Flue Pipe Element for Wall Exhaust Almeva LIK 0.55 m DN80/125

Almeva LIK flue pipe element for wall exhaust is a stainless concentric duct section designed to route combustion gases through external walls. With a length of 0.55 m and nominal diameters DN80/125, this rigid element forms part of balanced-ventilation concentric flue systems for gas appliances. It provides a straight, corrosion-resistant connection section for reliable evacuation of exhaust gases and straightforward integration into wall penetrations for residential and light-commercial installations.

Advantages

The Almeva LIK element offers a compact 0.55 m length that simplifies on-site installation where short wall penetration sections are required. Constructed from stainless materials, it resists corrosion from condensate and flue gases, ensuring long-term dimensional stability. Its concentric DN80/125 geometry supports combined supply and exhaust routing in a single assembly, reducing the number of separate parts and maintaining correct flow paths for balanced-ventilation systems.

Suitable for

• Routing exhaust and air supply for gas-fired boilers and condensing boilers through external walls
• Concentric flue systems in apartments, single-family houses and small commercial premises
• Short wall penetration runs where a rigid stainless connection piece is required

Key specifications

• Length: 0.55 m
• Nominal diameters: DN80/125 (concentric)
• Material: stainless construction for the flue section
• Compatibility: designed for concentric balanced-ventilation flue systems
• Application: wall exhaust connection element for gas appliances

How to use

Install the flue pipe element as part of the concentric flue assembly, positioning it through the wall opening so the outer and inner ducts align with the adjacent components. Follow the appliance and system manufacturer instructions for sealing, fixing and connection order; ensure proper alignment and secure mechanical fixing to prevent movement. Check that the outer casing is continuous with the building wall penetration sleeve and that the inner exhaust path is unobstructed before commissioning the appliance. Final installation should include a leak and draft inspection in accordance with local codes.

Usage recommendations

Verify compatibility with the specific concentric flue system and appliance model prior to installation. Use appropriate insulation or wall sleeves where required by building regulations, and perform routine visual inspections for corrosion, condensate accumulation or mechanical damage during maintenance intervals.
