This 1000mm extension pipe is part of Warmflow’s Easy-Fit balanced flue system and is used when a flue run requires additional length to meet the chosen exit point. The section maintains the concentric room-sealed arrangement, ensuring stable combustion air intake and reliable discharge of flue gases. Its rigid polypropylene construction can be trimmed to size where required, allowing installers to create accurate, well-aligned flue routes.
The extension integrates directly with elbows, terminals and starter pieces in the Warmflow F-series, providing flexibility in both horizontal and vertical layouts. When planning longer runs, engineers must consider equivalent length rules to ensure the total system resistance stays within manufacturer limits. Proper planning is especially important when extension pipes are combined with plume management components on oil boiler flues, where overall airflow balance must remain stable.
The Easy-Fit twist coupling ensures quick, secure connection without the need for additional sealants. When installed with continuous fall back to the boiler, this extension helps maintain correct condensate return and supports long-term reliability across all compatible Warmflow HE models.
- Adds 1000mm to balanced flue runs
- Cut-to-length capability for precise installation
- Fully compatible with all F-series components
- Maintains sealed combustion system integrity
- Suitable for horizontal and vertical layouts
