Our Sump Adaptor (325mm sq. plate) - Ø 150mm is designed for reliable integration with chimney stacks that feature a clay liner but don't require a separate flue liner. Constructed from durable 1mm thick stainless steel grade 316, it guarantees longevity and resilience.

To ensure optimal performance and safety, always smoke test your clay liner before installation. To install, position the 325mm square plate against the chimney stack's bottom, marking where the adaptor can be securely attached. After drilling and securing, use fire cement and fire rope for an airtight seal.

The single wall pipe can then be fitted over the spigot, finalized with more fire cement and fire rope if needed. Perfect for both trade professionals and home projects.
