentric alignment. Follow the chimney system manufacturer’s instructions and applicable building codes for sealing, fastening, and support. Verify with a smoke or spillage test (or follow appliance commissioning procedures) that the connection is gas-tight and that combustion products are safely routed through the system.

Usage recommendations

Use only with compatible DN60/100 concentric components and gas appliances specified for coaxial flue systems. Do not modify the component beyond manufacturer-approved methods. Periodically inspect connections for integrity and signs of wear or corrosion, and have the entire flue system checked during regular appliance maintenance by a qualified technician.
