Chimney liner WADEX CHIMNEY LINER 104 1 M OVAL — oval flue liner, 1 m length

WADEX CHIMNEY LINER 104 1 M OVAL is an oval flue liner section supplied as a one-metre length. Manufactured for insertion into existing chimney systems, this oval-profile liner guides combustion gases from compatible heating appliances and provides a protective channel inside masonry or prefabricated flues. It is intended for situations where an oval cross-section is needed to match appliance outlet geometry or to fit specific chimney shapes during repair and renovation work.

Advantages

The oval design enables better fit in chimneys with non-circular passages and helps maintain a consistent flue path for exhaust gases. A prefabricated 1 m length simplifies installation and replacement of damaged sections, while the standardized profile ensures compatibility with other liner sections and connectors. The liner reduces direct exposure of masonry to combustion by-products and aids in maintaining draught performance when installed correctly.

Suitable for

• Repairing or relining existing masonry chimneys that require an oval profile
• Connecting boilers, stoves or other heating appliances with oval outlets to a flue
• Renovation projects where a modular 1 m liner length is preferable for access and handling
• Situations where a tailored flue cross-section improves clearance and fit within constrained chimney shafts

Key specifications

• Profile shape: oval cross-section suitable for non-circular flue passages
• Length: 1 metre per section for modular installation
• Material: metal construction designed for directing combustion gases (material specifics depend on manufacturer standard)
• Application: intended for use with compatible heating appliances and existing chimney systems
• Installation: designed for insertion and joining with matching liner sections and connectors

How to use

Measure the internal dimensions of the existing chimney to confirm the oval profile and select the required number of 1 m sections to achieve the necessary flue length. Insert each WADEX oval liner section into the chimney from the top or bottom as appropriate, ensuring sections are aligned and joined securely using compatible connectors or sealing methods recommended for metal flue liners. Verify clearances to combustible materials and ensure a continuous, unobstructed path for exhaust gases before commissioning the heating appliance.

Usage recommendations

Have a qualified installer or chimney professional assess the chimney condition and perform the installation to ensure correct fit, sealing and compliance with local building and safety regulations. Regular inspection and maintenance of the liner and chimney are advised to maintain safe and efficient operation.
