FAQs

Pack 704 includes a 180mm top plate, 180mm top clamp, 180mm nose cone, an increasing adaptor (150mm SW to 180mm Flex), and a chimney notice plate.

Yes, it's suitable for wood with less than 20% moisture, smokeless coal, gas, and oil appliances, supporting temperatures up to 600°C.

No, Building Regulations Document J dictates that flexible flue liners must be fully enclosed within a masonry chimney. Non-masonry enclosures like timber or plasterboard are not acceptable.

The increasing adaptor helps transition from a 150mm single wall to a 180mm flexible liner, ensuring a secure and efficient connection.

While not included, a chimney cowl or terminal is recommended to offer weather and bird protection for your chimney.

It's recommended to sweep solid fuel chimneys twice a year: once at the end of the heating season and once before the next season begins. Annual inspections and maintenance of the appliance are also advised.
