Ensure the adaptor is fitted at the base of your chimney, directly beneath the register plate. For optimal performance and safety, it is recommended that installation is carried out by a HETAS registered professional. Proper alignment is crucial, and any gaps must be sealed with high-temperature sealants such as fire cement, ceramic rope, or specialised tape. Avoid using chemical cleaners or mild steel tools during cleaning, as these can damage the stainless steel surface. Regular chimney maintenance, including cleaning and checks by a competent person, is essential to maintain the efficiency and longevity of your installation.

The Top Hat Adaptor is made from 1mm thick 316 stainless steel, known for its durability and resistance to high temperatures.

Yes, the adaptor is suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil.

The Top Hat Adaptor should be installed at the base of the chimney, on the underside of the register plate.

To ensure a gas-tight seal, use fire cement, ceramic rope, tape, or high-temperature sealant.

While it is possible to install the adaptor yourself, we recommend having the installation done by a competent person to ensure safety and compliance with Building Regulations.

Chimneys serving solid fuel appliances should be swept at least twice a year, preferably at the end of the heating season and before the start of the next.

No, chemical cleaners or mild steel tools should not be used. It's best to use appropriate brushes and tools designed for stainless steel to avoid damage.
