RF Remote Control
Intuitive Control at Your Fingertips
With the RF remote control, you can operate the fireplace easily and precisely from anywhere in the room. Effortlessly switch the fireplace on or off, manually adjust the flame height, or set your desired room temperature.
The remote also features a programmable timer, allowing you to automatically schedule ignition times based on your daily routine. The Ecowave function can be activated at the press of a button.
For optimal performance, the remote should be kept at room temperature. RF technology ensures a reliable connection without the need for direct line-of-sight, placing comfort and simplicity at the heart of your daily fireplace operation.
Double Burner
Comfortable Fire at 50% Power Output
For the AVENUE collection, Metalfire developed an innovative burner system composed of two separate burners. This gives the user full control over both the flame appearance and the heating capacity.
For a cozy atmosphere and gentle warmth, only the inner burner can be activated. It produces a refined, realistic imitation wood fire at approximately 50% of the total output — ideal when the fire serves a decorative purpose.
For maximum heat output, both the inner and outer burners can be activated. In this mode, the fireplace delivers its full capacity, creating a rich, full flame effect with intense warmth.
Combined with the ECOWAVE function — which creates a dynamic, natural flame pattern — this system offers an unmatched balance between comfort, ambiance, and efficiency, tailored to every moment of the day.
Flexible Flame Control with Maximum Atmosphere.
Ecowave Feature
Efficient and Dynamic Flame Control
Up to 40% Savings on Gas Consumption
With the ecowave feature, enjoy a lively, authentic-looking fire while saving up to 40% on gas consumption. The system smartly adjusts the flame between high and low settings, crafting a vivid and realistic wood fire effect, especially when paired with our ceramic logs. It's the smart way to indulge in the beauty of a natural fire without the high energy costs—dynamic, visually appealing, and cost-effective.
Fuel Choice: Versatile and Eco-Friendly Choices
Metalfire gas fireplaces are by default designed for connection to natural gas, but they are also perfectly compatible with propane or biopropane. These alternatives provide a reliable solution for projects where natural gas is unavailable or where there is a conscious choice for a more sustainable or off-grid energy approach.
Thanks to this fuel flexibility, Metalfire fireplaces can be integrated into a wide range of building contexts — from urban homes to rural new-builds and energy-neutral concepts. This allows you to combine architectural freedom with energy efficiency and long-term vision.
H2NG Ready
Future-Oriented Technology, Built In Today
As part of a European innovation project, the AVENUE PLUS and AVENUE collections were extensively tested with the gas of the future: a blend of hydrogen (H₂) and natural gas (CH₄). This so-called H2NG mixture — containing up to 40% hydrogen — presents a sustainable alternative in the energy transition.
Thanks to a carefully engineered burner architecture, AVENUE PLUS and AVENUE fireplaces operate flawlessly on H2NG — without requiring any modifications to the appliance. This makes Metalfire fireplaces ready for a future in which hydrogen is gradually integrated into the existing gas network.
With this innovation, Metalfire reinforces its commitment to sustainability, technological advancement, and long-term reliability in every architectural fireplace concept.
Line Burner
Refined Flame Aesthetics in Architectural Perfection
Within the Avenue collection, the line burner symbolizes pure simplicity and sophistication. This elongated gas burner is designed for those who appreciate a clean, linear flame without visual interruption. The stylized flame line runs elegantly along the full length of the fireplace, creating a strong horizontal accent in any interior.
Thanks to its discreet placement and minimalistic structure, a harmonious dialogue arises between the fire and the architectural surroundings. The line burner is especially suited for minimalist designs, where the presence of fire enhances the space without dominating it.
As with all Avenue appliances, a wide range of decorative finishes is available — from stones and wood chips to ceramic logs — each carefully matched to the burner type and desired style.
Metalfire’s Line Burner: where sleek design and warm ambiance meet.
Log Burner
Layered Flames, Pure Nature
Within the Avenue models featuring a combustion opening of 60 or 75 cm, Metalfire introduces its patented Mountain Burner — an innovation that elevates the flame experience to a new level. This exclusive burner technology is designed to create a layered, dynamic flame pattern, with variations in flame height and an organically spread fire effect..
THE LOG BURNER RECAPTURES THE ESSENCE OF WOOD FIRE — WITH THE PRECISION OF GAS
What makes this burner truly unique is the natural glow that emerges beneath the ceramic logs — without the use of LED lighting or artificial effects. The result is a flame pattern that closely mimics the character of a real wood fire, while offering the comfort, control, and reliability of gas.
The Mountain Burner is specifically developed for use with log sets and is not compatible with stones or wood chips. This deliberate choice emphasizes authenticity and a genuine fire experience.
Metalfire’s Log Burner: for those who seek the essence of fire — in its most perfectly controlled form.
Custom Convection Slots for Enhanced Fireplace Efficiency
Upgrade your fireplace with a convection slot—designed to improve heat distribution and energy efficiency by circulating warm air evenly throughout your space. This innovative feature enhances comfort, reduces heating costs, and ensures a safer, more effective fireplace experience.
Our convection slots are available in three stunning colors Black, Terracotta or Maple Gold and can be customized to your exact measurements, ensuring a perfect fit for any fireplace design. Whether for new installations or retrofits, this solution combines functionality with style.
