EchoFlame™ Black Glass Lining

Inside the Onyx Eclipse is our elegant EchoFlame™ Black Glass Lining, which complements the flame display with a mirror polished finish that reflects the rolling flames, for added visual depth and grandeur.

Immersiflame triple burner system 

For a true-to-life log fire ambience, the Onyx Eclipse utilises our state-of-the-art ImmersiFlame triple burner architecture. Complementing the base burner are two secondary burners, concealed within the hand-painted Split Oak Log fuel effect, producing flames that envelop the log piece from bottom to top. When combined with our EchoFlame™ Black Glass Lining, the result is a multi-dimensional flame display that mimics the magic of real burning logs.

Natural Gas and LPG models

These mesmerising conventional flue gas inset fires are available as natural gas and LPG models, both of which feature our premium non-reflective glass for a crystal-clear view of the spectacular rolling flames. For added installation ease, both models can be paired with the additional minimalist Edge+ frame, for an effortless smooth finish to the recess.

Compatible with a choice of stone mantels 

What’s more, with their portrait fireboxes able to be hearth mounted, Eclipse 60HL gas fires are well suited to be installed within a stone mantel to create a traditional and elegant centrepiece.

Complete control 

Eclipse Gas Fires feature a compact, fully integrated control system, putting ignition, flame adjustment, heat output and extinguishing right into the palm of your hand. The included remote handset also offers thermostatic control, so your Eclipse can keep the room at the temperature you desire. The ergonomically designed remote control has the added benefit of a grip-lock safety feature, with sensors that activate the remote only when you are cradling it in your hand. This ensures your Eclipse cannot be accidentally switched on or operated, adding an extra layer of safety.
