This 1000mm extension is a full one-metre section used within Grant’s EZ-Fit Blue System to build longer external flue and plume routes for boilers up to 26kW. It provides a substantial straight length that helps form extended vertical rises or horizontal offsets where shorter sections would require multiple joints.
The extension fits directly into 80mm Blue System pipework using the locking band supplied, creating a continuous and stable section of the flue run. Its length offers an efficient way to cover larger distances with fewer fittings, improving alignment and reducing the number of mechanical joints needed on an external wall or boiler-house installation.
As part of the wider Blue System range, this component links seamlessly with elbows, plume diverter kits, wall brackets and either high-level or vertical terminals available through the Oil Boiler Flues category. Planning rules for plume management still apply, including the maximum 6m vertical rise and deductions where 45° elbows are introduced into the route.
- Provides a full 1000mm fixed Blue System section
- Designed for 80mm external flue or plume runs
- Compatible with Grant boilers up to 26kW
- Reduces the need for multiple shorter pieces
- Locking band included for secure jointing