Door System
Simple and Subtle
For an optimal view of the fire and the sleekest design without any visible frame or screening, all the fireplaces in the AVENUE collection are fitted with a glass plate that can be removed using the suction cups provided. No further tools are needed. One simple movement frees the glass, which can then be removed without difficulty. Easy to use, and quick to install and to maintain! Optionally available with PREMIUM anti-reflective glass.
Positioning the Fireplace
The fireplace is fitted with four adjustable feet.
These feet can be adjusted in height both internally and along the outer side of the fireplace. If the highest foot position is insufficient, a supporting construction on which the fireplace can be placed must be installed. This must be stable and strong enough to bear the weight of the fireplace.
You can recognise our craftsmanship by the calligraphy logo on the glass or finishing frame.

Interior Finishing
Original | Triangle | Round | Design | Standard
Within Metalfire’s range of interior finishes, the cast iron slats Original, Triangle, and Round stand out for their refined aesthetics. Each version reflects a unique interpretation of minimalist design. Original features vertical ribs in a clean, classic rhythm. Triangle, with its angular profile, adds a graphic dimension to the flame effect. Round, designed in collaboration with Belgian architect Benoit Viaene, contrasts with soft, rounded forms that create a harmonious interplay with the flames.
What unites these options is their rhythmic linear design, each offering architectural added value — even when the fireplace is not in use. These cast iron interiors serve as true design elements within any interior concept.
In addition to these characterful finishes, Metalfire also offers Standard (flat steel plate) and Design (asymmetrical pattern) — ideal for those seeking either simplicity or a subtle design tension.
All finishes are available within the Avenue and Avenue Plus range and can be perfectly matched to the overall fireplace concept.
THE COMMON THREAD IS THE ELEGANT RHYTHM IN BOTH SURFACES, CREATING AN ENGAGING DIALOGUE WITH THE WARM GLOW OF THE FIRE
Ceramic
Concrete Look
In our pursuit to offer you the most diverse and customizable options, we are pleased to introduce a new interior finish variant. In addition to cast iron and steel, the Avenue is now also available in a Ceramic concrete-look finish.
This ceramic material brings a modern, industrial charm to your space while maintaining the high-quality characteristics that define this durable and refined surface.
Finishing Colours
Black | Terracotta | Maple gold
The elegant black standard finish remains a timeless staple within the Metalfire offering. This classic coating brings a sense of calm and refinement to any interior. Yet design evolves — and Metalfire now introduces two new color variants: Terracotta and Maple Gold.
With these additions, Metalfire offers architects and interior designers greater freedom to visually integrate the fireplace into the overall concept. Terracotta adds a warm, earthy touch, while Maple Gold introduces a subtle glow and sophistication — ideal for projects where texture and material expression take center stage.
These finishes are available within the Avenue and Avenue Plus collection and can also be applied to framing options and bespoke fireplace concepts.
In this way, each fireplace becomes not just a source of warmth, but a personal architectural statement.
THE EXTENDED COLOR SELECTION IS ALSO AVAILABLE FOR FRAMING OPTIONS AND BESPOKE CONCEPTS, OFFERING EVEN MORE POSSIBILITIES TO TAILOR THE DESIGN TO PERSONAL TASTE
Standard Burner Finish
Woodchips| Vermiculite | Grey pebbles | White pebbles
For appliances with a combustion opening of 40 cm, Metalfire offers a selection of decorative burner toppings that enhance the flame effect and define the character of the fireplace. White stones come as standard, adding a bright, clean accent to the flame image.
Additionally, grey stones and black wood chips are available — each bringing its own texture and ambiance. For those seeking a more realistic, warm appearance, ceramic logs in Classic Style are also offered. These create an authentic fireplace feel, with realistic wood textures and natural color nuances.
Each finish contributes to a unique fireplace experience, perfectly aligned with the interior concept and architectural context.
Logburner Finish
Smoke Style Ceramic Wood Logs
For gas fireplaces with a combustion opening of 60 or 75 cm, Metalfire deliberately opts for a contemporary and refined aesthetic. These appliances come standard with ceramic logs in Smoke Style — a look that conveys strength and serenity, featuring a subtly weathered wood appearance that integrates perfectly into modern architectural interiors.
The Smoke Style finish enhances the realism of the flame effect and creates a rustic yet stylized fire image. These burners are exclusively available with this ceramic log set; stones or wood chips are not compatible with this configuration.
The result is an expressive yet understated fireplace experience — ideal for projects where form, texture, and flame aesthetics must be perfectly balanced.
Logburner Finish
Classic Style Ceramic Wood Logs
For those who appreciate the warm ambiance of a traditional wood fire, Metalfire offers a refined option: Classic Style Ceramic Logs. These carefully crafted pieces combine the visual realism of real wood with the durability of high-quality ceramic.
By default, appliances with a 40 cm combustion opening are delivered with white stones. Upon request — and at no additional cost — grey stones or wood chips are also available. For those seeking even greater atmosphere and authenticity, the Classic Style Ceramic Logs are available as an optional upgrade.
This finish elevates the gas flame experience and fits seamlessly into interiors with a classic or rustic signature — or as a warm accent in a contemporary project.
