This flexible flue kit provides a 10-metre smooth-bore chimney liner for connecting Grant oil boilers to an existing masonry chimney. It is designed for installations using a conventional (open-flue) arrangement and supports boiler outputs from 12kW to 46kW. The 100mm liner is supplied as part of a complete pack containing the essential components required for a safe and continuous chimney run.
The stainless-steel liner is manufactured to allow smooth internal airflow while maintaining flexibility for navigating bends inside older chimney structures. Top plates, adaptors and a terminal are included so the entire length can be secured and finished without additional parts. This makes the kit suitable for chimney heights close to 10 metres, where a longer liner is essential for correct draught and system performance.
As part of Grant’s Orange System range, this kit is typically used in buildings where the existing chimney is retained, connecting the boiler through the appropriate adaptors found within the Oil Boiler Flues category. Installers must follow the manufacturer’s guidance, including BS5410 ventilation requirements and any local regulations affecting conventional-flue systems.
