At the base of a Blue System installation, the starter section acts as the initial connection point between the boiler outlet and the single-wall external plume components. This version is designed for the 100mm Blue System used on Grant oil boilers in the 26–70kW output range and incorporates a combustion test point for routine servicing and commissioning.
The section provides a stable starting position for the rest of the flue run, ensuring the transition from the boiler spigot to the external plume pipework is properly supported. By supplying a secure joint and an accessible test point, it enables technicians to verify combustion performance without dismantling downstream components during annual checks.
Once installed, the starter section aligns with elbows, plume diverter kits, fixed extensions and terminals found throughout the Oil Boiler Flues range. As with all Blue System components, it must be considered within Grant’s overall plume-management rules, including limits on vertical rise and adjustments when angled fittings are included in the route.
