Chimney Insert WADEX 180 mm Diameter, 0.5 m Length

WADEX chimney insert with a 180 mm internal diameter and 0.5 m length is a straight stainless steel connecting piece designed to provide a sealed passage for smoke and combustion gases. Intended as a short extension or replacement section, this insert fits flue systems where a 180 mm diameter is required and is suitable for connecting stoves, furnaces and residential chimney sections. Constructed to maintain the continuity of a flue while preventing leaks, the insert supports safe exhaust of combustion by-products when installed as part of a correctly configured chimney system.

Advantages

The stainless steel construction resists corrosion and withstands the high temperatures typical of stove and furnace exhausts while providing a smooth internal surface to promote efficient gas flow. Its standardized 180 mm internal diameter ensures compatibility with matching flue components, and the 0.5 m length offers a compact, easy-to-handle section for repairs or short extensions. The straight design simplifies alignment during installation and helps maintain a continuous, sealed flue path.

Suitable for

• Connecting wood stoves, pellet stoves or small furnaces to existing chimney flues
• Repairing damaged short sections of a residential chimney system
• Short extensions where a 180 mm diameter replacement section is needed
• Creating a sealed transition between two compatible flue components

How to use

Measure the existing flue and confirm matching 180 mm diameter before use. Slide the insert into or between compatible flue components so that the joints are properly engaged and aligned. Secure connections according to local building codes and manufacturer instructions for the whole chimney system, using appropriate clamps, screws or seals where required. Ensure the assembled flue maintains proper slope and clearances, and inspect all joints for tightness to prevent leakage of combustion gases.

Usage recommendations

Install and inspect this insert as part of a complete flue system; consult local regulations and a qualified installer when in doubt. Regularly check for signs of corrosion, soot buildup or joint degradation, and perform routine maintenance to ensure safe, efficient operation of connected heating appliances.
