Chimney liner WADEX 1031000006 — oval shape flue liner

WADEX 1031000006 oval shape flue liner is a purpose-built chimney liner designed to restore and upgrade flue channels with a non-circular cross-section. The oval profile allows a closer fit to existing chimney cavities, improving draft stability and promoting the safe evacuation of combustion gases from residential and light commercial heating appliances. Constructed for installation within masonry or prefabricated chimneys, this liner is intended for use where a tailored flue geometry is required.

Advantages

The oval-shape design provides improved contact with chimney walls compared with circular liners in rectangular or oval channels, reducing gaps and helping to stabilise flue draft. The liner is engineered for resistance to typical chimney conditions, ensuring a secure passage for exhaust gases while facilitating retrofitting without major modifications to the chimney structure. Its geometry assists in achieving effective gas flow and can reduce turbulence that sometimes occurs in mismatched liner shapes.

Suitable for

• Lining or relining masonry chimneys with an oval or rectangular flue channel
• Refurbishment projects in residential buildings
• Light commercial premises requiring a tailored flue profile
• Installation where improved fit and draft stability are required

Key specifications

• Shape: oval profile designed for non-circular flue channels
• Function: provides a dedicated passage for combustion gas exhaust
• Application environment: indoor chimney and flue refurbishment or installation
• Compatibility: intended for use with standard residential and light commercial heating appliances that exhaust into chimneys

How to use

Assess the existing chimney flue dimensions and condition to confirm the oval liner is an appropriate fit. Prepare the chimney by cleaning soot and debris and repairing any loose masonry as necessary. Insert the liner from the top or bottom following the installer’s access plan, ensuring the profile aligns with the flue channel and that joints between liner sections are sealed according to accepted chimney installation practices. Secure and connect the liner to the appliance outlet or chimney termination as required and perform a smoke or draft test to verify correct operation.

Usage recommendations

Follow local building codes and manufacturer installation guidelines. Use qualified personnel for sizing, cutting, joining, and sealing to ensure safe exhaust performance. Periodic inspection and cleaning of the flue liner are recommended to maintain safe operation and efficient draft.
