Luxury Flame Design Meets Cutting-Edge Control

Crafted for modern living spaces, the Onyx Avanti Gas Fires bring together premium design, advanced technology, and effortless comfort. With their sleek exteriors and ultra-realistic flame visuals, these inset gas fires create a stunning centrepiece in any contemporary home.

Available in two sizes – the Avanti 65 and Avanti 85 – each model features the signature EchoFlame™ Black Glass Lining, offering a deep, reflective backdrop that enhances the layered flame effect. A hand-painted oak log-effect fuel bed adds natural charm, delivering an immersive and authentic fire experience.

Whether you choose a natural gas or LPG model, both sizes can be finished with your choice of stylish frame:

• Expression Frame – Bold, architectural statement

• Edge+ Frame – Minimalist sophistication for seamless integration

Control is effortless thanks to the fully integrated remote handset, giving you full command over flame height, heat output, and thermostatic settings, all from the comfort of your seat.
