Chimney liner WADEX 100 mm, stainless-steel flexible flue liner, length 1 m

WADEX chimney liner with a 100 mm internal diameter and 1 m length is a stainless-steel flexible flue liner engineered for relining, extending or repairing chimneys and stovepipes. The product provides a continuous, corrosion-resistant pathway for combustion gases from fireplaces, wood stoves and boilers, enabling safe and efficient venting where a 100 mm flue connection is required. Its flexible construction allows installation through existing chimneys and bends without major masonry work.

Advantages

The stainless-steel construction offers resistance to corrosion and high temperatures, while flexibility simplifies routing through existing chimney channels. The 100 mm internal diameter maintains appropriate draft for small to medium solid-fuel appliances and ensures consistent exhaust flow. Its 1 m length makes it modular for custom installations and straightforward to join with compatible fittings and clamps.

Suitable for

• Relining deteriorated chimneys for wood stoves and fireplaces
• Extending stovepipes or chimney runs to reach appliances
• Repairing vent paths after masonry work or damage
• Use with small to medium solid-fuel boilers and multi-fuel stoves

Key specifications

• Internal diameter: 100 mm
• Length: 1 m
• Material: stainless steel flexible liner
• Suitable for venting combustion gases from solid-fuel appliances
• Corrosion-resistant and heat-tolerant construction

How to use

Measure the chimney or stovepipe run and determine the number of 1 m sections required. Feed the flexible liner down through the chimney or push it into the stovepipe, guiding it around bends as needed. Secure connections between sections with appropriate stainless-steel clamps or approved joining collars, and attach the upper and lower terminations to the appliance flue outlet and chimney cap or rain collar according to manufacturer guidance. Ensure the liner projects to the correct heights at the appliance and chimney terminations to maintain draft and prevent ingress of moisture.

Usage recommendations

Before installation, inspect the chimney for structural issues and creosote buildup; clean and repair as needed. Verify appliance compatibility with a 100 mm liner and follow local building codes and standards for flue installation. For permanent installations or where access is restricted, consider professional installation and a post-installation smoke or draft test to confirm safe operation.
