The Ø 200 50mm Offset Internal Clay Adaptor - Ø 150 from National Flues is specifically designed for connecting to the bottom of chimney stacks that have a clay liner installed without a chimney flue liner. Constructed from 1mm thick stainless steel grade 316, it guarantees durability and longevity. Before installation, ensure that the existing clay liner has been smoke tested to verify its good condition.

The tapered end of the adaptor allows for a snug fit inside the unevenly shaped clay liner. Securing bands and stainless screws are used to fix the adaptor securely, while Fire Cement and Fire Rope are necessary to achieve an airtight seal. Finish off the installation by placing the single wall pipe over the spigot of the adaptor and sealing it with Fire Cement or Fire Rope.

Prior to installation, ensure that your existing clay liner has been thoroughly smoke tested to confirm its integrity. Insert the tapered end of the adaptor into the unevenly shaped clay liner to achieve a secure, snug fit. Secure the adaptor using appropriate stainless screws and securing bands. To complete the installation, position the single wall pipe over the adaptor's spigot and seal firmly using Fire Cement or Fire Rope, ensuring an airtight connection. Always follow manufacturer guidelines and safety instructions during installation.

This adaptor is used to connect the bottom of chimney stacks with an existing clay liner, especially when a chimney flue liner is not being installed.

The clay adaptor is made from 1mm thick stainless steel grade 316, ensuring durability and resistance to corrosion.

Ensure that the existing clay liner has been smoke tested to confirm it's in good condition before installing the adaptor.

The tapered end of the adaptor is designed to fit snugly inside the unevenly shaped clay liner. Use securing bands and stainless screws to fix it in place, then seal it with Fire Cement and Fire Rope.

This internal clay adaptor is available in offsets of 25mm, 50mm, and 75mm.

You will need securing bands, stainless screws, Fire Cement, and Fire Rope for a secure and airtight installation.

No, the internal fit adaptor should only be used when the clay liner does not protrude by at least 50mm from the stack.
