The Onyx Liv 3 Gas Fire

Combining a sophisticated cylindrical design with stunningly realistic flames and log effects, the Onyx Liv 3 gas fire creates an unmistakably contemporary centrepiece in any home. Offering 180º views of the fire, the sweeping curves and clean lines showcase the Liv 3’s panoramic three sided flame visuals. Inside the firebox, life-like flame burner technology and realistic logs help to create a tall, lazy fire which will captivate you. The EchoFlame Black Glass backdrop provides a mirror polished finish to increase visual depth and definition.

Complete Flame and Fire Control

The Onyx Liv 3 gas comes with a fully integrated remote control system. This allows you to ignite the fire, adjust the flame effects, control the heat output and extinguish the fire all from the palm of your hand.  The thermostatic temperature controls also allow you to set and maintain your desired room temperature at the touch of a button.
