Flue and air duct on facade KRUPS DN60/100 L=1000mm

Flue and air duct on facade KRUPS DN60/100 L=1000mm is a facade-mounted concentric duct designed to route combustion air to the appliance and expel flue gases through an external wall. The unit combines an inner flue and outer air intake in a single sleeve with DN60/100 diameters and a 1000 mm length, allowing installation where a direct rear or roof outlet is not possible. The product is intended for use with compatible heating appliances and provides a controlled passage for exhaust and fresh air while supporting condensate drainage and weather protection at the building envelope.

Advantages

The concentric design integrates intake and exhaust in one compact assembly, reducing the number of separate components and simplifying alignment during installation. Its 1000 mm length offers flexibility for varying facade thicknesses and mounting depths. Constructed for outdoor mounting, the duct supports safe separation of combustion products from living spaces and helps maintain appliance performance by ensuring a dedicated air supply. The design facilitates condensate runoff and creates a straightforward secure connection to appliance terminals.

Suitable for

• Concentric flue installations through external walls for residential boilers and water heaters
• Buildings where rear or roof vents are impractical or restricted
• Renovation projects requiring an externally mounted combined intake and exhaust duct

Key specifications

• Concentric duct with inner and outer diameters DN60/100
• Overall length: 1000 mm
• Facade-mounted configuration for external wall passage
• Designed for combined air intake and flue gas exhaust
• Provides provision for condensate drainage and secure terminal connection

How to use

Position the duct to align with the appliance terminal and the external wall opening, ensuring the 1000 mm sleeve covers the building insulation and wall thickness as required. Follow the appliance manufacturer's instructions for concentric connections: secure the inner and outer tubes, seal the joint to prevent water ingress around the wall penetration, and verify the correct orientation of intake and exhaust. After mechanical fastening, check that condensate drainage is unobstructed and that the external terminal is mounted according to local building codes. Perform a functional test of the heating appliance to confirm correct air supply and exhaust flow.

Usage recommendations

Use this duct only with appliances and terminal kits specified by the appliance manufacturer. Ensure installation by a qualified technician in accordance with local regulations and industry standards. Inspect the external terminal periodically for debris or blockage and verify seals after severe weather. Replace or repair any damaged sections to maintain safe exhaust performance.
