Chimney inner sleeve WADEX model 024110150 for flue diameters 110/150 mm

WADEX chimney inner sleeve model 024110150 is an internal flue component designed for chimneys with flue diameters of 110 mm and 150 mm. The sleeve creates a smooth, heat-resistant lining within an existing chimney shaft to support efficient draught, protect masonry from soot and condensate, and guide combustion gases safely out of the building. It is intended for retrofit and new installations in residential and light-commercial heating systems where a dual-diameter solution is required.

Advantages

The chimney inner sleeve provides a continuous, corrosion-resistant pathway for flue gases and reduces hotspots in the chimney masonry. Its dimensions accommodate two commonly used flue diameters, enabling compatibility with a range of appliances and transition pieces. Installation of the sleeve helps maintain consistent draught performance and reduces the need for frequent masonry cleaning by limiting soot deposits and condensate penetration.

Suitable for

• Residential boilers, furnaces or stoves with 110 mm or 150 mm flue connections
• Retrofit of older chimneys to improve draught and flue safety
• New chimney installations in single-family homes and light-commercial properties
• Situations requiring a lining that resists combustion byproducts and moisture

When it may not be suitable

The sleeve is not intended to change the overall chimney structural layout or to serve as a primary structural element; it functions as an internal lining only. It may not be suitable where the chimney requires full relining with a different material, where flue diameters differ from 110/150 mm, or where specific appliance manufacturers require a bespoke liner design.

Key specifications

• Compatible flue diameters: 110 mm and 150 mm
• Function: internal chimney lining for guiding combustion gases and protecting masonry
• Intended use: residential and light-commercial heating systems, retrofit and new installations
• Material characteristics: heat-resistant and corrosion-resistant lining suitable for typical combustion byproducts

How to use

Measure the chimney shaft and verify compatibility with the specified 110 mm / 150 mm flue diameters before installation. The sleeve should be inserted and positioned according to local building codes and manufacturer instructions, ensuring secure joints and correct alignment with the appliance flue outlet. After installation, seal any wall or roof penetrations, check draught performance, and commission the heating appliance following standard safety checks. Use a qualified installer when required by regulations.

What to consider before purchase

• Confirm the appliance flue outlet diameter (110 mm or 150 mm) and chimney internal dimensions
• Check local building regulations and any appliance manufacturer requirements for lining materials
• Assess whether a professional installer is needed for compliance and safety
• Ensure compatibility with existing chimney masonry, supports, and access points for installation

Usage recommendations

Regularly inspect the lined chimney for soot buildup and condensate. Schedule professional sweeps and maintenance according to fuel type and appliance usage to preserve draught performance and safe evacuation of gases.
