Product Information

Grant Low Level Balanced Flue Round Extension

The Grant Low Level Balanced Flue Round Extension is designed to provide additional flexibility when installing compatible balanced flue systems. Made from stainless steel and designed for quick and straightforward installation, it is a practical option when additional flue length is required. The extension forms part of Grant's low-level balanced flue system and features a compact design. This makes it particularly suitable for installations where the appearance of the completed flue is important, helping maintain a neat and discreet finish.

Available Variants

The Grant Low Level Balanced Flue Round Extension is available in three variants to suit different boiler output ranges and installation requirements. For 50-90 BTU applications, both 225mm and 450mm lengths are available. A 225mm option is also available for 90-200 BTU applications. This range of sizes gives installers greater flexibility when determining the required flue length for a particular installation.

Flexible Flue Installation

The Grant balanced flue system can accommodate horizontal lengths of up to 4 metres, including configurations using one 90° elbow or two 45° elbows. This provides useful flexibility when routing the flue around obstacles or adapting the installation to suit the property.

Compact and Practical Design

The flue terminal has been designed with a compact profile, making it a good choice where visual appearance is an important consideration. The stainless steel construction provides a quality finish while the straightforward design helps make installation quick and simple.

Plume Management Options

Grant also offers plume diverter kits designed as a solution for existing low-level flue installations where plume discharge is causing a nuisance. This provides an option for managing plume issues without necessarily requiring a completely new flue arrangement, subject to compatibility and installation requirements.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
