Plus, with the addition of a self-programmable timer, you can customize your fireplace's operation to fit your schedule. For optimal performance, ensure the remote control is kept at room temperature.

Dual burner innovation

A delightful fire at 50% power

Experience the warmth of a charming fire at half the intensity with our newly designed dual burner system, created exclusively for the Avenue Collection. Integrating the energy-efficient ECOWAVE feature, this advanced system boasts two independent burners. Activate just the inner burner for a cozy vibe and enjoy a beautifully limited yet realistic imitation of a wood fire, consuming merely half the energy typically required. It's the perfect solution for those seeking the ambiance of a flickering flame with a reduced heat output. For those occasions when more warmth is desired, operating both the inner and outer burners will harness the full heating power of the system, ensuring a delightful experience of both light and warmth.

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 Options: Versatile and Eco-Friendly Choices

Metalfire's gas fires are designed for versatility, accommodating natural gas connections. Should natural gas be inaccessible or phased out, we offer environmentally friendly alternatives like propane and biopropane, ensuring a seamless transition and continued enjoyment of your fireplace.

Future-Proof Innovation: H2NG Compatibility

Embracing the future of sustainable fuel, our AVENUE+ and AVENUE collections are primed for the next generation of energy. As part of a pioneering European initiative, these collections have been rigorously tested with a forward-thinking blend of hydrogen and natural gas—up to 40% hydrogen mix. Engineered for excellence, our fireplaces require no modifications to burn this hybrid fuel efficiently, positioning the AVENUE+ and AVENUE as leaders in eco-friendly, future-proof home heating.

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.

Interior finishing

Original | Triangle | Round | Design |Standard

Like the 'Original' vertical cast-iron slats, the new finishes of the Triangle and Round versions exude minimalism. While these innovative additions stay true to Metalfire's love of clean and simple design, they also add a certain dynamism to our range. The Triangle cast-iron slats represent a more angular approach to the inside of the fireplace, while the Round cast-iron slats - based on a design by belgian architect Benoit Viaene - are characterised by gentle curves. The common denominator is the elegant rhythm in both surfaces, which creates an interesting dialogue with the warm light of the fire. The sleek and refined finish of the Original, Triangle and Round versions fits perfectly into any interior (in any fireplace) and is also a real eye-catcher, whether the fire is burning or not. Besides, we also offer a flat and asymmetrical finish namely Standard and Design.


Concrete look

This new interior finish, several panels together create a beautiful concrete look for a trendy and timeless effect. Thanks to its enormous heat resistance, it is ideal as interior cladding for fireplaces.

Finishing colours

Black | Terracotta | Maple gold

The standard black finish already gives every fireplace a stylish, timeless allure, but now Metalfire is announcing two new colours in its cast iron finish collection. 'Terracotta' and 'Maple Gold' breathe new life into the range and allow our customers to further tailor their premium fireplace to their personal style. The new colours are available for both open and closed gas fires. Also available for finishing frames and customised concepts.

Burner finish

SMOKE Style ceramic wood logs

Appliances with a 60 and 75 cm fireplace opening: Fitted as standard with Smoke Style ceramic wood logs. These appliances are NOT available with pebbles or woodchips.


Belgian craftsmanship is Metalfire's credo. Every day, the vision of extraordinarily unique fireplaces is put into practice by the expert hands of skilled craftsmen. It creates a unique appeal that by automated production processes simply cannot be imitated.

Metalfire's no limits attitude allows ample possibilities in customization, finishing frames, fireplace concepts, wood storages and extensions. Customization supports the creative vision of the architect or interior designer, all within the imposed standards.

You want it, we create it. Metalfire's motivation to blend into the architecture and the interior of the home as a whole, is what sets us apart from the masses.
