FAQs

Yes, the Screw-FIX Top Hat Adaptor is compatible with wood (<20% moisture), smokeless coal, gas, and oil appliances.

No, Building Regulations Document J requires that flexible flue liners be fully enclosed within a masonry chimney. Non-masonry enclosures are not acceptable.

For best results, use fire cement, ceramic rope, or high-temperature sealant to make a gas-tight seal between the adaptor and the flexible flue liner.

While it's possible for experienced DIYers to install the adaptor, we recommend using a certified professional for safety and compliance with building regulations.

Chimney systems should be inspected and cleaned at least once a year. For solid fuel appliances, it's advisable to sweep the chimney twice a year: at the end of the heating season and before the start of the next one.
