The Ø 200 25mm Offset Internal Clay Adaptor - Ø 150 is designed specifically for situations where a chimney stack has an existing clay liner and a chimney flue liner is not being installed. Crafted from 1mm thick stainless steel grade 316, this adaptor provides durability and longevity. The clay end of the adaptor is tapered to ensure a snug fit inside the clay liner, which is essential as clay liners are rarely perfectly symmetrical.
For a secure and airtight connection, use Fire Cement and Fire Rope around the clay liner. Additionally, stainless steel screws should be used to prevent corrosion, securing the adaptor effectively into place. The single wall pipe can then be placed over the adaptor's spigot and sealed with Fire Cement and/or Fire Rope for optimal safety and performance.

This material is renowned for its durability and corrosion resistance, making it perfectly suited for the challenging conditions often encountered in chimney installations.

This design helps achieve a secure, airtight connection, essential for the safe operation of your chimney system.
Key Features and Their Benefits
- Durable Construction: Manufactured from high-quality stainless steel, this adaptor is built to withstand high temperatures and severe weather conditions, ensuring longevity and reliability.
- Tapered Fit: The uniquely designed tapered end accommodates slight variations in clay liner shapes, reducing the risk of installation errors and enhancing safety.
- Versatile Offset Options: Available in offsets of 25mm, 50mm, or 75mm, this adaptor can be tailored to suit a variety of installation needs. The flexibility in design means you can choose the exact configuration required for your chimney setup.
- Compatibility with Installation Accessories: When used in conjunction with Fire Cement, Fire Rope, and stainless steel screws, the adaptor ensures a secure and durable connection, reducing risks of leaks and poor sealing.
Installation Process
Pre-Installation Checks:
- Verify that the existing clay liner is in good condition and has passed the necessary smoke tests. A compromised liner can result in installation failure.
- Gather all necessary installation accessories: Fire Cement, Fire Rope, and stainless steel screws are integral to a secure installation.
Installation Steps:
1. Positioning: Begin by aligning the Ø 200 25mm Offset Internal Clay Adaptor with the designated area on the chimney stack where the clay liner is present.
2. Insertion: Gently knock the tapered clay end into the resilient and sometimes uneven clay liner. The taper ensures a snug fit, which is critical for achieving an airtight seal.
3. Sealing: Apply Fire Cement and Fire Rope around the perimeter of the clay liner to secure the adaptor. This step is essential for preventing draft and enhancing safety.
4. Securing: Use stainless steel screws to firmly attach the adaptor to the chimney stack. These screws are specifically chosen for their anti-corrosive properties, ensuring the longevity of your installation.
Post-Installation Checks:
- Inspect the installation for any gaps or improperly sealed areas.
- Allow adequate curing time for the Fire Cement before operating the chimney system.
- Consult a professional if any issues arise or if further adjustments are needed.
