The WX150/100 Conventional 150mm Flue Extension is suitable for Grant Vortex boiler models with outputs of up to 46kW, making it a useful option when extra flue length is required.

With a fixed length of 150mm, this extension provides a straightforward way to increase the length of a compatible conventional flue system. It is designed specifically for suitable Grant Vortex boilers up to 46kW.

Manufactured from metal with a single-skin stainless steel construction, the extension is designed to provide a quality and reliable flue component. Its white powder-coated finish gives it a clean appearance that complements the rest of the compatible Orange System components.

Easy and Secure Installation

The Grant 150mm Extension is supplied with a locking band, helping provide a secure connection between compatible flue components. Its simple design makes it a practical accessory for installers who need to add a fixed amount of length to the flue system.

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.

If you're ordering multiple products from the same supplier, your order will be dispatched together once all items are ready. This means the longest lead time will apply.
