Designed to fit into a fireplace surround, this glass-fronted fire brings unparalleled realism, warmth, and style, making it an ideal choice for both modern and classic interiors.
A perfect companion to modern fireplace surrounds, the fire features the stunning Autograph fascia, available in a choice of four designer finishes, each crafted to complement a range of home décor styles.

The beautifully crafted fascia not only frames the flames but adds a premium finish that enhances the overall elegance of your fireplace.
A Stunning Flame Display with Cutting-Edge Technology
At the heart of the Ultiflame Ultra SL Autograph is Celsi’s Multi-Flame Projection® Technology, which delivers a deep, three-dimensional flame effect that moves naturally, replicating the depth and flicker of a real fire. The flames rise above a realistic log fuel bed, made from handcrafted Natural Oak logs and Ash Embers, which glow gently, adding to the incredibly authentic feel of this electric fire. The inclusion of Living Ember Bed Technology® further enhances this effect, providing the soft, pulsing glow of burning embers, making it a truly mesmerising addition to your home.
Boasting customisable flame effects, offering 16 different colour options and a dynamic animation mode, allowing you to change the ambience to suit your mood. Whether you prefer a warm golden glow for cosy nights in or a contemporary blue hue for a more modern look, this fire offers endless possibilities. The brightness and flame speed can also be adjusted, meaning you can fine-tune the display to perfectly complement your space.
Comfort & Convenience – Efficient Heating with Smart Controls
Beyond its aesthetic appeal, the Celsi Ultiflame Ultra SL Autograph is designed with practicality in mind, offering flexible heating options to ensure your home stays warm and inviting. The 1.5kW thermostatic fan heater provides instant heat when needed, making it an excellent supplementary heat source for those chilly evenings. The thermostatic control allows you to set your desired room temperature, and the fire will automatically adjust the heat output to maintain a comfortable environment. If you simply want to enjoy the beauty of the flames without the warmth, the flame-only mode lets you do just that, making this fire perfect for year-round use.
Managing the settings of your fire has never been easier, thanks to its multiple control options. The included thermostatic remote control allows you to adjust the temperature, flame effect, and brightness from the comfort of your sofa, while the Celsi smart app, available for both iOS and Android, provides even more convenience, allowing you to control your fire from your phone or tablet. For those who love smart home integration, the Ultiflame Ultra SL Autograph is also compatible with Amazon Alexa and Google Assistant, meaning you can adjust the settings using simple voice commands. Whether you want to turn on the fire, change the colour, or adjust the brightness, all you need to do is ask.
Versatile Installation for Any Home
Designed to fit into a fireplace surround, the Ultiflame Ultra SL Autograph requires just a 70mm inset depth, making it suitable for flat wall installations when combined with a 3” rebate fireplace surround. If you don’t have a recess available, an optional freestanding spacer frame allows the fire to be installed flush against a flat wall, making it a great option for those looking for a stylish heating solution without major installation work.
A Perfect Blend of Style, Innovation & Warmth
The Celsi Ultiflame Ultra SL Autograph Electric Fire enhances the beauty of your home. With its stunning fascia options, ultra-realistic flames, smart home compatibility, and energy-efficient heating, it provides everything you need to create a cosy and stylish atmosphere at the touch of a button. Whether you’re looking for a contemporary centrepiece for your living room or a modern upgrade to a traditional fireplace, the Autograph model is a perfect choice.
