The Rocal ARC 76 LI corner wood-burning inset fire is a 9.8kW cassette-style fire with left side glass, designed for contemporary fireplace builds where a wider flame view is required. With 84% efficiency, an A+ energy rating and an output range of 6.5–11.5kW, it delivers efficient wood-burning performance in a compact corner inset format.
The left side glass version is best suited to installations where the left-hand side of the fire remains visible from the room. This allows the flames to be enjoyed from both the front and left side, creating a more open, architectural feature than a standard front-facing inset fire.
The ARC 76 LI is available as a frameless inset fire for a minimal built-in appearance or with a 4-sided frame where a more defined fireplace edge is preferred. This makes it suitable for different wall finishes, chimney breast designs and contemporary fireplace layouts.
With a nominal output of 9.8kW, this model is suitable for rooms that need meaningful heat from a compact inset fire. Optional fan-assisted convection can be added to help move warmth further into the room, using two fans to improve heat circulation in larger spaces. This option requires an electricity supply, while natural convection is available as standard.
The fire supports an external air supply from the rear or base, giving useful flexibility during installation planning. Convection air ducting is also included, helping the appliance work effectively as part of a built-in fireplace or chimney breast design.

Expert Insight
The left side glass version should be selected when the left-hand return of the fire will remain visible and add value to the room design. Frame choice is also important: frameless gives the cleanest built-in look, while the 4-sided frame creates a clearer finished border around the appliance. External air routing, convection ducting and any fan-assisted convection power supply should be planned before the fireplace structure is built.
