  • A high-efficiency balanced flue gas fire for homes without a chimney, featuring realistic mixed logs, glowing embers, and an impressive 89% efficiency.

    The Paragon Core BF Balanced Flue Gas Fire is designed for homes where a conventional chimney is not available. Using Paragon’s advanced Core burner technology, this glass-fronted gas fire delivers realistic flickering flames, glowing embers, and a beautifully detailed mixed log fuel bed.

    With a high efficiency of 89%, the Core BF offers excellent performance alongside the convenience of balanced flue installation. It is ideal for homes where the original chimney has failed, been removed, or was never present.

    Designed for Homes Without a Chimney

    The Core BF is a balanced flue gas fire, making it suitable for properties without a traditional chimney or flue system.

    It can be mounted into walls up to 780mm thick, with a maximum flue length of 600mm, allowing it to be used in homes where the chimney has been removed at roof level or is no longer suitable for use.

    Realistic Mixed Log Fuel Bed

    The Core BF features a realistic mixed log fuel bed, designed to look attractive both when the fire is lit and when it is not in use.

    The combination of flickering flames, glowing embers, and black reflective glass liners creates a deep and atmospheric flame picture.

    High-Efficiency Core Burner Technology

    The updated Core burner and terminal design delivers an impressive 89% net efficiency to BS EN 613:2021.

    This makes the Core BF one of Paragon’s most efficient natural gas inset fires, providing effective warmth with excellent fuel performance.

    Control Options

    The Paragon Core BF is available with a choice of control systems to suit your preference.

    Choose from:

    • Slide control
    • Full sequential remote control

    This allows you to select the operation style that best suits your home and everyday use.

    Fascia, Trim and Fret Compatibility

    The Core BF is suitable for use with the current Charlton & Jenrick range of trims, frets, and fascia options.

    This gives you flexibility to tailor the final look of the fire, from traditional to contemporary styling.
